thanks nino... that *is* the solution, works like a charm
my mistake for not paying attention to the last bits of the javadoc
ibehavior page :)
"boolean isTemporary()
Specifies whether or not this behavior is temporary. Temporary
behaviors are removed at the end of request. Such behaviors are useful
for modifying component rendering only when it renders next. Usecases
include javascript effects, initial clientside dom setup, etc. "
... couldn't be more clear...
cheers,
