#1456 isArray returns true for method parameters of type reference

No
On the result of a getClass operation for class CIM_ControllerConfigurationService, the parameter job of method HidePaths returns true for isArray, but parameter job is not an array.
For easier reading, here is the XML representation of parameter JOB in method HidePaths of class CIM_ControllerConfigurationService:
<PARAMETER.REFERENCE NAME="Job" REFERENCECLASS="CIM_ConcreteJob">
<QUALIFIER NAME="IN" TYPE="boolean" OVERRIDABLE="false" TOINSTANCE="true">
<VALUE>
FALSE
</VALUE>
</QUALIFIER>
<QUALIFIER NAME="OUT" TYPE="boolean" OVERRIDABLE="false" TOINSTANCE="true">
<VALUE>
TRUE
</VALUE>
</QUALIFIER>
<QUALIFIER NAME="Description" TYPE="string" TOINSTANCE="true" TRANSLATABLE="true">
<VALUE>
Reference to the job if 'Method Parameters Checked - Job Started' is returned (MAY be null if job completed).
</VALUE>
</QUALIFIER>
</PARAMETER.REFERENCE>
hello Robert:
I looked at the code and was unable to recreate it in my test env.
Can you please let me know the steps to recreate the defect., is it possible for me to test it in your environment.

Hello Robert:
As discussed today, I confirmed that the sfcb.1.3.2 does have CIM_Schema 2.17 loaded. the getclass() operation works for other classes but not for "CIM_ControllerConfigurationService" with this cim-om in my test env. Do I need to have any particular provider installed to work with this class.

Hello Robert:
I am able recreate the defect using Pegasus cim-om.
For Method "DetachDevice" and "PARAMETER.REFERENCE NAME="Protocol controller" isArray is returning "false" but
for Method "HidePaths" and "PARAMETER.REFERENCE NAME="Job" isArray is returning "true"
and I am investigating the problem
Thanks and Regards

Hello Robert:
It looks like the response sets the cim element as PARAMETER.REFERENCE but returns an arraysize of "0" for this CLASS="HidPaths" and
<PARAMETER.REFERENCE NAME="Job" REFERENCECLASS="CIM_ConcreteJob">
which indicates it is a unbounded array.
At this point It is not clear if the server should return a PARAMETER.REFARRAY or the server should not return the array size if it is a PARAMETER.REFERENCE for this element.
Thanks and Regards

Hello Ravi,
thanks for your investigation. But I can't really follow your analysis. I am checking the XML that is returned by the CIM Server for class CIM_ControllerConfigurationService, but the method parameter in question is exactly what I have listed in this bug report. And there is nothing of an arraysize=0 in that XML.
Where do you think the response from the Server contains the data that leads to arraysize=0?

Hello Robert:
ParameterReferenceNode and ParameterRefArrayNode both were using the same const. PARAMETER_REFERENCE in their constructor, and ParameterReferenceNode was being resolved as ParameterRefArrayNode, and as the ARRAYSIZE attribute was null for this element, this was setting the arraySize=0.
I have uploaded the patch with the fix. Can you please try this in your environment.
Thanks and Regards

Ravi,
I have tested your patch and it works perfect in my environment, including a couple of other regression tests I have for the JSR-48 Java Client on z/OS.
Thank you for the quick turnaround.
