NetBeans: Code folds do not appear on one of my PHP files

Question

I'm using the NetBeans IDE. Normally, every PHP file in my project has code folds:

However, one PHP file in my project doesn't have code folds:

The file has no syntax errors. I've tried restarting NetBeans and reopening the project and the folds still do not appear. What could it be?

More info:

• I'm using NetBeans IDE 7.0.1.
• The file's extension is .php like all the PHP files in my project.
• On another file which has the same content exactly, code folds appear.

Answer 1

@ sudhir chauhan: If code folds wasn't already selected the other php files would not have folds alredy.

This is a known bug with Netbeans that is very annoying and happens occasionally to me as well when editing PHP. The only solution is to save the file, close the Netbeans IDE and re-open Netbeans.

Also sometimes you unfold code and click to refold and you cant.. to resolve this related issue just click on a line outside the fold (ie. the function above) then click on the "-" to refold the code.

Answer 2

This problem persists in Netbeans 7.2.1, not only with PHP, but also with java code, the way that works for me is to uncheck [Use code fold:] as described in o0omycomputero0o's answer, apply changes by clicking OK, then recheck [Use code folding:], and click OK, it sort of re-validates the code folds to the expected state, No IDE reload needed.
