Exception in PicLayer with autoloaded calibration

[alv]

What steps will reproduce the problem?

1. Calibrate a picture, let josm save the calibration on exit
2. Restart josm, load a bit of data
3. Reopen the previous picture file, (let it reload the calibration if it asks)
4. Activate the piclayer layer
5. Exception (see end for that), ignore it
6. select the "Drag or create point on the picture tool" (the picture does not have previous control points)
7. Don't add any calibration points. Drag the map view with a left click-drag.
8. Exception in plugin PicLayer.

In version r4806 the exception at step 5 never happens, in r4869 it always does for the first activation. The step 8 exception happens in both, and as many times as you drag. If you add a point in step 7 or after step 8, it doesn't (anymore).

This is for the exception at step 8:

[skyper]

The step 5 exception looks very similar to #7312 introduced with [4822].

[Larry0ua]

also strange thing is that mouseReleased is called when mousePressed not (exception should not happen without it) - and user even did not click on the view. very strange...

[Larry0ua]

I fixed NPE at [o27435]
Waiting information from the creator if that is resolved

[alv]

Both exceptions are now history, with the latest plugin and [4870] josm. Closing.
