No Starting Form

[swa1]

When I want to start the process with a click on "Show Start Form", the popup which should show the form just shows "Failure" and the Ok-Button.
The form is there and it is a correct HTML file. Anybody an idea what problem this could be?

[frederikherema1]

What does the log-file say?
Can you double-check the form has the same name as the name you use in the activiti:formKey?

[swa1]

The form name is the same.

The log-file says:

What's the name of the form-file, and what activiti:formKey are you using on your start-event.
There seems to be a mismatch, or maybe the form isn't found within the deployment.

[swa1]

This is the start event:
<startEvent id="StartNoneEvent" name="StartNoneEvent" activiti:formKey="emailAbrufen.form">

And the form-file is emailAbrufen.form as you can see in the screenshot.

Swa,

Is the form-file deployed alongside the process-definition in your business-archive (.bar file). Can you check (using probe or DB-tool) that the deployment that holds your process-definition (ACT_RE_PROCDEF_ .DEPLOYMENT_ID_) contains 2 resources (ACT_GE_RESOURCE_), one form and the other your process?

[swa1]

Ah yes, that was the problem. The form wasn't there. Thanks a lot.
Now it works.

i have checked the datebase. the form has already deploy .But I still get the error. why?

[jbarrez]

Are you referecing the form in the right way? Ie if  your form lives in a certain folder in the .bar file, you must also make sure that folder structure is mimicked in the form attribute.
