[Gvsig_english] error while using geoprocessing tools

[Wolfgang Qual]

Hi list,
I tried to create a new feature using the union-tool of the geoprocessing wizard. However, gvSIG does not calculate the correct result - the wizard crashes and gives the following error messages in the information connsole:

null java.lang.NullPointerException: null     com.iver.cit.gvsig.fmap.core.v02.FConverter.java2d_to_jts(Unknown Source)     com.iver.cit.gvsig.fmap.core.FGeometry.toJTSGeometry(Unknown Source)     com.iver.cit.gvsig.geoprocess.impl.intersection.fmap.IntersectVisitor.visit(Unknown Source)     com.iver.cit.gvsig.fmap.operations.strategies.DefaultStrategy.process(Unknown Source)     com.iver.cit.gvsig.geoprocess.impl.union.fmap.UnionGeoprocess$UnionMonitorableTask.run(Unknown Source)     com.iver.utiles.swing.threads.MonitorableDecoratorMainFirst.run(Unknown Source)     com.iver.andami.PluginServices$1.construct(Unknown Source)     com.iver.utiles.swing.threads.SwingWorker$2.run(Unknown Source)     java.lang.Thread.run(Unknown Source) null java.lang.NullPointerException: null     com.iver.cit.gvsig.fmap.core.v02.FConverter.java2d_to_jts(Unknown Source)     com.iver.cit.gvsig.fmap.core.FGeometry.toJTSGeometry(Unknown Source)     com.iver.cit.gvsig.geoprocess.impl.intersection.fmap.IntersectVisitor.visit(Unknown Source)     com.iver.cit.gvsig.fmap.operations.strategies.DefaultStrategy.process(Unknown Source)     com.iver.cit.gvsig.geoprocess.impl.union.fmap.UnionGeoprocess$UnionMonitorableTask.run(Unknown Source)     com.iver.utiles.swing.threads.MonitorableDecoratorMainFirst.run(Unknown Source)     com.iver.andami.PluginServices$1.construct(Unknown Source)     com.iver.utiles.swing.threads.SwingWorker$2.run(Unknown Source)     java.lang.Thread.run(Unknown Source) null java.lang.NullPointerException: null     com.iver.cit.gvsig.fmap.core.v02.FConverter.java2d_to_jts(Unknown Source)     com.iver.cit.gvsig.fmap.core.FGeometry.toJTSGeometry(Unknown Source)     com.iver.cit.gvsig.geoprocess.impl.difference.fmap.DifferenceVisitor.visit(Unknown Source)     com.iver.cit.gvsig.fmap.operations.strategies.DefaultStrategy.process(Unknown Source)     com.iver.cit.gvsig.geoprocess.impl.union.fmap.UnionGeoprocess$UnionMonitorableTask.run(Unknown Source)     com.iver.utiles.swing.threads.MonitorableDecoratorMainFirst.run(Unknown So

Any comments are welcome.
