We are publishing extra page using event system on publishing event of pages.
It is working well when we publish a page from the CME. When we create a page using Tridion UI, it is created and published as expected but the event system throws error when it tries to create a target type object.
try
{
foreach (var t in e.Targets)
{
var targets = new List<TargetType>();
some logic
targets.Add(new TargetType(t.Id, page.Session)); // error is in this line
PublishInstructionBase pib = e.PublishTransactions.First().Instruction;
PublishInstruction pi = new PublishInstruction(page.Session);
pi.StartAt = pib.StartAt;
pi.RollbackOnFailure = pib.RollbackOnFailure;
PublishEngine.Publish(
items,
pi,
targets,
PublishPriority.Low
);
}
}
Exception we are getting is InvalidURIException
Both t and Session are not definitely not null which we verified by writing log over there.
Please do suggest what we can to fix the issue?
We manage to fix that by little hack putting code in try catch and creating target type manually if there is exception as we do know Tridion UI publish to staging only initially.
Thanks,

It's hard to tell without exception and stack trace, but I assume you need to read TargetType first and not try to create it, like this:
(TargetType) page.Session.GetObject(t.Id)
It might be that the URIs you use are not from the same Publication context and are therefore invalid.

How to set up the SQL Server database for Semantic logging.
Does the table for logging information needs to be created earlier?
If yes, what is the schema to be used.
I have the following code :
var listener = new ObservableEventListener();
string connectionString = #"Data Source=nibc2025;Initial Catalog=TreeDataBase;Integrated Security=True;User Id=sa;Password=nous#123";
listener.EnableEvents(AuditingEventSource.Log, EventLevel.LogAlways, Keywords.All);
databaseSubscription = listener.LogToSqlDatabase
(
"Test",
connectionString,
"Traces",
Buffering.DefaultBufferingInterval,
1,
Timeout.InfiniteTimeSpan, 500
);
// The following one line of code is not part of this function.
// It is just added here to show this is how I log my information.
// Inside LogInformation method I call the 'Write' method
AuditingEventSource.Log.LogInformation("sgsgg", "sgsg");
databaseSubscription.Sink.FlushAsync().Wait();
Well, Since this thread gets the most hits on Google regarding Semantic Logging onto SQL DB or even SLAB ...
The scripts to create the DB lies here
\packages\EnterpriseLibrary.SemanticLogging.Database.1.0.1304.0\scripts
And to create the EventSource and Fire the Blocks, information are given here, for a shortcut and quick fix solution

Regards,
OK. I got it. the script was in the packages folder. I had overlooked that.
First off, this question has been covered a few times (I've done my research), and, for example, on the right side of the SO webpage is a list of related items... I have been through them all (or as many as I could find).
When I publish my pre-compiled .NET web application, it is very slow to load the first time.
I've read up on this, it's the JIT which I understand (sort of).
The problem is, after the home page loads (up to 20 seconds), many other pages load very fast.
However, it would appear that the only reason they load is because the resources have been loaded (or that they share the same compiled dlls). However, some pages still take a long time.
This indicates that maybe the JIT needs to compile different pages in different ways? If so, and using a contact form as an example (where the Thank You page needs to be compiled by the JIT and first time is slow), the user may hit the send button multiple times whilst waiting for the page to be shown.
After I load all these pages which use different models or different shared HTML content, the site loads quickly as expected. I assume this issue is a common problem?
Please note, I'm using .NET 4.0 but, there is no database, XML files etc. The only IO is if an email doesn't send and it writes the error to a log.
So, assuming my understanding is correct, what is the approach to not have to manually go through the website and load every page?
If the above is a little too broad, then can this be resolved in the settings/configuration in Visual Studio (2012) or the web.config file (excluding adding compilation debug=false)?
In this case, there are 2 problems
As per rene's comments, review this http://msdn.microsoft.com/en-us/library/ms972959.aspx... The helpful part was to add the following code to the global.asax file
const string sourceName = ".NET Runtime";
const string serverName = ".";
const string logName = "Application";
const string uriFormat = "\r\n\r\nURI: {0}\r\n\r\n";
const string exceptionFormat = "{0}: \"{1}\"\r\n{2}\r\n\r\n";
void Application_Error(Object sender, EventArgs ea) {
StringBuilder message = new StringBuilder();
if (Request != null) {
message.AppendFormat(uriFormat, Request.Path);
}
if (Server != null) {
Exception e;
for (e = Server.GetLastError(); e != null; e = e.InnerException) {
message.AppendFormat(exceptionFormat,
e.GetType().Name,
e.Message,
e.StackTrace);
}
}
if (!EventLog.SourceExists(sourceName)) {
EventLog.CreateEventSource(sourceName, logName);
}
EventLog Log = new EventLog(logName, serverName, sourceName);
Log.WriteEntry(message.ToString(), EventLogEntryType.Error);
//Server.ClearError(); // uncomment this to cancel the error
}
The server was maxing out during sending of the email! My code was fine, but, viewing Task Scheduler showed it was hitting 100% memory...
The solution was to monitor the errors shown by point 1 and fix it. Then, find out why the server was being throttled when sending an email!
I have used the code below:
Iterable<Module> modules = ImmutableSet.<Module> of(
new SshjSshClientModule());
ContextBuilder builder = ContextBuilder.newBuilder(provider).endpoint(endpoint)
.credentials(identity, credential)
.modules(modules);
System.out.printf(">> initializing %s%n", builder.getApiMetadata());
ComputeService compute = builder.buildView(ComputeServiceContext.class).getComputeService();
System.out.println(compute1.listImages());
but I am getting the following error message.........
com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected a string but was BEGIN_ARRAY at line 1 column 787

