I'm using Xamarin.Forms 5.0.0.1874 and Prism 8.0.0.1909
I'm trying to use Regions and the region doesn't appear. In the callback for navigating to region I'm getting the following error
Prism.Ioc.ContainerResolutionException
An unexpected error occured while resolving Prism.Regions.IActiveRegionHelper
The application doesn't crash. The region just doesn't appear where is suppose to (if I understood the concept of regions correctly) I made a simple example with the code that I'm using. The example can be found in the following GitHub repository
https://github.com/gnout/PrismRegion
It's a known issue with Prism Unity container.
As provided by Dan here you can switch to Prism DryLoc while waiting for a fix on the Unity side.

Daydream is a chrome extension (by /segmentio on github) that records your actions into a Nightmare (automated testing) script.
I'm trying to create a tutorial for how to use it but it is not producing a consistent/accurate script when I repeat a simple user journey. Some actions are being missed from the end script in some instances and then being recorded successfully on another occasion.
This is the issue documenting my exploration on github: https://github.com/dwyl/learn-daydream-and-nightmare/issues/8
Initially I recognised the issue when navigating to a new tab in a test and so I commented on an existing issue on the subject on Segment's repo: https://github.com/segmentio/daydream/issues/31
The issue was first raised by another user in September 2016 and has not received any response so I think it's unlikely they will respond.
- Has anyone come across this problem using Daydream? and did you find a solution?
- Is there a specific action which may be causing this bug?
- Can anyone see any issues in the segmentio code that could be causing this?
Thanks :)
Goolge very kindly offer a sample dataset of Google Analytics data in BigQuery, so you can run some tests before setting up the actual export to BigQuery.
This is detailed at the following page https://support.google.com/analytics/answer/3416091?hl=en&ref_topic=3416089
However when you try to add the project google.com:analytics-bigquery as shown in step 5 of the guide. The following error is shown:
Project IDs may contain letters, numbers, and dashes, with an optional
"domain:" prefix.
As you can see the project ID conforms to this, but you are unable to submit the form.
Google is this just a bug?
Does anyone else have the same issue?
I am confirming - just tried and got the same.
Some-when recently - this dialog form was changed (added options to choose from - display in nav vs. make a current project) and looks like the bug was introduced. previous versions didn't have this bug.
At the same time - confirming that nothing wrong with project name itself - with the internal tool that I am using - I was able to add this project successfully
You should report this bug in BigQuery issue tracker.
Thanks for reporting this issue. We actually already have a fix checked in for this, but we are currently waiting for an opportunity to push this to production, hopefully soon.
In the meantime, you can try one of these workarounds:
navigate directly to the project: https://bigquery.cloud.google.com/queries/<project_id>
navigate to a dataset on the project, which will display it in the left nav: https://bigquery.cloud.google.com/dataset/<project_id>:<dataset_id>
I am a beginner to robotics, and I wanted to program a robot arm to draw a picture on arbitrary objects I present to him.
I do have an Intel Realsense camera, will receive a dobot.cc robot arm next days, and thought about using ROS as a base, moveit for movements and the PCL library for object detection.
How do I connect all of these together? Are there any particulary interesting tutorials that you would recommend? Anything I should try out up front?
Also, I suppose I will need to build custom code for detecting the target object in the point cloud and calculate how the picture should be placed on the object and then use moveit to follow the target path. Where would this code go?
Any help would be appreciated.
Thanks,
Gregor
Meanwhile, I found an excellent book on the topic:
http://www.amazon.de/Learning-ROS-Robotics-Programming-Second/dp/B00YSIL6VM/
I'm curently teaching myself the MVVM pattern.
I've hit my first snag with the concept of messaging.
I know messaging is contained in the mvvm-light toolkit. But I cannot find an example of usage anywhere (no sample projects are provided in the download).
If anyone can direct me to some information as to how to use messaging in that toolkit, that would be ace.
Thanks
I have posted an example of using Messaging here, as part of my Intro to MVVM Light series.
My goal in this example is to send a message indicating that navigation is needed. The VM can't manage the navigation so it sends a message to the view. We do this in three steps:
Create a class to contain the message that is to be passed
In the view model, instantiate the message class and broadcast the message
Within MainPage.xaml.cs register for the message and handle it when received
The complete source code is posted and also available for download.
I found the following article on the subject. The subject line seems a little unrelated but that link is for part 2 of the article and if you read and scroll down a bit you will find info on the RelayCommand, Messenger, EventToCommand, and ICleanup.

Good luck.

Here abit about it.

I posted some simple MVVM Light messaging code on this other question with sample compiled code and explanations.

I am not an expert in flash, but I do work with AS and tweak Flash projects, though not having deep expertise in it. Currently I need to revamp a flash website done by one another guy, and the code base given to me, upon execution is throwing the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at NewSite_fla::MainTimeline/__setProp_ContactOutP1_ContactOut_Contents_0()
at NewSite_fla::MainTimeline/frame1()
The structure of the project is like, it has the different sections split into different movie clips. There is no single main timeline, but click actions on different areas of seperate movie clips will take them between one another. All the AS logic of event handling are written inline in FLA , no seperate Document class exists.
Preloader Movie clip is the first one getting loaded. As i understood the error is getting thrown initially itself, and it is not happening due to any Action script logic written inline, because it is throwing error even before hitting the first inline AS code.
I am not able to figure out what exactly is causing the problem, or where to resolve it. I setup the stuff online, for reference if anybody want to take a look at it, and here is the link. You need to have flash debugger turned ON in your browser, if need to see the exception getting triggered.
I really got stuck at this point. Any help will be great. I had not seen the particular solution I am looking for anywhere yet, though Error #1009 is common.
Did you set the option "Export at frame 1" for the classes in your library?
I get this error for instance:
I have a circle which is a Circle class and put it on Frame 10.
If I try to attach a eventHandler to it from frame 1, I get this error.
Set the option "Export at frame 1" for my Circle class will solve this issue for me.
