Unexpected error: could not save model

[arodriguezmar]

Hi, I am new on using Activiti and I am trying to créate my first process but I don´t know why when I click to save my model it appears the following error "Unexpected error: could not save model" and I cannot do anything.

If I open another already deployed model that you can find as examples and edit it the model, it Works, I mean I can save.

Please, what am I doing wrong?

I am using tomcat-7.4.0 and activiti-5.19.0.2

Hi,

Is there any stack trace in the logs?

Hi,
thank you but it was solved just restarting the server and now I can save the models.

I attached the log so that you can check it in case it happens again.

Thank you

I am experiencing the same problem. It happens with IE11 only. When I use Firefox it works fine.
