connector tag transformer problem

Hello,

I'm trying to setup a connectro to an external cvs repository. Basically the code runs fine but I have some problem when using tag fields.

I tested my code using the "Tags" attribute from the defect workitem. I set up the sync rule to use the workitem tags tranformer and tags were compiled in a space seperated string. So no problems here.

Now I've changed to use customized process of my customer, having a custom attribute of type tag in the defect workitem and I get this exception:

java.lang.ClassCastException: com.ibm.team.workitem.common.internal.util.SeparatedStringList cannot be cast to java.lang.String

I don't have a clue what actually the problem is. Any pointers would be appreciated.

Regards
Joerg
