Custom Matrix Visual - Expand/collapse row headers problems
Hello, I've been having some trouble figuring out how to do expand and collapse on row headers of my custom matrix visual. I've followed the guide on your docs here but buttons don't all work. I'm rendering a button for nodes where node?.isCollapsed != undefined, meaning it should be expandable/collapsable. However, I cannot get this to work for deeper levels than the first. Comparing the default matrix visualization, the buttons are rendered correctly. Therefore I suspect it has something to do with the creation of SelectionId of the inner rows. This is where I just can't figure anything out because the documentation on SelectionId for matrices is lacking. In image, button for "Resultat" works, "Driftsresultat" within does not. Can I get some help identifying the issue? Debugging selectionId is not fun, wish its api was open.
Matrix visualization row not showing expansion after data model update
We have a published report which contains a matrix visualization. The rows control now contains three fields; when initially published it contained two. The third row field is a calculated concatenation field which had not been created at initial publication. Via the URL that end-users use, the first row expansion (displaying field two) works fine and has always worked. Field two values show an expand/collapse icon, indicating that the report knows there is a third field to expose. However, when the expand/collapse icon is clicked no new fields/rows are exposed even though the status of the expand/collapse icon changes. I have refreshed the report and its associated semantic model. I have cleared the browser cache. In Power BI desktop everything works as designed.
