So I’m trying to migrate from JBPM to Camunda with a simple process. So for I got the engine working, process is starting but I don’t know how to make the form open, in detail, when i press the button that should start the process insinde my web app, everything works but can’t figure out how to open the form without the task list from camunda web app. Thank you in advance!

Hi @floris,

Using embedded html form, you can’t open it outside the tasklist app “that is why it is called embedded”.
You have the option to use external forms instead which fits your requirements.

Yes you can…
Below is an example for using JSF forms as external forms

# External Task Forms

This quickstart demonstrates how to use Java Server Faces (JSF) forms as [External Forms][5]. External Forms can be loaded from your app and started via the camunda Tasklist:

The JSF form is rendered in a new window.

The following is the source code of the JSF form used to start the process (the one in the screenshot displayed above):

Hi @hassang,
I am trying to use External forms.I will Just Give my scenario: I am having 2 user tasks one after the other which uses the external forms.So i have 2 challenges:

Can i access the form without using the task list.As at each time the external form has to be opened from the task list. I just want the form to directly be accessed without using the Task list.

2)If there are 2 user tasks one after the other(or any other service task in between) after the first user task finishes can it open the external form of the next user task without going to the task list and opening the external task from it manually.

Thanks,
