[Biojava-l] viewsequence is unchangeable?

[mark.schreiber at group.novartis.com]

Very good question!

Maybe the idea was to make views on views. Seems a bit odd though. Does 
anyone know what the ideal solution here is?

The Change support in biojava does derive from the standard java system 
but offers some more flexibility about pre and post condition changes and 
vetos. On the whole it may be overkill but could be useful for large 
systems.

Hi everyone,

why is ViewSequence an implementation of the Unchangeable interface? 
Isn't a view (among others) meant for adding features to an otherwise 
unchangeable sequence?
I have a class derived from the view, but I don't get it to notify the 
GUI when changes occur, as I don't find the getChangeSupport() in 
ViewSequence...
[Well, simply adding standard java change support instead of this overly 
complicated biojava system would also do the trick... :-) ]

Thanks
Max
