DEAR PEOPLE FROM THE FUTURE: Here's what we've figured out so far???
I have created an ArcGISLocalFeatureLayer with a different spatial reference from the base layer, then I create a polyline that is added to the Graphics container of the layer.
As my data is in another spatial reference, I remove the layers from the map, change the spatial reference of the map and add the layers again.
then i try to perform ZoomTo using the geometry of the polyline and get this:
Any Idea???
if i try to make the zoom with mouse whell it works perfectly

all is based in the layer's lifecycle.....
I must performed the zoom operation when the layer is created, initializated and updated.. if i tried the zoom operation before al these three stages...the exception is thrown, because the full extend is not set
