include FlexBuilder;

RIA != RAD; // Always True

Just my 4 cents.

1. If the Application you’re building is named Foo.mxml, and “Generate HTML Wrapper” is checked in the Project properties panel, Flex Builder creates its own Foo.html and Foo-debug.html files in the output directory on build. To change the HTML files it outputs, modify the index.template.html source in the html-template/ directory Flex Builder creates. HTML files with other names shouldn’t be clobbered.
2. Do the errors appear in the Problems view? Choose Window→Problems and hit the filters button (leftmost icon on the top right of this view) and make sure the filter shows errors “On any element.”
3. Usually I move the files around but leave out the directories FB creates, like .actionScriptProperties and .settings/. Then, whenever I’m setting up the project, I configure the project settings in flex builder all over again. Just a little bit of trouble (no more than a dozen clicks) but keeps the project much more portable.

HTH! //Roger

1. Flex appears to delete html files from the bin directory. When trying to run the application or debug it says that the html file can’t be found (especially the debug versions. I have confirmed that I have the most recent debug version of the Flash player).

2. When trying to run the application, it says that there are errors in the application and asks me if I want to continue. Why are some of the errors marked with the red error icon and others aren’t. I’m now stuck with having to look through thousands of lines of code to find the “mystery” errors since Flex has supposedly found them but told me nothing about them. Any ideas on how to troubleshoot these better?

3. I have yet to be able to export a project to another system without it being full of errors at the destination resulting from things that either didn’t copy correctly or were not packaged in with the app during the export.

• Configure Flex to launch apps in a different browser, or a browser that spawns multiple processes for multiple sessions.
  Click Window → Preferences, General → Web Browser, check “Use external Web browser” and pick a browser that isn’t your default or runs in multiple processes (typically IE for firefox users).
• Configure firefox to
  run in two processes concurrently
• Debug your app in the Flash Player standalone version. Right-click your project and select Properties, go to Flex Compiler → HTML wrapper, uncheck “Generate HTML wrapper file.”

To resume execution you can hit “Resume” (play button) in the deubug view… to stop debugging and detach the debugger you can hit “Disconnect” (the two red dots). Or to close the process entirely you can hit “Terminate” (the stop button). Resume will keep catching exceptions and breakpoints. Disconnect will let your app keep running but no more debugging. Terminate will stop debugging and close the app.

thanx for the comment.
