Our solution to this dilemma was to set the eventSubmit_ input element
dynamically using JavaScript (I know...I don't like using JS either :)
). This is in our global JS include file.
The relevant JS code looks like this...
/*
* Used for adding a hidden <input/> tag to the search form.
*
* form - The form to submit.
* event - The action event name. Maps to a method of the action class.
* value - Passed to the action event handler.
*/
function invokeActionEvent(form, event, value) {
// construct the navigation input tag element
var inputTag = document.createElement("input");
inputTag.type = "hidden";
// specify the 'doXxxxxx' action event
inputTag.name = "eventSubmit_do" + event;
inputTag.value = value;
// add the tag to the search form
document.forms[form].appendChild(inputTag);
// submit the form
document.forms[form].submit();
// remove the tag from the form, because we are done with it
document.forms[form].removeChild(inputTag);
}

This works _almost_ :)
I like this suggestion it works very well, but now i have the problem
that I
have two functions being called by two different links, so I have:
<input type="hidden" name="eventSubmit_doExpand" value="1">
<input type="hidden" name="eventSubmit_doAdd" value="1">
and now what happens is that depending on which link I hit, either the
Expand or the Add, the backend function called will always be the same.
So
in other words, if a vist my page, hit "add", it calls the add function
in
my backend. But then if I hit the "expand" link, it also calls the add
function in my backend. Any suggestions as to how to, for lack of a
better
word, "clear" the page so that this behavior is not observed?
thank you!
Luke
