Will do...
169453: Eliminate children of RepositoryTaskData and make final

Rob,
thanks for the info. I have eliminated my own ...TaskData and use
RepositoryTaskData and store all the needed
info in RepositoryTaskData Attributes. That fixed the problem (it took some
time to refactor it properly 8-).
I think, that BugzillaTaskData are confusing and should be eliminated (and
make RepositoryTaskData final as Eugene suggested),
so other connector developers are not tempted to do what I did.
Thanks for your help, Lubos
