Children: duplicate children added: when using pie-chart and dynamic rendering about cljfx HOT 3 CLOSED

Hey, I also answered you here yesterday.

In my case the count can be the same but be different data, would it be bad just to pass in the current data as the key so its unique

It's fine, you can pass the whole data instead of just the count. The resulting view should be the same. The only downside of that approach is a slightly increased garbage collection pressure since the pie chart node will be re-created on every datapoint change. The bug with the chart only appears when cljfx modifies a pie charts' data list, and that only happens when there is a different count of pie chart datas. If the count is the same but the values are different, only changed pie chart datas are updated, but not the list. Because of that, using count is enough with ext-re-create-on-key-changed, but of course, you can use the whole data structure instead of just its count if you want.

Hi, this looks like a known JavaFX bug, there is a workaround described here. Does it help?

Awesome, yeah that worked. I initially looked at that post but the context didnt not immedielty stick out to be to be the same issue, guess it was.

Thanks for the solution. A question on the :key, the example uses a count. In my case the count can be the same but be different data, would it be bad just to pass in the current data as the key so its unique? Or would making it a checksum of the data be better?

Appreciate all the help, just finished my first program with cljfx in under 2 days! and it was a pleasure to use and made things easy to use and fast to implement.
