Error creating issue: Could not load validator class

We have created a custom issue type and a custom workflow. We have tried to create a new Issue in that project which is associated with these, but we get this error message when clicking on Create button:


Error creating issue: Could not load validator class


In the logs we have the following stacktrace:

We don't know what to check, what is wrong with the current configuration. Please assist us to resolve this problem.

Thank you

Thank you guys for the tips. It turned out that something went wrong with the workflow's "Linked Statuses", so when I re-created the workflow and set the statuses well, it was working fine.

What validators do you have on the workflow transition that is failing?


The stacktrace says:

What should I check? I have all permissions on the project.

You need to look at the workflow. What validators are set on the transition?

Hi, in the initial-actions tag I have:

        <validator name="" type="class">
          <arg name="">
          <arg name="permission">
Create Issue

Hmm, now, if that is the only validator, I'm a bit stuck because it's the standard one that you pretty much need in the workflow and is part of the core, so I'd expect it to work. Need to cast the net a little wider:

Are there errors above and below the error you have posted?

How did you create this workflow?

In the logs there are no other error messages.

Actually I have inherited this workflow from one off my ex-collegue, so I don't know how it is created.

In that case, I'd be tempted to start with a clean workflow - set up the same status and transitions and test with that.

Hey there, Miklos.

Please look a the following KB:

Hope it helps.

Warm regards,



I already have seen that but we don't have "IssueNotFoundException" messages, so I don't think it's applicable to us.
