I have a gmap in a rich:panel which starts out with some default lat lng. I also have a button which invokes java script back to server for lat lng from database. when button is clicked map is updated. Normal stuff.
The customer doesn't want the default map showing up at the beginning, they want only blank panel. They want the map to show up only after the button is clicked.
I can not find example of this. Always map shows up at beginning in all examples. I thought to try rerender approach but see other post which says this won't work for gmap.
Is there a way to start with a blank gmap that then is displayed after button is clicked.
