Hi, I have implemented a function that reproject vector layer when I change map SR. The feature are now redrawed correctly. But now there is another problem: 1 - light on vector layer 2 - change mapSR (sr1) -> layer is reprojected 3 - light off vector layer 4 - change map SR (sr2 - different from previous) 5 - light on vector layer -> layer not appears onto map (I presume because layer have feature stored in sr1 system and the map is in sr2 system)
How can I fix this problem? I have to reproject features also on set vector layer visibility? Thanks.
