[mapguide-users] Problem in the GenerateFilter() method of theMgSelection class

[Bruno Scott]

I've just made some test on version 2.0 and 2.01 and the bug is still there

I've gone further on my test

I have the same problem on a polyline layer using the PostGIS provider
I have another application using the AUtodesk.oracle provider and i have a
similar problem
but it is not the ids (248, 249, 250, 251) + the magic number (256)
but 255 + the magic number (256) s0 can't get selection on ids
255,511,767,...

I can reproduce the problem on a polyline table on the same database
neither on a x,y table using odbc provider
