[Geoprisma-dev] GetlegendGraphic called each time zooming in or out (r805)

[Djoan Bonfils]

  Hello,

When adding

<resource>
<name>RS_issues_by_location</name>
<widgets>
<widget>Toolbar</widget>
<widget>W_MyLegendPanel</widget>
</widgets>
</resource>

to get the legend Panel, using firebug, I observed  that a 
getlegendGraphic is performed on each layer each time I'm as zooming in 
or out even when these layers are not checked.
I was wondering how this was affecting global performances...


Regards

Djoan
