Drilling and Interactivity across pages
Hi all!
Currently I am developing a custom visual for one of my clients. One of the features that I need is to drilldown on click of a data point. A behavior like the "histogram" default component would be perfect (the user can select data, then if [s]he clicks on "drill mode" can drill down contextual data).
Trying out the sampleBarChart component from the Microsoft's tutorial, I get a strange behavior:
- In PowerBI Desktop everything works as expected.
- In PowerBI Online (IE11/FF/Chrome) it does nothing.
Strangely enough, if I manually force the refresh of the data (by for example resising the visual - edit mode only) I get the right data! For this reason I guess a possible workaround would be a simple refresh... But AFAIK it is not possible to trigger a refresh on a visual by code...
I am attaching a pbix with a dumb dataset to reproduce the issue. I had to enable drilldown on the sampleBarChart visual: I simply added
"drilldown": {
"roles": ["category"]
},in the capabilities and built it.
Can anybody help?

One last note: with the new update of PBI Desktop, the offline behavior matches the online one.

Hi! Thank you for you answer!
Checking thoroughly the behavior of the visual, I managed to get the same behavior using just the drilldown controls (nothing custom at all this time: no selection, no contextual drilldown, no events on my custom visual fired... And no refresh until resize!). It seams to me much more like a bug than a limitation. I made a quick scheme of what the behavior I get and I attached to this message.
As you can see, when I expand to the next level, the controls and the title understand the change and are able to update, but the data isn't. I get no update event (I am logging every event). Moreover, clicking "update" has no effect on the visual (once it gets in that state it is "stuck" there until resize: I get no "update" event), while in a normal situation (and also after resize) I get normal events on "update" as well.
I have written in the "issue" section of this community website this problem, but since last ticket did not have any answer (almost a month old.. ) I am not sure it will be useful...
PS: I also would like to note that (ironically ?!) in PBI Desktop the behavior is reversed (on resize, I get the wrong data!).
