Subject Re: Problem creating Facelet component using Trinidad
Date Tue, 23 Jan 2007 22:24:50 GMT
Thanks for the tip Chris,

AddressLookupBacking is the backing bean for an entire page,
tabOptions is just a List (property) within AddressLookupBacking.

I got it working by using c:forEach instead.  It had to with Trinidad
expecting a commandNavigationItem as the child of navigationPane.  With
ui:repeat, you get a ui:repeat component in the tree with children.
c:foreach happens at build time so there is no "foreach" component built
into the tree, just the child components (which trinidad knows how to
handle).  I guess this is one of the cases where c:foreach is preferable to
ui:repeat.  I know this could probably be done more elegantly someway using
ui:repeat but I can't see it.  Again, this is just one noobs first foray
into Facelets components.

Thanks again!!
