Hello,
currently i'm working on my E4 RCP application with the GeoTools repository
completely cloned and in my workspace. So i'm using the most recent version
of the SWT module (24-snapshot, where no official release is out as far as
i know). And i ran into a bug that some others apparently also had in the
past. See here:
https://osgeo-org.atlassian.net/browse/GEOT-6277?attachmentOrder=asc and
https://sourceforge.net/p/geotools/mailman/message/36741424/
I can add the swtMapPane into a part. Loading shapefiles works fine without
problems. I also can load a WMS. But as soon as i toggle the visibility in
the layer view, or use the zoom extent option twice in a row, i get the
same error as in the links above.
Did someone solve this problem already? Or is it still unknown, why it
happens?
I'm aiming for a contribution later that year, for the swt module. Any
suggestions, what in this module causes the error, so i can have a look at
it and hopefully fix it?
First thing i want to try is using JAI EXT (or should i use ImageIO EXT
instead?). Do i need to turn it on in my own code, or in the swt module
code?
Any other ideas where to look at and what to try?
Thanks in advance,
Jones
