Make sure that you use the <html:form> taglib. Currently you are not
using it. It will get the bean for your page...
<html:form action="handleprojectaddrequest.do">
Select request type
<html:select property="codtyp">
<html:options name="projectaddrequestform" collection="listTyp"
property="id" labelProperty="name"/>
</html:select>
</html:form>

Subject: [Newbie] prob with <html:options> or <html:select> tag
Hi,
I have a weird problem here (as always :).
I have the following code in my *.jsp file:
<form action="handleprojectaddrequest.do" method="post">
Select request type
<html:select property="codtyp">
<html:options name="projectaddrequestform" collection="listTyp"
property="id" labelProperty="name"/>
</html:select>
</form>
so,
codtyp is a property of
HandleProjectAddRequestAction
projectaddrequestform is a session bean (it's actually loaded
into the session, because I did the check before in the jsp page)
listTyp is a collection (ArrayList) of
beans (type is one of mine named ElementSimple)
id and name are two properties of the class
ElementSimple
My session bean is well loaded.
My ArrayList does contain values.
So why do I have an error when I try to execute the preceding code ?
Thanks for having read me so far :)
Friendly Regards,
Slimane
