Component#userData should allow multiple clients to co-exist
-------------------------------------------------------------
Key: PIVOT-67
URL: https://issues.apache.org/jira/browse/PIVOT-67
Project: Pivot
Issue Type: Improvement
Components: wtk
Affects Versions: 1.1
Reporter: Noel Grandin
Priority: Minor
It is very handy to be able to stash extra info on a component, but when
multiple libraries all want to do this, it quickly gets out of hand.
When multiple libraries all want to do this, they can conflict e.g. if I add
LibraryA and LibraryB to my pivot application, and both libraries want to
enhance standard Pivot behaviour by stashing stuff in the Component, they
will overwrite each others UserData.
A better solution would be to use a map of values with methods like
void putUserData(Class key, Object userdata)
Object getUserData(Class key)
