[TxMt] How to edit Actionscript3 Templates?

When I edit a Template it stops working even when I edit just one tiny letter in an out-commented text.

I do the following: in the 'bundle editor' I expand the 'Project' Template and then I select the 'Project.as'. Here I placed the opening curly braces to be at the same line as the function (and not at the next line).

public function ${TM_NEW_FILE_BASENAME}() {

When I close the window and try to make a new project from template nothing happens. Even when I revert my changes it won't work anymore, I have to reinstall the whole bundle!

As said I also tried just to change a tiny letter in outcommented section of _create_as3_project.sh with the same result.

What is the proper way of editing a Template?
