LabelValueBeans

["CRANFORD, CHRIS" <ch...@setechusa.com>]

Is there anyway to have a property in my ActionForm class be defined as
follows:

private LabelValueBean[] myItems;

And be able to have struts automatically populate this collection when the
form is submitted?  If so, how do I go about storing those values in the
form so they're seen and populated properly upon submission?

Thanks!
Chris

You can rewrite or extend the class to suit yourself, of course.

No, look at the source for the class and you'll see why.

Well, a LabelValueBean has two string properties -- how would you 
automatically populate even a single instance, let alone an array?

Or are you suggesting that the form presents the user with a series 
of paired input fields, essentially "label1", "value1", "label2", 
"value2", etc?

If so, you could essentially do it by exposing an indexed property, 
"labelValueBeans" and then arranging to have your request parameters 
be named as such:

labelValueBeans[0].label
labelValueBeans[0].value
labelValueBeans[1].label
labelValueBeans[1].value

I would do this using c:forEach and the struts-el tags, roughly like this:

<c:forEach begin="0" end="5" varStatus="status">
Label: <html:text property="labelValueBeans[${status.count}].label" /><br />
Value: <html:text property="labelValueBeans[${status.count}].value" /><br />
</c:forEach>

If you aren't using the EL, there are other ways to do this, but 
frankly, I never learned how to do them and I think it's cleaner with 
the JSTL.
