hi can anybody tell me how to set '--' if the column value return null

how will you use if condition in jsp page using jsf.

You could write a custom javax.faces.convert.Converter for that. For example, if you had Date fields that were nullable, you could define a custom DateConverter and even register it as the default converter for Dates.

Hi Jeff,

Thanks for the reply.

But the JSF document shows that converter used to convert values to particular datatypes.

but in my situation, i getting the result from the database and i want to show it to the user.

if any column does not contain value , then i need to show "--" instead of blank.

how will you do this???

Hi jeff,

I got my desired output. I tried like this it works fine.

<h:column>
<h utputText value="--" rendered="#{ListName.propertyValue==null}">
</h utputText>
<h utputText value="#{ListName.propertyValue}" rendered="#{ListName.propertyValue!=null}"></h utputText>
</h:column>

here ListName is the arraylist which hold the values and
propertyValue is the bean property.

cheers
