Cannot resolve an issue with customized workflow. Error: Could not load validator class

Bohao Cao Sep 13, 2013

Hi folks, I am trying to setup a test server of version 6.0.6. I've imported our customized workflow from another server versioned 5.2 and associated a scheme to it. When I tried to close an issue which project is binded with the workflow, I got the following exception:

Caught exception while attempting to perform action 5 from workflow 10102 on issue 'TEST-2'

I've updated the add-ons to the latest version and installed Jira suites utility, but still got the problem. Any comments or advice is much appreciated!!!

Hi,

Thanks for the reply. We found the problem after all, which does relate to the third party plugin. It turns out our Jira server misses a Groovy script runner plugin, and our workflow was customized such that on resolving the issue a validator script is running. Missing the Groovy plugin the fails the validatiom.

I'd appreciate all the input on trying to solve the issue.

Hi Bohao,

I'm suspecting that the problem may be related to third-party plugins and to this KB article:

https://confluence.atlassian.com/display/JIRAKB/Cannot+Create+Issues+due+to+%27Could+not+load+validator%27+class+Errors

As suggested by the KB, please do the following steps and check whether that will help to fix the problem:

1. Shutdown JIRA instance

2. Download the respective plugin and ensure that they are compatibe and installed properly:

- JIRA Suite Utilities

- JIRA Misc Utilities

- Minyaa Suite

3. Restart your JIRA instance

Hope that was helpful.

Hi,

Thanks for the reply. I've reached that page and gave a try on the solution it recomended. We found the problem later on, though, which does relate to the third party plugin. Turns out our Jira misses a Groovy script runner plugin, and our workflow was customized that such on resolving the issue a validator is running.

Hi Bohao, Can you explain the situation that you are trying to do?

Bohao Cao Sep 15, 2013

Hi Darly,

Thanks for reply. Let me describe the steps to replicate the problem.

1. Create a blank project;

2. Switch the project's workflow scheme to the customized one;

3. Create an issue in this project;

4. Resolve the issue, you 'll see the error.

Hi Bohao, maybe its some plugin that you forgot to implement at JIRA 6
