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   Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von Jesse Eichar Gesendet: Mittwoch, 8.

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: !ENTRY net.refractions.udig.project 2 0 2006-11-08 11:03:47.902 !MESSAGE Problem beim Rendern:ShapeType changed illegally from Point to Undefined !STACK 0 net.refractions.udig.project.render.RenderException: Problem beim Rendern:ShapeType changed illegally from Point to Undefined         at net.refractions.udig.render.internal.feature.basic.BasicFeatureRenderer.render(BasicFeatureRenderer.java:293)         at net.refractions.udig.render.internal.feature.basic.BasicFeatureRenderer.render(BasicFeatureRenderer.java:205)         at net.refractions.udig.project.internal.render.impl.TilingRenderer.render(TilingRenderer.java:79)         at net.refractions.udig.project.internal.render.impl.RenderExecutorImpl$RenderJob.startRendering(RenderExecutorImpl.java:286)         at net.refractions.udig.project.internal.render.impl.RenderExecutorImpl$RenderJob.run(RenderExecutorImpl.java:351)         at org.eclipse.core.internal.jobs.Worker.run(Worker.java:58) Caused by: java.lang.IllegalStateException: ShapeType changed illegally from Point to Undefined         at org.geotools.data.shapefile.shp.ShapefileReader.nextRecord(ShapefileReader.java:453)         at org.geotools.data.shapefile.shp.ShapefileReader.recordAt(ShapefileReader.java:566)         at org.geotools.renderer.shape.IndexInfo$Reader.next(IndexInfo.java:294)         at org.geotools.renderer.shape.ShapefileRenderer.processShapefile(ShapefileRenderer.java:489)         at org.geotools.renderer.shape.ShapefileRenderer.processStylersNoCaching(ShapefileRenderer.java:291)         at org.geotools.renderer.shape.ShapefileRenderer.paint(ShapefileRenderer.java:1286)         at org.geotools.renderer.shape.ShapefileRenderer.paint(ShapefileRenderer.java:205)         at net.refractions.udig.render.internal.feature.basic.BasicFeatureRenderer.render(BasicFeatureRenderer.java:278)         ... 5 more Any ideas?
