<p>Hi all, I want to submit two issues (bugs?) to developers.</p>
<p>First issue: multiple intersections<br>I want to find all intersections between two different layers of polylines.<br>To do this, I use the "intersection" algorythm of gvSIG. <br>The resulting point layer leaves out all multipart intersections (i.e. when a line of the first layer intersects a polyline of the second layer in more than one point).<br>
If I perform the same geoprocess with OpenJump, the resulting layer contains multiple intersections too (one multipart feature for each multiple intersection), so that I can explode multipoints in many single features (points) in a subsequent step.<br>
The workaround using gvSIG is to split previously all polylines in single segments, so to avoid multiple intesections.<br>Al gvsig versions (1.11, 1.12, 1.2) show the same behaviour.<br>I think that it is not a good behaviour.</p>
<p>Second issue: intersection between a polyline layer with a clone of itself.<br>No problem using gvSIG 1.11, while using gvSIG 1.12 (build 1411) it appears an error message. The corresponding lines in gvSIG.log are the following:<br>
