Display tag problem

[sudhir pavan]

I am listing values in jsp page using display tag using struts2.

In the jsp page i am using html checkbox element .
based on the list value i need to checkbox to be checked, otherwise unchecked.
if the value is true it should be checked if the value is false then unchecked
can you help me out?

Use EL like placing the code below in your checkbox tag

${true == yourObjectValue ? 'checked' : ''}

i tried like this but nothing selected

<input type="checkbox" value="${true == data.isread ? 'checked' : ''}" />

[Tim Moores]

Remove "true == ".

[sudhir pavan]

same result . nothing got selected

<input type="checkbox" value="${data.isread ? 'checked' : ''}" />

[Tim Moores]

What's the value of "data.isread" ? (Note that I'm not asking what you think it is, but what you verified it is in the JSP page.)

[sudhir pavan]

true / false

if its true then the checkbox should be selected
if its flase then the checkbox should not be selected

[Tim Moores]

Well, that much is obvious, because otherwise you couldn't use it in a "X ? Y : Z" statement.

But you said that nothing gets selected which I took to mean that for some element "checked" should be printed, but for some reason is not. That's not what you meant?

If it *is* what you meant, then verify that the value of "data.isread" for that particular element is what you think it is. (Note that "isread" would not trigger if the method in your bean is called "isRead".)

[Nikhil Padharia]

don't write EL inside value
Make it like

<input type="checkbox" ${data.isread ? 'checked' : ''} value="" />  

Also try making it data.isread == true or different combinations if it does not work properly

sorry nikhil it shows me error like "Unterminated <s:checkbox tag "

In Struts 2 , you can use the <s:checkbox> tag to create a HTML check box. The fieldValue=”true” is the actual value that will be submitted by the check box.
Just go through it this will really helpful for you. www.mkyong.com/struts2/struts-2-scheckbox-checkbox-example/

@sudhir pavan - it shouldn't , Post the entire <s:checkbox tag you are writing..
