I want to create my own template and my code is:
#{if _arg.status.equals(models.Status.FINISHED)}
#{doBody /}
#{/if}
When I pass an object reference to my tag its saying its null. If I call in my template its working as described in the docs:
${_arg.status}
The error message is:
Template execution error
Execution error occured in template
/app/views/tags/isNotFinished.html. Exception raised was
NullPointerException : Cannot get property 'status' on null object.
I am not getting any null pointer exception. What I am doing wrong here?
Thanks for your help.
It seems like _arg is not found in the scope you're working with. This seems to indicate you get arg implicitly in the tag. You might try omitting the _arg. from the tag.
I am not getting it really. But today I tried again with _arg and its working now as excpected. It can be closed now.

While multiple lot Allocation I am getting error:
Unable to cast object of type 'PX.Objects.IN.INLotSerialStatus'
to type 'PX.Objects.IN.Overrides.INDocumentRelease.LotSerialStatus'.
First unpublish all customization and try to reproduce the issue.
If it goes away re-publish customizations one by one until you find the one causing the cast error.
Review the code of the customization for all references to INLotSerialStatus and LotSerialStatus. Also look at Acumatica traces to find more details about the error.
A LotSerialStatus object is also a INLotSerialStatus because LotSerialStatus inherits from INLotSerialStatus. This is a valid assignment.
The inverse is not true, maybe there is an invalid assignment for which no cast is possible in the source code of the customization:
I've been plagued for months with an error in ODM.
It doesn't prevent my services from working, it only prevents ODM from automatically generating the JSON input payload when I test a service through the Rule Execution Server (the Retrieve HTDS Description File).
I attached a screenshot of the error.
What is puzzling is that:
if I move my variable from Input to Output, then the JSON gets generated in the Server Response section
if I manually enter my own JSON, the service executes correctly and I get back a decision
Does anyone have any idea what could possibly be wrong here?
Very likely your variable is not being deserialized properly. This would explain both the error you are getting and why you get it only as an input variable.
We get a similar error using a java.tim.ZonedDateTime with ODM 8.9.1, which does not support the java.time package. We just ignore the error -- and are hoping we can avoid it when we move to ODM 8.10.2.
hard to help as some of the context is missing. However the symptoms you describe tells there is a serialization issue one of the class of the HTDS interface.
It could be :
a getter/setter missing
a dependency missing in the XOM (classloader)
or a #jsonIgnore missing on a non getter/setter method whose name starts by get or set.

I have two classes org.my.ClassA and org.my.ClassB both classes are in the same package org.my in the WEB-INF/src in the same database.
ClassA has the method public add(org.my.ClassB newB){...}.
In SSJS I have a code block in which I call ClassA.add(ClassB) which normally works fine. Until some unknown point where the Server can't see that org.my.ClassB === org.my.ClassB and it returns the error (message translated from German maybe looks different in English version):
error calling method 'add(org.my.ClassB)' in java-class 'ClassA'.
'org.my.ClassB' is incompatible with 'org.my.ClassB'.
and it points to my line in the SSJS: ClassA.add(ClassB);
What I tried so far:
First I added the line importPackage(org.my); to my SSJS Code. No luck.
I tried to add another method add(Object newB) and then cast the object to ClassB but same result. The error does not seem to come from the java class its from the SSJS code because it cant find the method with an argument of the type org.my.ClassB. But if I test the object in the SSJS code it returns org.my.ClassB.
Then I tried to add the classpath to all variables in the SSJS block like: var newB:org.my.ClassB = new org.my.ClassB(). But same result after some time the application breaks with the same error.
From my Point of view it got to do something with the caching of compiled classes, or so because if I clear the database everything works just fine again.
Hope someone has a solution on this.
This is a class loader problem.
You can find more details about the issue in the answer from Frantisek Kossuth:

I have a wcf service and i want to pass a string[] through it. I am receiving the below error. Can someone point me in the right direction ?
The error :
There was an error while trying to serialize parameter http://services.csssoftware.com/2.0/ComFacades:arParams. The InnerException message was 'Type 'System.String[]' with data contract name 'ArrayOfstring:http://schemas.microsoft.com/2003/10/Serialization/Arrays' is not expected. Consider using a DataContractResolver or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer.'. Please see InnerException for more details.
If you need more data plese let me know and i will edit the question.
For others who get to the same error, the fix was to add :[ServiceKnownType(typeof(string[]))] in my interface class.

I'm getting an error while trying to load an record through the constructor.
The constructor is:
public Document(Expression<Func<Document,bool>> expression);
and i try to load a single item in like this
var x = new Document(f=>f.publicationnumber=="xxx");
publicationnumber isn't a key but tried making an it an unique key and still no go..
Am i totally wrong regarding the use of the constructor? and can someone please tell me how to use that constructor?
The error i'm getting is:
Test method TestProject1.UnitTest1.ParseFileNameTwoProductSingleLanguage threw exception: System.NullReferenceException:
with the following stacktrace:
SubSonic.Query.SqlQuery.Where[T](Expression1` expression)
Load`[T]`(T item, Expression1expression)
db.Document..ctor(Expression``1 expression) in C:\#Projects\DocumentsSearchAndAdmin\DocumentsSearchAndAdmin\Generated\ActiveRecord.cs: line 5613
rest removed for simplicity
Regards
Dennis
Use == instead of =, i.e.:
...(f=>f.publicationnumber == "xxx");
I've just gotten the SubSonic source, and found out that it had to with the expression parser and my lack of knowledge thereof .. my right side of the expression was actually an item in an string array - and s[PUBNO] (PUBNO is a const) and it was looking for an column named s instead of publicationnumber, i don't know if this i a bug or not in the linq classes
none the less - i've managed to get it to work by creating a local variable containing the value of s[PUBNO] and using that instead...
