Not able to debug with Flex Builder 3

Question

Hello

I use Flex for a short time, use a bit pushed to my client for a solution-oriented monitoring.

Background:

Platform:

• Windows XP

• Eclipse 3.4 Ganymede

• Flex Builder 3.0.2 Licenced
• JDK 1.6_20
• Firefox 3.6
• Flash Player 9 (Debug version)
• Server: OSGI (Eclipse equinox) an instance of jetty service allows HTTP requests

Requirements: Make debugger in ActionScript by putting "BreakPoint" to assess the contents of variables.

Problem: The code does not stop at breakpoint, worse, if a breakpoint is enabled, the module flex does not start.

Actions: Reinstall all the dev environment (Eclipse, Flex Builder, Flash Player): KO Removing repo maven modules and complete rebuilds: KO Restarting Windows: °) KO

Logs: this is what the log contains just after launching the platform (modules) in debug mode.

Answer 1

You could try updating your debug player to see if that has an affect.

Where does that log come from? Is it an eclipse log? Or something you see on the server? Is Eclipse crashing?

When you use the 'term' Module are you referring to Flex Modules ( http://livedocs.adobe.com/flex/3/langref/mx/modules/Module.html ) or are you using the term more generically?

If using Modules; have you tried to test the module separate from the rest of the application? Create an application that is the Module instead of using the ModuleLoader. Does that have an affect?

Which version of the Flex SDK are you using? Can you upgrade to 3.5 or 4.0 ?

Answer 2

a work around is to do following : 1. export preferences and exit Eclipse 2. delete .metadata folder 3. launch Eclipse and recreate the workspace 4. import preferences. It works all the time.
