How to ignore Null bean properties

[Chris Hane <ch...@gmail.com>]

I'm converting an app to use Trinidad.  We use nested properties like:

<h:inputText value="#{bo.sale.org.name}" id="nme" readonly="true"/>

When I convert to Trinidad I am using the following:

<tr:inputText label="Name" value="#{bo.sale.org.name}" id="nme"/>

If the org property on the sale is NULL, Trinidad throws the following
exception.  The stock component with myfaces does not throw the
exception - it treats the value as a blank.  Is there any way to have
Trinidad do the same thing without resorting to a bunch of null checks
on the page?

I'm also using facelets in both cases...

Thanks in advance,
Chris....
