Show loading icon when map isn't loaded until later?

All the examples I've seen for showing a loading have a listener set to the map.

         dojo.connect(map,"onUpdateStart",showLoading);
        dojo.connect(map,"onUpdateEnd",hideLoading);

My project doesn't load the map at the beginning. Instead, the users runs a query or find which generates a list. Only after the list is displayed do they have the option to see the results of their query/find on a map.

It takes a moment for the page to open. If the user selects a county or enters an address before it's fully initialized, they get errors. I feel like too much is still loading at the beginning. I tried commenting out the dojo.addOnLoad(init) that most examples have because I know I don't need the map until the user makes some sort of selection. Still it seems to be accessing the baselayers right when I start.

I can add the loading image at start up by putting it in my top borderContainer, but I need to have something else besides the map's onUpdateEnd event to trigger the hideLoading function.

I have a loading message in one of my apps that appears when I start the search and then leaves when the results are found. I did this simply with:

grid.showMessage("Loading...");

I placed it above the line that returns the results.

This may be useful to you, not sure.
