I am using JFace in a stand alone application (does not run inside
Eclipse). I would like to have various options on the CoolBar appear or
hide depending on what is selected in the UI. The CoolBar managers
are not behaving the way I expect them to. It is not clear to me if
this is a bug with the CoolBar managers or if I am just using them
incorrectly.
The goal of the program below is to have the "Blue" items appear on the
CoolBar when the "Blue" button is pressed but go away and be replaced by
the "Red" CoolBar items when the red button is pressed. The actual
behavior is unpredictable, the items from the removed contributer are
there and can be pressed but are not always redrawn, sometimes the items
from the second contributer are displaced and sometimes not, other times
one will be painted over the other.
Please help. Is this a bug or am I going about this the wrong way?
Thank You,
Victor

as to why no one as answered my question.
a) Dude, your babblin'
b) Stupidest question every asked
c) You asked it in the wrong forum (if so where might be more appropriate?).
d) You post that much code and expect anyone to ready it . . . ya right.
Thanks,
Victor
