Seeing this in the wild in our application, but cannot reproduce on the bench. Stack trace below.
Asking here because this seems to be the primary support forum for HERE maps.
I haven't been able to find anything on the HERE maps website or other SO questions that point to this same issue, so just curious if HERE support would like to chime in.

It seems like LiveData source has some null values. the array or variable that collecting the data does receiving null values and it hasn't been handled at your end. The error says null pointer exception for the reference. It doesn't seen coming from the mSDK premium. can look further if code snippets could be shared.

I am using
react-table#7.7.0 and
#types/react-table#7.7.9
Together with react-table-config.d.ts
from this answer.
In my project, I have a table that uses the useExpanded plugin and works perfectly. But when I add useRowSelect and toggleRowSelected is called it crashes. I tried to create a simple example of that error with js but I couldn't.
Things I tried:
Setting selectedRowIds manually using the initialState of the
table works.
Adding the useGroupBy plugin doesn't help. I thought it might help since the error is related to isGrouped.
Using toggleRowSelected(rowId) instead of row.toggleRowSelected() doesn't help.
The error message:
Uncaught TypeError: Cannot read properties of undefined (reading 'isGrouped')

Here is the codesandbox (doesn't recreate the problem)
I have a constraint that crashes in the latest OptaPlanner 8.0.0, but used to work fine on 7.46.0.
As expected, IntelliJ's code inspection (and the debugger) shows that after the first join, the stream is a TriConstraintStream. The runtime class makes more sense to me than the class OptaPlanner is trying to cast to.
When leaving out the last groupBy the error goes away, so that clause seems to cause the issue.
Did something change in the way join and groupby worked?
It seems that the underlying OptaPlanner code was refactored for 8.0.0, so I have trouble seeing what exactly changed in OptaPlanner.
Should I add something to ensure that a TriJoin is used instead of a BiJoin?
I could not find any relevant notes in the migration documentation.
protected Constraint preventProductionShortage(ConstraintFactory factory) {
return factory.from(Demand.class)
.groupBy(Demand::getSKU,
Demand::getWeekNumber

greaterThanOrEqual((sku, weekNumber)-> weekNumber, Demand::getWeekNumber)//TriConstraintStream

.groupBy((sku, weekNumber, totalDemand) -> sku,

sum((sku, weekNumber, totalDemand) -> totalDemand.getOrderQuantity())
)//TriConstraintStream
.penalize("Penalty", HardMediumSoftScore.ONE_MEDIUM,

