How to get WCTypeInstanceIdentifier for the object?

[VasiliyRepecki]

Hi.

How can i get WCTypeInstanceIdentifier for the object (e.g. WTChangeOrder2 instance) by java code?

Thanks.

[VasiliyRepecki]

I am trying to use TypeIdentifierUtility.getTypeInstanceIdentifier(object) method.

The result looks like WCTYPE|wt.change2.WTChangeOrder2~~WCI|453083|20|453082

And I have an

NullPointerException

at com.ptc.core.lwc.server.LWCNormalizedObject.set(LWCNormalizedObject.java:567)

when i try to set this WCTypeInstanceIdentifier to the attribute.

Attribute is created based on global attribute, which defined as Reference type.

What am i doing wrong?

Hi,

Maybe this will work:

TypeInstanceIdentifier obj = TypeIdentifierUtility.getTypeInstanceIdentifier(yourObj);

if(obj instanceof WCTypeInstanceIdentifier)

{

WCTypeInstanceIdentifier obj2 = (WCTypeInstanceIdentifier) obj;

}
