I think I did this once
IN the wod binding...
link: WOHyperlink {
action = yourAction;
?parameter = yourParameter;
}
Then, in your class...
public WOComponent yourAction() {
// add checks for nulls etc...
Object param = context().request().formValueForKey("parameter");
etc...
}
Or something like that...debug the form values, see what comes back
It's kids bedtime, so cannot check right now...perhaps one of the
illuminati can comment?

Hi All,
is it possible to pass parameters to action methods or to get the
attributes from the element that called the action method?
my problem:
I want to build a menu with hyperlinks. Idea: a WORepitition with a
Vector for the menu entries with names and pages that shall be called.
Works fine. Problem: when a reload is performed, clicking a menu entry
causes the corresponding page to be instantiated again, because
apparently the hyperlink using the pageName attribute calls a
pageWithName() that always create a new page.
A solution could be working with an action method that stores all
already instantiated pages in the session. For I am using a
WORepitition containing one WOHyperlink I only can declare one such
action method. But this action method must return different pages
depending on the clicked hyperlink, so I have to pass a parameter.
Does anybody have an idea how to do this?
TIA
