Scoping issue - calling an internal dojo function from external function

I have a function that is outside of the require portion of the dojo functions.

This function needs to call a function that resides within the dojo require block.

How do i call a function that is within the require code block from a function that resides outside the dojo require block?

Perhaps a little more application flow will demonstrate the need

• Main window application spawns a child window
• Main window sends a message to the child window that has a global function that will receive the message
• Child window receives the message
• The external function parses the message and determines that the map needs to be updated (The child window that is spawned is the mapping window and loads a lot of ESRI modules in the require section)
• the child window function needs to call a function that is within the require code block of dojo to do the actual ESRI related tasks

Talk about a hack... here is what i did to get the results i needed.

I created a hidden button on the form, bound the click event to fire off the function.

When the message was received and processed, I fired off the button click event - and viola!!

thanks everyone for the help.
