[mapguide-users] DigitizePoint from a new browser window

Mon Sep 14 03:00:24 EDT 2009

Try using firebug and set a breakpoint, you can then examine the 
variables, and see what they are.

For this example your code resides in the current page, so I don't 
understand why you call opener.mapFrame to activate the function.
Next up, when you call parent.parent.mapFrame, you do so from another 
window, and thus parent is either null or self.

For this reason, there exists a function called GetMapFrame() which you 
can call from many places.
By using this function everywhere you can simply put in your own 
function in the page, and everything works as expected.
The function would look like this I think:
function GetMapFrame()
{
    return opener.GetMapFrame();
}
