Focus on pane deactivates and activates current tool

DirkTillmanns — Tue, 16 Jul 2024 14:45:13 GMT

Hallo,

We have implemented a pane that derives from "TOCMapPaneProviderPane". Any tool is activated in the active map. E.g. "Create a line". As soon as the pane receives focus, the active tool is briefly deactivated and immediately reactivated. The currently active editing will be lost.

This is fatal and makes the pane unusable.

It doesn't seem to be due to our implementation. In the pro user "samples" there is a "TOCMapPaneProviderPane" implementation for which this behavior can also be reproduced.

Any ideas?

Best regards, Dirk

@DirkTillmanns

I tried this with the "ImpersonateMapPane" community sample.

I started an active editing session for a line feature class in my active map view.
I then activated my new Map pane in the middle of the editing session.
When I went back to my original Mapview, I was able to restart my editing session. I did not see the tool being deactivated\reactivated.

Is this similar to your workflow? Just confirming to see what I am missing in order to repro your issue.

Thanks

Uma

@UmaHarano

If you have a CustomTool active and set breakpoints on "OnToolActivateAsync, OnToolDeactivateAsync" and then activate the "Impersonate Map", you can observe the deactivation and activation.

Thanks

Dirk

@DirkTillmanns

Thanks for the detailed steps. I see the issue now. The development team is investigating this one. I will post back when I have an update.

@UmaHarano in 3.5 it did not work, but the error no longer occurs in version 3.6. Thank you.

Unfortunately, our customers can only use the long-term versions.
