Just some precisions : - I spent lot of time trying everything (taskInstance, processIntance and not only token) in my expressions and I never get any answer. I don't know why since it works well with any simple variable (with "#{var['myvar']}"). - This input code is in a modified form file created by the GPD. I need to have 2 solutions here : the first is a normal transition link and the second the file upload. They lead to the same unique transition to the next node. I searched the documentation and I understand that the way I do it should work.. is it a bug? (I'm not know EL enough to figure myself) I searched in all the test cases and I didn't find any example of that... did I miss one? I lost nearly a day on that so if you have any little idea... even if it may seem stupid... I'll take it and test it.
