After an update from 2.7 to 2.10 the Query Widget in the developer UI throws a few bugs. 2.7 Icons are missing. When I click on each query the error below is thrown: Cannot read property 'name' of null.
I am editing from the configs\Query folder
Phil,
That is really strange. I tried to duplicate your scenario by changing my query widget icon in the config file to "" and I did get the error about not being able to find default_task_icon.png but it allowed me to choose a simple marker symbol and save with no issue.
Did you upgrade in sequence from 2.7,2.8,2.9,2.10?
I believe so.
I ended up tearing down this widget and starting over again.
So it is working now?
Glad to hear it.
