This is an issue that I have been running into for months and have been unable to solve it. We have continued to develop our JavaHelp; however, we are at a point where this needs to be fixed and I am out of ideas.
What this is: A Java Application
-src --HelpsetProject.java //Main method to launch JavaHelp --help-hs.xml --help-idx.xml --help-map.xml --help-toc.xml --Images/ //images folder --Topics/ //Topics folder for html files
The application builds and compiles fine. It launches and runs fine, displaying the help as intended. However, fairly often when launched, the left side (item list/tree) will have a blank line or will be completely blank:
I originally thought that this issue was caused by missing map-toc tags, mistyped/mismatched xml tags/elements and general typos, as I am not the one actually creating these. However, I went over the files, validated and checked XML, double checked that all items on the list link to a file and clicked on every item in the list to see that it displays. The issue still persists, unless I missed something.
Here is the source code on GitHub.
Here you can download the executable and run it several times to see the error for yourself (It really is a chance for it to work/not work).
Any help is appreciated. Thank You!
