Hi Giovanni,

try this code:

public void install( PlugInContext context ) throws Exception {
if(disegnapoligonoPlugIn == null)
{
FeatureDrawingUtil featureDrawingUtil = new
FeatureDrawingUtil(context.getWorkbenchContext());
disegnapoligonoPlugIn = new
DisegnaPoligonoPlugIn(featureDrawingUtil);
}
disegnapoligonoPlugIn.initialize(context);
}


I can't test the code now. Anyway, I hope it helps you.

Regards.
