Problem after Model Reimport

94 Views

Hi All,

I am desperate. I keep receiving the following error message:

java.lang.IllegalArgumentException: Must not add role listener with role null

    at com.sap.tc.webdynpro.modelimpl.dynamicrfc.DynamicRFCModelClass.registerRoleListener(DynamicRFCModelClass.java:1395)
    at com.sap.tc.webdynpro.progmodel.context.RelationElementList.<init>(ElementList.java:1871)
    at com.sap.tc.webdynpro.progmodel.context.DataNode.createRelationElementList(DataNode.java:201)
    at com.sap.tc.webdynpro.progmodel.context.DataNode.doSetElements(DataNode.java:180)
    at com.sap.tc.webdynpro.progmodel.context.Node.setElements(Node.java:318)
    ... 127 more

I have done 2 things since then:

1. I reimported the model

2. I refactor->renamed some methods

I guess it is the following line of code that causes the exception:

wdContext.currentZ_Read_Infoobject_InputElement().modelObject().execute();

Anyway, I have no clue where the comes from.

Any anybody give me a hint??

THANKS, Johannes
