Topic: Re: Adobe's editor limited to number of bytes

There is no workaround.

The Acrobat editor is limited to 32 kByte. This number is also the
limit what an individual script can hold. Therefore, this seems to be
the limit for listboxes as well. However, there is a paragraph in the
Acrobat 5 Help file which says that one should limit the number of
items in a listbox (and a combo box) to 50. No reason why is given,
but I think that it has something to do with practicality because an
extremely long list is not so easy to handle.

An option might be using a pop up menu instead (with the popUpMenu()
method), where you still have the 32 kByte limitation, but you have
the possibility to group items and build up a hierarchy.

What you also can do is running several JavaScripts to populate your
list. You might run into the implementation limits, but you would see
that almost immediately either by an incomplete list, or by a system
crash.

Hope, this can help.
