Description Gerry Kessler CLA 2006-07-05 17:46:10 EDT 
The value attribute is being incorrectly marked invalid with "EL expression does not evaluate to expected types for this attribute". 

<h:inputText value="#{bean.val}"/> when val is an object.   

<h:inputText value="#{bean.date}"/> is another example.
Comment 1 Gerry Kessler CLA 2006-07-05 18:02:10 EDT 
I neglected to mention that a converter has been applied in the above cases that could convert to a String.

Example from Core JSF samples: converter2

   <h:inputText id="card" value="#{payment.card}">
       <f:converter converterId="com.corejsf.CreditCard"/>
   </h:inputText>

where, 
public class CreditCard {
   private String number;

   public CreditCard(String number) { this.number = number; }
   public String toString() { return number; }
}

Triaged for WTP 2.0
Comment 3 Martin Zwosta CLA 2007-02-12 14:10:53 EST 
Encountered the same problem (with the standard date-converter).
My System: OS: Win XP prof., Apache 5.0.31, myfaces 1.09.

Need to defer this one to 3.0 unless it is critical for anyone.  Requires the ability to analyze nested components.

See https://bugs.eclipse.org/bugs/show_bug.cgi?id=202697 to track future improvements in this area.
