Re: [Flow] Serious problem with cocoon.getComponent(id)

[Christopher Oliver]

I can't reproduce this. Are you sure you don't have an old version of rhino
in your classpath? I fixed a problem with setting up dynamic scopes 
recently.

You need to describe how to recreate the problem in more 
detail 
   

ok, here some more details:

As you can see I implemented cocoon.getComponent(id). If I call
this method from the flow and do a lot of refreshes at once
(pushing the F5 key at IE) this error occurs.
If I include a debug statement writing the ComponentManager to 
System.out I sometimes get null and not the manager.

IIRC last week a problem with the petstore examples and the
database connections was reported altough the "old" implementation
exposed the ComponentManager itself.
If you need more information please let me know!

for me to help you. The component manager will only 
become null when the FOM_Cocoon object is invalidated. Your 
scripts should not be executing in this state. If they are 
that that indicates a bug and we need to find it.

Regards,

Chris

I think we have I serious problem with the lookup of 
components within flow scripts. Under load the component 
manager can become null!!!

Could somebody with more knowledge about this part of Cocoon 
have a look at it?

TIA!

Cheers,
Reinhard