[edit] For completeness, the new function as suggested by Lukáš Petrovický
protected Constraint preventProductionShortage(ConstraintFactory factory) {
return factory.from(Demand.class)
.join(Demand.class,
equal(Demand::getSKU),
greaterThanOrEqual(demand -> demand.getWeekNumber()))
.groupBy((d, d2) -> d.getSKU(),
(d, d2) -> d.getWeekNumber(),
sum((d,d2) -> d2.getOrderQuantity())
)
...
[/edit]
This was an unfortunate bug not caught by the existing test coverage.
The fix is aimed at OptaPlanner 8.0.1, incl. test coverage improvement.
That said, I would argue that the constraint is not very efficient. Unless I'm missing some key implications, the following is semantically very similar, yet much faster:
protected Constraint preventProductionShortage(ConstraintFactory factory) {
return factory.from(Demand.class)
.join(Demand.class,
equal(Demand::getSKU),
greaterThanOrEqual(demand -> demand.getWeekNumber()))
.groupBy(..., ..., sum((demand, demand2) -> ...))
.penalize("Penalty", HardMediumSoftScore.ONE_MEDIUM);
}
Note how I eliminated the first use of groupBy(). There may be some difference though in how many tuples are penalized this way, which may or may not be what you want. Feel free to open another question on that.
I'm using ArangoDB 3.4.2 and I have a weird problem that I'm not able to explain...
I create a graph (myGraph) in the following in arangosh:
var graph_module = require('#arangodb/general-graph');
var myGraph = graph_module._create('mygraph');
myGraph._addVertexCollection('vertexes');
var edges = graph_module._relation('edges', ['vertexes'], ['vertexes']);
myGraph._extendEdgeDefinitions(edges);
Being vertexes and edges the collections for vertexes and edges, respectively.
Now, I create two vertexes:
db.vertexes.save({"name": "A", "_key": "A"});
db.vertexes.save({"name": "B", "_key": "B"});
So far so good. But now I try to create the edge between both and I get a fail:
127.0.0.1:8529#myDB> db.edges.save("vertexes/A", "vertexes/B", {"name": "A-to-B"});
JavaScript exception: TypeError: Cannot read property 'save' of undefined
!db.edges.save("vertexes/A", "vertexes/B", {"name": "A-to-B"});
! ^
stacktrace: TypeError: Cannot read property 'save' of undefined
at <shell command>:1:9
It seems that db.edges is undefined:
127.0.0.1:8529#MyDB> console.log(db.edges)
2019-01-26T19:01:52Z [98311] INFO undefined
But now, if I run db._collections() it seems that db.edges gets defined (weird!)
127.0.0.1:8529#MyDB> db._collections()
...
127.0.0.1:8529#MyDB> console.log(db.edges)
2019-01-26T19:02:58Z [98311] INFO [ArangoCollection 16807, "edges" (type edge, status loaded)]
and in this moment, the db.edges.save(...) operation works:
127.0.0.1:8529#MyDB> db.edges.save("vertexes/A", "vertexes/B", {"name": "A-to-B"});
{
"_id" : "edges/16899",
"_key" : "16899",
"_rev" : "_YGsKKq2--_"
}
Why db.edges is undefined at the first save()? Why a show colletions operation (which I understand is read-only) is getting it defined? Maybe I'm doing something wrong?
When executing db.edges.save() an internal cache is accessed. If this cache is clear, executing db.edges.save() works to save an edge. Since db._collections() resets this cache, it is possible to run the command afterwards. However if this cache is not clear, an error is thrown as you observed.
The correct and safe way is to access the collection via db._collection("collection-name").
Therefore you can use the following command to save an edge in the edges collection:
db._collection("edges").save("vertexes/A", "vertexes/B", {"name": "A-to-B"});
First of all, I am running V4.2.e Community Edition.
I have the following webscript/free marker template(ftl) to retrieve aspects from a certain node,
[
<#list node.aspects as aspect>
${jsonUtils.toJSONString(aspect)}<#if aspect_has_next>, </#if>
</#list>
]
with the following js part:
var docid = url.extension;
model.node = search.findNode(docid);
It works perfectly. It returns something like:
[
"http://www.alfresco.org/model/content/1.0}titled"
]
but I want:
[
"cm:titled"
]
In the following ScriptNode API I found a similar function called "getAspectsShort":Alfresco Community 4.2 Documentation - Script Node
Obviously there are backend functions in the java classes:
ScriptNode.java
My tried to use it in the following way:
[
<#list node.getAspectsShort as aspect>
${jsonUtils.toJSONString(aspect)}<#if aspect_has_next>, </#if>
</#list>
]
and found the following message in the catalina.out:

Any help will be appreciated,

Hi you're referring to the JavaScript API but you're using the Freemarker objects to retrieve data. So not all the JavaScript methods are implemented in Freemarker.
So use the node.aspectsShort in your JavaScript controller and pass the value to the model object to the Freemarker template.
Here is the reference wiki of the Template node API
And the reference in the docs
You can use shortQName
${shortQName(jsonUtils.toJSONString(aspect))}
http://docs.alfresco.com/4.0/index.jsp?topic=%2Fcom.alfresco.enterprise.doc%2Freferences%2FAPI-JS-Utility-shortQName.html

I get exactly the same error even when I use the code example straight out of the documentation (com.aviarc.dataset:1.1.0):
<workflow xmlns:ds="urn:aviarc:xmlcommand:com.aviarc.dataset">
<ds:dataset-proxy dataset="ds" proxyname="dsproxy">
<set-current-row dataset="dsproxy" position="2" />
<set-field field="dsproxy.email" value="test#test.com" />
</ds:dataset-proxy>
</workflow>
Turns out that the documentation is wrong, as proxyname is not a valid attribute on dataset-proxy. I didn't see it at first (because of the huge stack trace) but I was also getting this warning:
Unknown attribute 'proxyname'
The correct attribute is name, not proxyname. Changing this resolved the error.
