I am posting this in case anyone ever has the same issue, they will know how to fix it.
I have a customized version of AP301000 in R2020R2 Build 20.207.0012. The page publishes and works fine.
In the project editor, on my custom field, I entered a LabelWidth with a value of “M”. This caused the page to error. I unticked the checkbox on the LabelWidth propery. The value hRESET] was automatically filled into the value field. I saved the change and tried to preview and I got this error
Steps to try to get rid of the error:
- unpublished all
- deleted the screen from the customization
- published the project
- restarted the application
- cleared cookies from the browser
- added the screen back into the project with no changes.
- clicked preview changes and I still get the error.
I tried this in a different browser, same thing occurs.
I also verified that after deleting and unpublishing, in the project editor, there was NO reference to AP301000 anywhere. I checked this by going to File - Edit Project XML and by going to File - Edit Project Items.
