Flex Builder not building changes

I'm having a very strange bug in Flex Builder where none of the changes I make are appearing when I debug/run my program. It only happens with a particular AS3 project, on others, it works fine.

For example, I have a line,var x:int = this.prevX + this.x;, whose value is 400 if I don't make any changes. I change the line to var x:int = 0; and set a breakpoint on the line. When I debug the program, it breakpoints just where it should, but the value is set to 400, even when the line is x = 0! What gives!

I've tried cleaning the project and deleting the project and re-importing it. No matter what I do, it won't show any changes I make, even if I开发者_如何学Python just toggle a boolean. It still won't let me compile with errors, but once its done compiling, it completely ignore whatever changes I made. It's like it has the bytecode for the swf cached somewhere and its just ignoring doing the actual build step.

Any ideas?

Check if you have a copy of the swf in the html-template folder. The newly compiled swf will be overwritten by that old one after each build. Happened to me once.

Right click the project in the Flex Navigator and then click Refresh. Refreshing the project worked for me.

Changing from IE to Chrome worked for me.

I was having trouble with this as well, and deleting the html-template folder didn't fix the problem for me. I then renamed the project and it worked after that.

I get this too. This is the first time I've found this referenced on the net. It's a BIG problem. I get it periodically. For me, it's not the html-template folder. I've got a couple of ways around the problem at the moment

1. Delete the bin-debug swf
2. Overwrite it with a release build.
3. Delete the release swf
4. Export the release build elsewhere.
5. Build a debug version again.

This works - sometimes immediately sometimes after a few repetitions.

One other technique I tried today was to change the compiler options to -dump-config=somefile. This worked immediately, however, I'll need to wait next time to try again. It might be a situation of changing the -dump-config filename output when this happens.

Just tried another possible fix (which seems to be working really well) - Change the browser that Flex builder is using to a different one. This immediately fixed the problem. I'll post back here later if I find that this is a reliable fix. - Casp
