Could you verify that if you fill-in a description that it works?
Then it's definitely a bug.

If you mean description of process … then I tried but it doesn't work any way.

Thanks.

Dear All,
I made another try … I exported the model process (included in the distribution), and then reimported the xml. I can correctly deploy this new process, but if I open the imported model and then try to save it (even without modifying it) I get the same error.

Can anyone please suggest a solution ?

Thanks.

Best,
Andrea

Hi,

If you fill-in a description do you get a different stacktrace?
Are you using the Modeler that's included in the 5.11 release?

Hi,
thanks for your reply. Yes the very same stacktrace … I think this is something related to grants, I made this try :

1. create a new model accessing activiti-explorer from a browser window on the server itself. Saved and everything went ok.
2. accessing this model from a browser on a different machine tried to save without modifying and get always the same error
3. reaccessing the model from the server itself tried to save and again everything went ok.

Do I have to configure some particular policies fro tomcat ?

Thanks again.

Best regards,
Andrea

Hi,

This works fine here. So no problem working from another machine.
Could it be related to your network?

I'm checking firewall settings …

Hi,
solution found. Firewall (JUNIPER) was blocking the request since the signature was associated with a directory traversal attack. Since this is a default rule for many firewalls maybe it should be avoided to use the ../ in the post uri from editor.

Thanks.
