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
