When it fails it doesn't throw an error, but it just retrieves a string of length 1, instead of retrieving the actual text of the chain. I see this on 1.5.6.1 and 1.5.7.svn, in both Linux and Windows.

The text frame name "debug" at the very top will contain the word "Error" if the getAllText() call in the script fails.  What I see is that it works fine the first time, then it fails on every subsequent try, until I alter something on the document.  For example, if I grab and move the "debug" text frame a bit then getAllText() will succeed once, and then fail repeatedly again.  Saving and reopening the document also causes the script to work again the first time.

Yes, I verified this works fine for me.  Thanks.

Digging into my code more I see that I was calling selectText() to select the first character of the paragraph I wanted to apply a custom paragraph style to, but then I was not deselecting the text.  A subsequent call to getAllText() would then return only the single character of that selected text.  To address this I've adopted a standard in my code of always calling selectText (0, 0, <text_frame>) right after making any call that relies on certain text being selected.

So, this problem is solved.
