I got a lifetemplate like this: trans: I18N.translate($FOO$) Now inside a method call i try to invoke it: button.setLabel(trans<Press TAB here> Now if the method parameter tooltip is displayed, the template is not expanded. I have to close the method parameter tooltip by pressing ESC, after which the expansion is working. While this is not having a too big impact, since a workaround exists, it still hinders the flow of development as i got to remember to press ESC evertime...
