Automatic Assigment

[tschernonoll]

Hi All,
i try to automate the assignment of a task by the engine.
i have a very easy task where a user enters some information. when the user commits the form he should get a new task where he can check if the informations are valid or not. if they are valid the task ends if not he get back to the enter information task.

Click in the property-panel on the right, on the tab "Form" (under the currently selected "Main Config")

thx for the fast answer. is there a document abut the usage of the form propertie configurator or a basic example?
because i have no idea how to use this tool.

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

Hi,

In the user guide this is explained very nicely:

http://activiti.org/userguide/index.html#formProperties

Best regards,

i can choose between two users kermit(the admin account)
and a new user stud1

as you can see i have a formproperty user which is a string type variable and should hold the next user.

when i start a process instance i get this exception

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?

[tschernonoll]

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?
