Can't read anything in a second window object of the "on will open" handler

Hi All,

After switching to Xcode 3.0, I suddenly had problem with my application that worked with the old version of Xcode.

In my "will open" handler, I have these code snippets:

on will open theObject

try

set objectname to name of theObject as Unicode text

--no problem reading codes in window "main"

if objectname is"main"then

tell window"main"

--codes inside this tell block are read perfectly; no problem

end tell

end if

if objectname is "genPrefs" then

--display dialog "I am inside this if block (this line is not even read at all)

tell window "genPrefs"

--it follows that the codes inside this tell block aren't read either

end tell

end if

end try

end will open

Is there any particular reason why the codes in second "if-end if" block above can't be accessed? Note: The object "genPrefs" is a preference window that contains tab view and tab view items but the most immediate problem obviously is reading the first line (display dialog) in the block. I put that line simply for test.

Would appreciate any lead on the above problem.

Many thanks.
