Custom extensions causing Invalid Viz error on tabbed container objects?

danelooman — Mon, 09 Nov 2020 21:34:51 GMT

I have made a handful of extensions for my company and recently we have noticed a pattern that custom extensions cause the tabbed container to break. Has anyone experienced this before? Attached is a screenshot of the error and a copy of one of my extensions that can cause the error.

Try changing the first line of your paint method to:

var app = qlik.currApp(this);

Also instead of calling app.getList('Field') it's better to add a qFieldList to your initialProperties. I have written about this here:

Hope this helps!

@ErikWetterberg thank you so much for your time and suggestions. I am working on implementing qFieldList and have added it to my initial properties. Would you have a moment to show me how to access those in a drop down in the definition? I am only concerned with the qName as both a value and a label but I can't quite get it to work.

Implemented the changes to the best of my ability and am still getting random invalid viz errors with no console error. Attached is a different extension that may also be related.
