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;
}
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?
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.
