[Gvsig_english] Geoprocessing Functions::Proximity::Buffer::Problem with dissolved buffer features

[Wolfgang Qual]

Hi list,
another test that produced the error message: Result layer empty...:
I created a buffer feature around some buildings with 30m distance. When 
activating the dissolve option within the buffer-dialogue, the buffer is not 
created and the error message appears.
If I deactivate the dissolve-option, the buffer is created. Therefore, I 
thought it should be possible to use the "Dissolve"-Geoprocessing tool to 
dissolve the boundaries in a second step, but gvSIG only gives me the already 
memorised (haha) error message (the buffer elements are overlapping very 
often- could this be a problem?).

Greetings,
Wolfgang
