Hi, created an Eclipse plugin that contributes to the UI by

• a new project wizard
• a new menu in the context menu of projects in the Package Explorer
• a new project nature + builder
• a new preference page for the plugin

The plugin works fine when installed in a normal Eclipse instance with Flex/Flashbuilder as plugin.

The problem now is, that the plugin never gets activated when i install it in a Flex/Flashbuilder Standalone instance. Neither of the features described above is available.

I even have no idea how to debug this, error-log (workspace/.metadata/.log) the following message appears, (but i dont think it is related to the problem)

!ENTRY org.eclipse.ui.workbench 2 0 2009-07-20 17:51:17.984
!MESSAGE A handler conflict occurred.  This may disable some commands.
!SUBENTRY 1 org.eclipse.ui.workbench 2 0 2009-07-20 17:51:17.984

In the "Configuration Details" my feature doesn't show up in the *** Features: section and my plugin doesn't show up in the *** Plugin-in Registry: section. But they appear under Configured features and Configured plug-ins.

Starting FlashBuilder with -clean didn't solve the problem. (the start command is now "C:\Programme\Adobe\Flash Builder Beta\Gumbo.exe" -clean)

My plugin depends on

org.eclipse.ui,
org.eclipse.core.runtime,
org.eclipse.core.resources,
com.adobe.flexbuilder.project
com.adobe.flexbuilder.project.ui
com.adobe.flexbuilder.ui

All of these should be available, as i see it. (and an error should be generated if they were not, i hope)
