"Center view" button greyed out in Geotagged Images pane

[bartosomail@…]

What steps will reproduce the problem?

1. It happened a few times, always while I was working at image postition adjusting. I still haven't find a way to deliberately reproduce the problem.

What is the expected result?

the "Center view" button should never become greyed out

What happens instead?

I erratically find myself with the "Center view" button disabled (greyed out) in the Geotagged Images pane.

Please provide any additional information below. Attach a screenshot if possible.

Restarting JOSM makes the button available again.
I suspect the plugin photoadjust might be involved, because i first noticed the issue after I updated it to Version 31953.

This happens when a data layer is active and the PhotoAdjustMapMode (image with arrows in the left pane) is active. It works if a geo image layer is active. The problem is that no mouseReleased() is called while the data layer is active. The according MouseAdapter was added with Main.map.mapView.addMouseListener(mouseAdapter);. I get the mouseReleased() if a geo image layer is active. Is someone reading this who has an idea why mousePressed() is called but mouseReleased() not?

[holgermappt]

Problem found: mouseReleased() is missing in PhotoAdjustMapMode. I will fix it tomorrow.

I added the missing mouseReleased() in [o31962]. Please try plugin version 31963.

The Center view button is disabled (grayed out) while a photo is moved. This is necessary to move a photo if the center view is active, see #11908. The Center view button is enabled again if the mouse button is released.

Ah, now I understand why I couldn't replicate: I always used the shift+click for image repositioning, but I must have occasionally dragged a picture unintentionally. Working fine now, thanks for the fix!
