Modify WorkItem status from within WikiPage

[stefanWildmoser]

Hello,

I would like to know a way to modify the status of a WorkItem from within a WikiPage via script (Velocity). I think I can not change the value of the status field directly because of the workflow. So maybe I have to use the function "getAvailableActions". I found Java code which does this job but I have no idea how to do this via velocity code.

Any velocity code known to solve this issue?

Many thanks, Stefan
