Flex Builder debugger breakpoint folows wrong lines

Question

this morning i start seing strange things happening with
flexbuilder, first it seeme that it was entering code that was
physically impossible; things like entering "if" clause and then
immediately entering " else " clause, finally i realized debugger
was showing lines when in reality it was executing lines that were
about 2-3 lines above what it was showing with breakpoint , I am
blaming this to flash player 10 debug version, maybe because its
still new there is bug ?
I hate to uninstall it and reinstall version 9, maybe there
is workaround to fix it.?

Answer 1

yeah I implied that, I did clean, I did manual clean I did
every possible option, then I uninstalled f player 10 debug and
reinstalled f player 9 debug, and while doing that discovered
another little bug in FB3 that could contribute to this issue ,
case is following :
I imported a flex project from my old machine where output
folder was /a/b/c
in my new PC output folder is /dev/a/b/c
so I went in project properties and adjusted output folder to
point to correct directory /dev/a/b/c but what flexbuilder is doing
is, it does not update all property files that have this path so
after you build the project, half of the assets go to new directory
/dev/a/b/c and half goes to old directory, /a/b/c, whats even
stranger is that if you close flex builder and reopen it, project
output folder gets reset back to point to old /a/b/c folder,
anyways I finally fixed it by manually modifying
.actionScriptproperties and .project files restarted FB cleaned
output folder,and then rebuild it, but now I am not sure did these
steps fix the issue or the flashplayer downgrade, or maybe both?
because I had to do these steps yesterday as well, and then
it was building correctly whole afternoon into new output folder,
but today it started it again, finaly I obliterated the existence
of /a/b/c path completely.
