[FR-devel] RUNNING state - Issue #2

[Laurent Julliard]

It sounds like the saga about the plugins state keeps going :-)

I have recently made the necessary modification to change the renderer
plugins state to RUNNING when they are actually running. By doing so I
noticed that the app is still running but the Databus inspector menu
item disappeared  from the Tools menu. I haven't yet investigated why
but I took a look at the freeride.log (see attached) and found a couple
of strange things in there which makes me think that the plugin
dependencies are not honored as expected.

A couple of examples:

- Line 40: AppFrameRenderFox goes to the RUNNING state although the
logger is still in STARTING state and only goes to RUNNING at line 70.
This seems to go against the depency in System_GuiRenderFox/plugin.xml

- Line 39: EditFrameRenderFox goes to RUNNING state before
AppFrameRenderFox. Again this goes against the dependencies in the
plugin.xml file

- Line 28: same applies for MenuPaneRenderFox

- Line 31: same applies for MenuBarRenderFox

I'm a bit puzzled by these inconsistencies and I wonder if this is a
problem in the way freeBASE manages dependencies or if the log messages
are not queued in the right order (I could not find how it could happen
given the fact that all log messages are queued at the databus level)

Any idea? I really think we need to clean up all these little nasty
details before other developers can really start working on FreeRIDE. I
encountered them while trying to develop the Debugger plugin and once we 
 get them out of our way, things will be much easier I guess.
