[fusion-users] PanQuery and pink backgrounds

[Paul Spencer]

Hi Marc,

I haven't tried the panquery widget in a while.  The intention of the  
widget was to have a dual mode widget that if you click and drag, it  
pans and if you just click it does a query.  Looking at the code, it  
doesn't appear to have anything that would cause it to make two  
buttons.  Perhaps you have something unintentional in your  
ApplicationDefinition (widget declared twice perhaps?).

As mentioned in another reply, you can set  
OpenLayers.IMAGE_RELOAD_ATTEMPTS to some number greater than 1 - you  
need to do that after OpenLayers code has been loaded, the best place  
would probably be in the fusion initialized event handler

window.onload = function() {
   Fusion.registerForEvent(Fusion.Event.FUSION_INITIALIZED,  
fusionInitialized);
   Fusion.initialize();
}

function fusionInitialized() {
   OpenLayers.IMAGE_RELOAD_ATTEMPTS = 3;
}

Cheers

Paul
