Flex debugging Bug

After the Flex web project is compiled, a Bug occurs in the debugging phase and I spent half a day on it. Finally solved the problem.

Details:

Code Private function onDiveceChange (event: Event): void
{
// Request. removeParameter (tracker. rcuInfo. id, tracker. currentIndex, "eeee", true );
// Request. removeParameter (tracker. rcuInfo. id, tracker. currentIndex, tracker. currentParameter );
Var network: String = event. currentTarget. selectedItem. network;

// If (tracker. linkble)
//{
// RemoveLink ();
//}
// Tracker. currentIndex = (event. currentTarget. selectedIndex) + 2;
// If (tracker. linkble)
//{
// AddLink ();
//}
//
Var a: Array = MonitorModel. getInstance (). field. getNetworkParameter (network );

Parameters. dataProvider =;

// Request. addParameter (tracker. rcuInfo. id, tracker. currentIndex, "eeee ");
Tracker. currentPar = this. parameters. selectedLabel;
}

The above code has been commented out. I just wrote it and compiled it once. Then I commented out the code.
However, when debugging, the bug occurs, and the single-step execution actually runs to the comment line.
I adjusted the bug for half a day and started the solution.
1. the Debug version of Adobe Flash Player has changed. After debugging several versions, the results are still the same.
2. For the svn reason, the code is exported and does not contain the svn directory. The result is the same and the problem remains unsolved.
3. the problem still persists when you reinstall Adobe Flash Builder.
Finally, it is easy to solve the problem. Because all my code is managed using svn, I carefully checked the Directory, which contains the html-template directory under the project directory,
The compiled ***. swf file in the directory. I used svn to check its version. The result was the previous version. I deleted it directly, and debugging the result would work.
