John,
I don't think there is anything that comes "out of the box" to do this,
however, you could create an element that cycles through the
context().request().formValues() NSDictionary and adds hidden fields to
your form.
Hope that helps
Regards
Peter

Hi John,
It sounds like you want to call a DA, then return the same page you
were on when calling the DA, and have the page contain the same values
it had before you called the DA. Correct?
No, I want it to accept the WOPopUpButton selections made by the person
viewing the web page. I don't need it to remember anything about the
state it had before. The same page yes, but not the same values it had
before.
If so, you can just pass all of the values you need to the da as
request parameters, outlined previously, and then make sure your
component can set them with either standard getters and setters or
using KVC.
I want the values to be set within a WOForm within my page. The values
are passed fine to the DA. I could take them out of the request myself
and work out how to set the WOPopUpButton selected values in the form.
But what I'm after is a way for the WOForm to take the values from the
request, the DA request without me having to do it. After all, the
values are in the URL, so why should I parse them to take them out and
set the WOPopUpButton states when I'm guessing WO can do it for me?
Sorry I haven't read those DA articles etc. but I will do.
Thanks,
John
Any other things required to render should be
able to be derived from what you're setting up in the component during
the DA.

I have a page containing a WOForm with
some dynamically created WOPopUpButtons. The WOForm is set to submit a
Direct Action request (using get as opposed to post).
The request received by the DA method contains information from a
couple of hidden fields in the form which allows me to construct and
configure the right page which is actually just a new instance of the
same page.
Is there a really simple way to get the WOPopUpButton values from the
request DA URL into the WOForm as if the WOForm had been submitted with
those values as a component action?
public String getSomeSelectedValue()
{
if ( someSelectedValue == null )
someSelectedValue = context().request().stringFormValueForKey(
"someSelectedValue" );
return someSelectedValue;
}
Yes, that's fine, I can get a named value no problem. But here I am
referring to an array of dynamically generated named values that make
up a WOForm content. My feeling is that I shouldn't need to pick out
the values, the WOForm should be able to take them from the request,
even if the request comes via a DA.
I tried calling
takeValuesFromRequest(request(), context()) from my DA method but that
produced a NPE. Perhaps this method can't work from a DA
request/context?
What's the stack trace?
I expect the above call makes no sense anyway, it was a long shot.
However, if someone says this should work, I'll give a stack trace.
Obviously I can parse the DA request,
dig out the WOPopUpButton selections and pass them to the page myself
and set the popup selections, but it strikes me that there ought to be
an easy way.
There's lots of ways to do things.
I'm just looking for the lazy man's way that will save me picking out
values now and in the future when I need to do similar again.
I will look at David LeBer's articles and podcasts as advised by Ramsey
and see if that helps.
Thanks,
John
