RE: form properties and html:options with collection
Make sure you aren't redirecting the request, but rather forwarding. If you redirect (which I suspect your are doing) and the form is in the request scope, then you will lose all data set in the form. robert -Original Message- From: Sonam Belbase [mailto:[EMAIL PROTECTED] Sent: Monday, October 13, 2003 12:49 PM To: Struts Users Mailing List Subject: form properties and html:options with collection Hi, What is the best way of setting a Java Collection which holds Java Objects as a property of the form, and retrieving the Object and it's properties on a JSP?

Re: form properties and html:options with collection
Robert, In my action, on success I forward the request to a tiles definition called content.addNewName, which in return calls another definition. Could the data be lost because of this? action path=/journalSetType type=com.msdw.libra.ae.actions.selectNewName name=newNameForm scope=request forward name=success path=content.addNewName/ /action -SB Robert Taylor wrote: Make sure you aren't redirecting the request, but rather forwarding.

RE: form properties and html:options with collection
If you continue to forward, it shouldn't. But if you redirect anywhere in the chain, then that data is gone. Double check your attribute name spelling in your code and config file.

Re: form properties and html:options with collection
It's working now. I added a bean:define to define the bean which represents my collection of objects. I believe this is required in order to find the bean specified by the value of the collection attribute in the html:options collection tag. Thanks for your help Robert.

Good. I'm glad you got it working. I tend to use the html:optionsCollection .../ and populate my collection with LabelValue beans. It keeps things uncomplicated and simple.

RE: form properties and html:options with collection
IIRC, html:optionsCollection plays even nicer with LabelValue because of the defaults for the label and value attributes. In other words, I think Robert's example is equivalent to: html:select property=myProperty html:optionsCollection name=myOptions/ /html:select Quoting Robert Taylor [EMAIL PROTECTED]: Good.
