Using greater than logical expression in rendered attribute

I have an outputText field for which I write a condition in the rendered attribute. The condition is for comparing the length of the string with some numeric value.

<h:outputText id="emailaddress" 
    value ="#{subsAlertsHelper.personEmail.substring(0,20)}"
    rendered="#{subsAlertsHelper.personEmail.length() >20}" />

If I use == or != in rendered it is working fine. But for greaterthan and lessthan it is not giving the output. What could be the reason for that?

You have to use gt and lt operators.

Check out JavaServer Faces Expression Language Intro from Sun/Oracle. Precisely the Operators section.

rendered only accepts EL expression.

subsAlertsHelper.personEmail.length() is incorrect.

On the personEmail object, add a method getLength() witch returns the length

public int getLength(){ return this. length();}

Modify :

rendered="#{subsAlertsHelper.personEmail.length >20}"
