BUG:Nested loopindexes with the same loopindex variables

Bugs will be moved here once resolved.

Problem Description
If you nest loops and use the same loopindex, even if it is in a seperate function, it does not work correctly. In the example below, replacing the second "a" with a "c" causes it to loop four times rather than eight. This can be problematical if writing effective code functions in C2 - discovered this when I had nested loops with "xi", but the two loops with index "xi" were in completely different files.

Attach a Capx


Description of Capx
Three nested loops with duplicate loopindexes (loopindices ?)

Steps to Reproduce Bug
  • Step 1 : Run the above code

Observed Result


(from Browser log window)

Expected Result

Should be 8 outputs not 4. Or should warn about reusage. I'm hazarding a guess that loopindex is stored in a java hash in the runtime ? Maybe the loopindex value could be set to nil when the loop exits and if there is a loopindex already present when a loop is started causes a RTX ?

Thanks, good catch. Should be fixed in the next build. Note for me it did loop the correct number of times; it is just that the Chrome dev tools log would collapse identical logs in to one line with a number next to it. The issue was loopindex("a") was returning the least nested loop's index (event 2) rather than the most nested (event 4). From the next build, when identical loop names are used it returns the most nested first, which fixes it.
