AW: [udig-devel] ShapeType changed illegally from Point to Undefined

[Schneider, Michael]

Hi,
 
I'm sorry to say so, but it seems to be worse with RC 5. I now use the
download from today (RC 5) as stand-alone, and the RC 4 SDK version, so
I can compare them directly.
 
Using shapetype Multipoint: RC 5 only shows one of three points in the
shapefile; with the same shapefile RC 4 shows all three.
Using shapetype Point with 3 records: RC 4 shows all when all 3 are
visible, but after zooming shows only one when 2 should be visible. In
contrast RC 5 only shows 1 when all 3 are visible and when zooming in so
that the one which is shown stays visible, it disappears!
 
Michael

Hi, 


I remember trying to fix a related problem.  It occurred when a new
shapefile is created then points are added to the file.  Try uDig 1.1RC5
and see if this problem is fixed.  If it isn't let me know and I will
make sure I can fix it.  




I'm quickly having a look at the code right now to see if there is any
obvious problem.

	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:
