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.

Hi Paco,
First of all thanks for your help.
I do not know if you see the class java that I send, but I have a problem.
I have two class DisegnaPoligonoExtension and DisegnaPoligonoPlugIn
DisegnaPoligonoPlugIn extends DrawPolygonTool and implements PlugIn, in the method install of the class DisegnaPoligonoExtension I must initialize DisegnaPoligonoPlugIn
private DisegnaPoligonoPlugIn disegnapoligonoPlugIn;
public void install( PlugInContext context ) throws Exception {
if(disegnapoligonoPlugIn == null)
{
disegnapoligonoPlugIn = new DisegnaPoligonoPlugIn(null);
.....
}
I initialize to null is correct? If no which value I can use
When I execute the extension I have the following problem
