I guess its time to learn struts-el, JSTL (remove inline scripting) and dynaforms!!! Man!! This just never seems to end. The next up challenege to get the damn checkbox retain their states!!. Using array for checkbox to retain an ID Something like this <input type="checkbox" value="6"name="stateId[0]" /> <input type="checkbox" value="7"name="stateId[1]" /> <input type="checkbox" value="8"name="stateId[2]" />
So which ever checkbox s checked its value is set. Any clues? -----Original Message----- From: Mark Lowe [mailto:[EMAIL PROTECTED] Sent: Tuesday, October 28, 2003 1:09 AM To: Struts Users Mailing List Subject: Re: Index properties (once again) That's okay Rajat as I said I know what its like to up against the wire.. I've found ArrayList works better in dynaActionForms especially if you're dynamically generating forms. I think this because its a big fat pain in the arse to create new dynabeans (have a play with bean utils for a day and you find this out). When setting the size dynamically you need to scope the form to session. <action path="/myaction" scope="session" .. I use arraylist as the form property type, i don't think that arrays work but i could be wrong <form-property name="myprop" type="java.util.ArrayList" /> [notice you dont set the size] then in your action when your loading the form ArrayList list = ... theForm.set("myprop",list); and also (I guess this shouldn't be required but it is)... request.setAttribute("myprop",list); then <logic:iterate id="prop" name="myForm" property="myprop"> <html:text name="prop" property="foo" indexed="true" /> </logic:iterate> I guess you could apply the same principles using non dynamic action form. I imagine that using an array rather than arrayList should work too.
