Hi All,
I'm looking for some info about how to properly remove and re-add non-cached files. To set up the situation, I have access to weather shapefiles that are generated every five minutes, and wish to display these files on top of a cached 'world' overlay. Largely, this has been successful. I am doing this by adding several different layers of weather into one LayerOverlay, and adding this LayerOverlay to my map as a CustomOverlay. On the same page as the map, I have a timer that ticks every five minutes that is supposed to refresh the weather, but leave the underlying 'world' overlay. To do this, I am refrencing the weather overlay, removing it from the map, and readding it using the same method above, just with a the new shapefile. As I said before, this works wonderfully for quite sometime. However, after a while of letting this refresh cycle happen (sometimes hours), I start getting pink tiles all over the map, making it completley inoperable. What causes this? Is there a better way to go about doing this? Thanks for your help!
