Steps to reproduce:
- create a process application, whereby the containing process has an embedded start form
- deploy the process application to a container
- login into cockpit
- go to the repository view
- select the corresponding deployment
- redeploy the process
- switch to tasklist
- try to start a process instance of the process
The returned context path is null, so that the form key cannot be resolved correctly to load the embedded form.
The REST Api calls ManagementService#getProcessApplicationForDeployment() which will return always null in this context.
