I tried to understand the configuration of the form properties but is there a document which describes this?

i found in the example vacation request process the line
<startEvent id="request" activiti:formKey="org/activiti/examples/taskforms/request.form" />i assume that this line allocate a form to the start event.

but when i try to use the same paradigm in the activiti designer the automated code completion removes my change and rearrange the code to the diagram.

also i dont have a formproperty getUser to get the user of the form.

i don't see a way to assign tasks dynamic to different users.

Hi,

Variable-names cannot contain dots when you want to use them in expressions. So "first.user", will actually try to find a variable with name "first" and call "getUser()".

What does the stacktrace in your tomcat say?

this is all kind off pseudocode.
i have no conclusion how i should solve this.
in the expression next.user should acess the user variable. it is not the same as "next.user" which is a string.
also i have no idea what the tomcat is doing.
i just use the designer.

is there no document about user assigment. because all i found is the performer type and expression way.
i works pretty good for predecided workflows but not for a dynamic approach.

I I understand you correctly, you want to fill in a username in a form, and assign the next task to that user?

i found a easy conclusion.

but for this i have to insert the username manually in the prior task.
it would be good if there would be some accessible usertask properties like. get-claimed-user or getuser.

for my momentary situation it works good enough.

Makes sense actually. I think that would be a valid addition.
