I generate the index for a book and place it in pages with a master of two columns per page. It loads fine, but the page number references have too much space between them, so my index is larger than I want.
I change the page number separation to be comma followed by en space. I repeat the process with the new page separation, and about a column and a half in, I get an error indication and the index jumps to the next single column page.
If I repeat the process going into single column pages, it does work, but if I then apply the two column master page, the same problem. The behavior is as if the page number part of the index is non breaking.
I've attached two screenshots. The first is the original place where it stopped flowing into the column of a two column page. The second is where I just deleted a couple of digits from the leading number of the entry that didn't flow properly. A dozen or so lines then popped in.
Second image follows:
Also, if you look at the second image, it is splitting page numbers at the end of the column,
I had this same problem back in 2006. At that time it was suggested that the thin space, en space, etc wasn't recognized as a space so indesign looked at it as one long word. Seems like it should have been fixed since then.

En-spaces are non-breaking and I suspect that's where the problem lies. I fyou look closely you'll also see that the lists break between the number and the following comma in several places.
Do you have any keep options applied to the paragraph style for the listings? My guess is you may have it set to keep the last 2 or 3 lines together, but noting for first lines. You might want to change that to keep all lines together if you don't want a listing to break across columns.
Thanks, Peter. I will go back to just a normal space. In the index generate panel, they display all the white space characters as options for word & number separators. It would help occasional users like me if the documentation talked about separator characters and which ones were non breaking. Yes, I did notice the breaks between commas and in the middle of page numbers. ID does strange things when doing its index psuedo hyphenation. A nice feature would be an option on the index generation page that said "allow breaks on whitespace characters".
