[Qgis-user] Dissolve function with various modules

[skampus]

I'm trying to dissove a shape file of polygons as results of voronoi diagram
made by sextante mmqgisx.
three modules are in sextante and none works

1) saga
two options used (with inner boundaries and without): the boundaries still
exist

2) ftools: the resulting polygon is empty
Dissolve instance has no attribute 'myParam'
Traceback (most recent call last):
  File
"C:/Users/skampus/.qgis//python/plugins\sextante\core\GeoAlgorithm.py", line
116, in execute
    self.processAlgorithm(progress)
  File "C:/Users/skampus/.qgis//python/plugins\sextante\ftools\Dissolve.py",
line 141, in processAlgorithm
    tempItem = atMap[ self.myParam ]
AttributeError: Dissolve instance has no attribute 'myParam'

3) grass: it seems that it does the work but an error occurs at the end
the configuration region is set as default, "use min covering region"
activated

4) ftoos from vector menu: error in creating output

5) arcgis: it works :-(

QGIS 1.8
Sextante 353
