Hi Adam,
Thanks a lot for the reply.
The reason I tried that is to actually do a check for null value.
In my code I have something like:
value="#{a.b.c}"
As I understood from the EL documentation - if a.b is null, a.b.c should
automatically resolve to null.
However in my code, if a.b is null it fails with the error:
javax.servlet.ServletException:
...
Target Unreachable, 'b' returned null
javax.faces.webapp.FacesServlet.service(FacesServlet.java:202)
What would be the best way to get around it?
Thanks again,
Regards,
Magdolna

A value expression like #{true ? ... : ...} is not writable -
if you call ValueBinding.isReadOnly(), it returns true.
As a result, Trinidad automatically turns the
selectOneChoice to readOnly mode.
For a writable EL expression, you have to just point
at a bean property.

Hi all,
I have a drop down list and I am trying to set the value selectively.
Whenever I use EL in the code, the drop down list disappears and instead,
it
has the appearance of an output text.
Any hints?
Thank you,
Magdolna
Here is a simple example:
<tr:selectOneChoice id="ex" label="Example" value="#{true ? 'L1' : 'L2'}">
<tr:selectItem label="L1" value="L1"/>
<tr:selectItem label="L2" value="L2"/>
<tr:selectItem label="L3" value="L3"/>
</tr:selectOneChoice>
