Hi,
as you know meanwhile I'm working with shapefiles and marks in uDIG.
Marking several points using a shapefile you have two possibilities:
1) Use a shapetype of multipoint with one record of all the points (that's what I did up to now) - drawback: you only have one item in the feature info table.
2) Use a shapetype of point with one record for every point - then you have number of point items in the feature info table
But when I do it the 2nd way I encounter the following problem:
When all the points are shown it is fine, but when I pan or scale so that at least one point is not visible anymore all but 1 dispappear, although there should be more than 1! By the way: the feature info table still shows all points.
This does not happen when working with a MultiPoint shapefile.
That's the exception I got:

Any ideas?
