Hi all,
i'm using java mapscript from ms4w and i try to query a layer with
inline feature (no direct data source).
I get the correct count of results from a querybyrect but i can't get
the feature and it's values. This is because the resultCacheObj has an
index of -1. So it is not possible to use the getFeature. The getFeature
works for the inline features if i use a possible index like 0.
Any hint / solution?
Best regards
Norbert