The code was working... before...
You've definitely hit a bug somewhere between the version of jclouds you're using and whatever version of whatever cloud you're using. We'll need more information to fix this. Please go through the instruction on how to Report a Bug to Apache jclouds.
I need to stop publishing of a page when a certain condition exists, for example if the page name contains 'one' using the Event System. Also, the other pages should continue to publish.
I am thinking to use a PublisherException instead of a generic exception.
The problem is the I do not know the resourceName of the LocalizableMessage. Any ideas?
if (item.Title.ToString().Contains("one"))
{
Localization.LocalizableMessage errResource = new Localization.LocalizableMessage("error");
throw new PublisherException(errResource, new Exception("Can't get there from here!"));
}
The Event System can stop Publishing, there is no middle ground there though, when you throw an exception, it stops the entire transaction.
Like Puntero mentions, if you want to remove an item from a Publish Transaction, that is where a Custom Resolver comes in. From here you cannot communicate back to the Publish Transaction, but you have access to the Tridion Logger (eventlog):
Tridion.Logging.Logger.Write("your message string", "MyResolver", LoggingCategory.General, TraceEventType.Information);
With regards to your LocalizableMessage in the Event System, you should be able to do the following:
throw new PublisherException(new LocalizableMessage(Properties.Resources.ResourceManager, "PagePublishErrorMessage"));
Where the resourceName is pointing to the name of a String resource you have in your Project.
I agree with #Puntero that if you want other page in a publish action to go through, you should use a Resolver rather than an Event Handler.
I tried to raise a warning to alert users of one item not being resolved, but failed. But there may be some good tips/ideas for you here: Raising a “warning” status during SDL Tridion 2011 publishing
In the end, the only way I could get anything to work was to set "Allow X failures", and then do a check in a template, and raise the error there. That will count as a Render failure, and allow the publisher to move on to the next item in the publish transaction.
As for the message? What message would you like to display?
I created an image uploader for an app I am working on. I first used php for the server side script, and everything worked fine. I found out afterwards I had to use .net, so I created new serverside scripts. The problem I am having is that my event.COMPLETE listener is never firing. I can receive data back using a DATAEVENT listener, but then it stops at this error:
Error #2044: Unhandled IOErrorEvent:. text=Error #2036: Load Never Completed.
Here is how I am sending my file.
var fileRefReq:URLRequest = new URLRequest(FILE_UPLOAD_TEMP);
var fileReqVars:URLVariables = new URLVariables();
fileReqVars.subdir = "Temp";
fileRefReq.data = fileReqVars;
fileRefReq.method = URLRequestMethod.POST;
fileRef.upload(fileRefReq);
The file definitely gets uploaded to the first TEMP directory, but then it breaks with the above error.
Has anyone else had a similar problem or point me in the right direction for solving this?
This is an error produced by Flash. The most common causes are:
It could be a 404 Error you are getting somewhere in the Flash.
This error can occur if you close the browser while it is loading something.
By default, the calling SWF file and the URL you load must be in the same domain. For example, a SWF file at www.adobe.com can load data only from sources that are also at www.adobe.com. To load data from a different domain, place a URL policy file on the server hosting the data.
Number 3 is important because a common user problem with Flash is security issues - so it is just something to rule out. Most likely not the cause here.
I would test for these 3 causes and read over the URLRequest: http://livedocs.adobe.com/flex/3/langref/flash/net/URLRequest.html
After some additional thought I think it is timing out but that is just a theory. Add an event listener like so:
urlLoader.addEventListener("httpResponseStatus", function(event:HTTPStatusEvent):void
to see what is actually happening.
You have to handle the event such as:
// add the event listener
urlLoader.addEventListener( IOErrorEvent.IO_ERROR, onErrorHandler );
// handle the error event like this:
private function onErrorHandler( e: IOErrorEvent ): void {
trace( "An io error occurred." );
}
Hope that helps
