[#2762] - $X function delimiter is replace with comma on any action in design view

I have some functions like this:

AND $X{IN| vs.mfg_plant_code| plantCode}

Anytime you perform any action in the designer view, such as re-sizing a column the pipe delimiter is replaced by a comma. This breaks some sql such as:

AND $X{IN| nvl(vs.mfg_plant_code,0)| plantCode}

Since the expression contains a comma, the pipe delimited is required.

Please fix this so the pipe is left alone and not replaced.
