From the stacktrace, it seems some bind variable that is required by your view object query is not being set correctly.
If it works intermittently, it could be that the bind variable is lost at some point. To debug/test, try it with a hard-coded value for your bind variable and see if that works first (if you have a ViewCriteria, try removing that first) - then run the task flow and see if it works consistently.
I would suggest running the application in JDeveloper with -Djbo.debugoutput=console argument. It gives you a lot if information of what your business components are doing and you could catch the error cause in console logs.

I have set a page custom field called CustomLogo in Liferay 7.1. I would like to access its value in Free marker template. After reading documentation & some posts related to it, i used following code to access custom field
<#assign page_custom_field_logo_url = layout.getGroup().getExpandoBridge().getAttribute("CustomLogo") />
<h1>${page_custom_field_logo_url }</h1>
I have set View Permission for the custom field (to all User roles). I have also checked if the column names and values are set properly in the liferay database (expando tables).
However i am getting following error:
FreeMarker template error: Java method "com.liferay.portlet.expando.model.impl.ExpandoBridgeImpl.getAttribute(String)" threw an exception when invoked on com.liferay.portlet.expando.model.impl.ExpandoBridgeImpl object "com.liferay.portlet.expando.model.impl.ExpandoBridgeImpl#f2864c8"; see cause exception in the Java stack trace. FTL stack trace ("~" means nesting-related):
- Failed at: #assign page_custom_field_logo_url... [in template "/templates/portal_normal.ftl" at line 75, column 37]
Upon observing the stack trace , I saw there is a null pointer exception which states:
Caused by: java.lang.RuntimeException: java.lang.NullPointerException
at com.liferay.portlet.expando.model.impl.ExpandoBridgeImpl.getAttribute(ExpandoBridgeImpl.java:219)

at com.liferay.portlet.expando.service.impl.ExpandoValueServiceImpl.getData(ExpandoValueServiceImpl.java:121)
at sun.reflect.GeneratedMethodAccessor1066.invoke(Unknown Source)
As i stated above, i already set view permission for the custom field. I also double checked the key, typos and possible mistakes but no success.
Please let me know if you have any suggestions or things i missed out. Thanks
Try to get the expando bridge from the layout instead of the group, so
layout.getExpandoBridge().getAttribute("CustomLogo")
should work.
I am trying to get a set of the distinct values of an object's field stored in a Hazelcast map.
This line of java code:
instructions.aggregate(Supplier.all(value -> value.getWorkArea()), Aggregations.distinctValues());
has the following stacktrace :
java.util.concurrent.ExecutionException: com.hazelcast.nio.serialization.HazelcastSerializationException: java.lang.ClassNotFoundException: com.example.instruction.repository.HazelcastInstructionRepository$GeneratedEvaluationClass
com.hazelcast.nio.serialization.HazelcastSerializationException: java.lang.ClassNotFoundException: com.example.instruction.repository.HazelcastInstructionRepository$GeneratedEvaluationClass
java.lang.ClassNotFoundException: com.example.instruction.repository.HazelcastInstructionRepository$GeneratedEvaluationClass
If I were to try this line :
instructions.aggregate(Supplier.all()), Aggregations.distinctValues());
or:
instructions.aggregate(Supplier.fromPredicate(Predicates.and(Predicates.equal("type", "someType"), equal("groupId", null),
Predicates.equal("workArea", "someWorkArea"))), Aggregations.distinctValues());
It just works ... It seems to be something wrong when I am making a reference to the object's field. (I also tried it with other fields of the object and the same error gets returned)
This is running on my local environment and I am sure that the objects are being placed correctly in the Hazelcast map since the other aggregations/predicates are working.
Do you have any ideas about what am I doing wrong?
Many Thanks!
EDITED: So the problem is the closure. It's not available on all nodes. Only on the calling node.
Also. This feature is deprecated. Plz use the fast-aggregations instead.

Any quick solution to avoid these errors on server?
This is, in fact, a server issue. Take a look here or google it to fine-tune your server.
Occasionally the UnhandledException handler in my app is raised due to an unhandled XAML exception.
The UnhandledExceptionEventArgs contains the message
E_RUNTIME_SETVALUE
and an inner-exception of type ArgumentException
Value does not fall within the expected range.
There is nothing in the call stack other than InitialiseComponent() which I can step into/ over without any exception being thrown.
Any ideas on how to debug further or any experience with E_RUNTIME_SETVALUE issues?
I do remember I had to once add basically no-op value converters to some XAML so I could see what was going on and trace the error. That might help in this case as well.
Also try to turn on mixed-mode debugging to see if more data comes from the native stack.
I had this in UWP and it was because I was using OnIdiom
<OnIdiom x:Key="MyFontSize" x:TypeArguments="x:Double" Tablet="28" Phone="16">
</OnIdiom>
I didn't have desktop included in one of the values and I was running my app on my desktop.
WHen I start VS2012 I always get an exception tellng me to look at ActivityLog.xml. Here is what I see- useless to me. Hoping someone else has seen this before.
Also - VS2012 eats 100% of the CPU on the machine at time. Hoping the two are related and fixable.

Is your VSCommands extension up to date?
There was a compatibility issue which could produce similar stack trace, and it was fixed in latest release.
