Resolution: Won't Fix
Affects Version/s: 5.5.5
Fix Version/s: None
If you create a web Panel and leave the “Provider class/script” field empty it will produce an error when you click update:
It appears as though it does not create the web panel but it does which you will see when you go back to the script fragments web panels main page.
Once this invalid web panel has been created any further attempts to update or create other script fragments will result in the same error as shown above.
You have to find the invalid web panels that have no active content in the “Provider class/script” field and delete it so you can then create and update your other script fragments.
Steps to reproduce
1-Create a web panel where the “Provider class/script” field is left empty
2-When you see the error go back to the web panels page where you should see your web panel that threw an error when you tried to create it.
3-Try to create a new "Web item", "Constrained create issue dialog" or update existing ones and you will see the same error. (note: the fragments do still get created)
4-Delete the broken web panel with the empty “Provider class/script” field and then you will be able to update and create fragments again
