The following error (sorry about the length - I tried to attach it but was getting errors) occurs in FB5 (upgraded from FB3). It appears to happen when a particular include script is called more than once. Other includes that are called more than once are working fine. Are there any other details that would help diagnose this issue?

Hi Allen
Please email support with the project files (main and included) and the log file for the main project (and the bug report file).

Hi,
I’ve been having the same problem with FinalBuilder4 projects. I have a main project that iterate through a list of build/config nodes in an xml file and calls a build project for every config nodes. The error happens when running the build project for the second config node. For test purpose, I changed the main project so it would statically call the build project twice and did not get the error but using a file iterator instead of the xml iterator did reproduced it. I temporarily solved the problem by merging both projects into one but by doing so, I have to give up the flexibility I had with the two seperate project.
Here is the first paragraph of the error message I get:

you talked about a fix (in FB5) which dramatically reduced the time taken to export the log file.
Has it been possible to incorporate this fix in this new build of FB4?

Hi Ken
That change as merged back into the 4.x branch on Jan 23rd, I’m not sure when the build was done but I suspect it’s more recent than that (will check at work tomorrow).
