[Haggle-arch] AbstractDataManager question

[Oskar W. <os...@it...>]

I have a quite specific code question, but it seems this list may be  
the place to send it anyway.

When writing a small haggle test application, I never got my  
DOListener called (added using addListener(...) in the AppInterface  
provided to appInit(...)). After a bit of debugging I found that  
there was never anything inserted into the dofilter_listeners HashMap  
in AbstractDataManager. Adding a dofilter_listeners.put(listener,  
filter) in the synchronized block of addListener(...) in  
AbstractDataManager thus made it work.

My question is if I can commit this small change or if there is some  
alternative method of adding data object listeners so that I should  
leave AbstractDataManager alone?
