Re: How do I make a checkbox initially checked?
Hi, Yes, it works fine if I use prepare() and create my own object. However, my understanding from the docs was that struts would create my object for me, based on hitting a null pointer. But that does not seem to be the case. Also, if I use the value=true method, then my box is checked always, regardless of user input.

Hi again, I'm working on a form where a particular checkbox should be initially checked when the form first comes up. None of the options in s:checkbox seem to support this. I tried to have my backing object initialized with the particular Boolean set to true, but struts doesn't seem to actually create my object (counter to the docs), until submission time. If I have: s:checkbox name=user.sendEmail/ The docs say that if user doesn't exist (which is the case on initial display of the form), OGNL will get a null value, and struts will create a user object. This doesn't seem to be happening. Is there a way to do this using the UI tags?

Re: checkbox initially checked?
Hi , As Wendy has mentioned- Otherwise, the place to do this is in your Action, before you forward to the JSP. I am interested in populating Form before loading jsp page so that I can assign values to HTML comtrols. HOw to do that?

RE: checkbox initially checked?
Thanks it worked! Actually had List of Objects I was forwarding. And in my action class I just did the following as I was building the list Object.setSelected(true); Where the Object class had a boolean called selected. -Original Message- From: Dave Newton [mailto:[EMAIL PROTECTED] Sent: Thursday, August 04, 2005 12:11 PM To: Struts Users Mailing List Subject: Re: checkbox initially checked?

Html: checkbox initially checked?
New to struts so sorry for the simple questions. I have a html: checkbox struts tag and I want to have the checkbox checked initially similar to the checked attribute in a traditional INPUT statement. Can you do this? I've looked everywhere!

Re: Html: checkbox initially checked?
If memory serves me, the way to do this is in your ActionForm's reset method. This is where default values are specified when the form is initialized or reinitialized.

Re: checkbox initially checked?
I should have distinguished between session-scoped and request-scoped forms. It is true that implementing reset would be redundant in a request-scoped form.
