Workflow Exception

[venu.vijayagiri09]

Hi,

I am trying to execute workflow in OpenKM 6.2 on windows(with tomcat).
Deployed the process successfully using Jboss Developer Studio.
My form has to pass between two users. I am able to get the form for the first user but it's not going to the second and it's giving the following exception.

Code: Select all

The operation executed by workflow take a lot of time to be executed ?

Thanks for your reply,
Is there any procedure to solve this problem?

[jllort]

We discovered some bug related with this problem, that when application is using systemToken can appear this problem ( not always but in some special cases can happens the problem you related ). We're working to solve it in source code.

Hi, it works ONLY if you configure OpenKM for MySQL (I dont test it with porstgres), with default HSQL not work.

We do not recommended HSQL for production.
