OK OK !!
My hands have been slapped and I immediately stopped. Though I
thought it might have worked.
Anyway, after refactoring my design and code I have another problem.
Probably has to do with the
RR loop thing again.
So after refactoring my code, I figured out how to use that
component, get the url from it, and embed
it in my javascript YUI Treeview. Everything seems to work great
except for one big confusing problem.
My link's action binding isn't being fired.
Here is the scenario:
Page
DocumentTree Component
Node Component
NXDowloadComponent
NXHyperlink
So it all renders correctly and even the href that is generated sure
looks correct. However, when I
click the hyperlink, it just won't fire its action method.
I doubled checked all the bindings. Is it because it is being
rendered dynamically via javascript
at the browser level?
Any thoughts would be very helpful
Thanks

James, stop it, It can't be done like that. Think about another

There are many options to solve this problem, but not knowing
anymore on how your app is organized, I would try to give extra
argument to the generated hyperlink (http://www.aa.aa/cgi-bin/
WebObjects/xxx.woa/wo/1.2.3?b1=true&b2=false&b3=true&data=key)
public WOComponent doMyStuffWithURL() {
String key = ... // get the key value from request url (sorry I
dont know the api from the top of my head)
...
return doMyStuff(key, b1, b2, b3);
}
public WOComponent doMyStuff(String key, boolean b1, boolean b2,
boolean b3 ) {
NXFileDownload fd = new NXFileDownload(context());
Item item = itemForKey(key); // this is a method to return you the
right item, based on some key comming from the url arguments.
fd.setValueForBinding( item.title(), "filenameForClient");
fd.setValueForBinding(new Boolean(b1),"useDisplayOnlyIfDataExists");
fd.setValueForBinding(new Boolean(b2),"useShowLengthOfDownload");
fd.setValueForBinding(new Boolean(b3),"useShouldDisplayInBrowser");
fd.setValueForBinding( item.projectDocumentObject().documentObject
(), "data");
return fd;
}
The hyperlink all have the action bound to doMyStuffWithURL, and
you add your extra arguments the usual way.

I have someone else's component.
And me thinks you are misunderstanding it and/or misusing it.
So what I have to do is create my complete
url in java code. Normally I use something like componentActionURL
(). However
this component has only:
public WOComponent actionDownloadThisFile()
{
returnDownloadInsteadOfComponent = true;
WOComponent componentToReturn = componentValueForBinding
("action", context().page());
return componentToReturn;
}
There is no component in the html. Just one generic component
that needs to render a url.
So I did this in my java code:
NXFileDownload fd = new NXFileDownload(context());
fd.setValueForBinding( item.title(),"filenameForClient");
fd.setValueForBinding(new Boolean
(false),"useDisplayOnlyIfDataExists");
fd.setValueForBinding(new Boolean
(true),"useShowLengthOfDownload");
fd.setValueForBinding(new Boolean
(false),"useShouldDisplayInBrowser");
fd.setValueForBinding( item.projectDocumentObject
().documentObject(),"data");
OK, that is just nuts. Doesn't that just scream NOOOOOOO at you?
I can hear it from here. ;-)
So now what do I do to render its url?
I was hoping for something like fd.componentActionURL() .. BUT it
doesn't have one?!
This looks like a component that you put on a page and it
generates its own UI ("click here to download" or whatever). You
seem to be trying to bind it to some other link that you have
created. You might be able to torture it into this, but why?
<webobject name="FileDownload"/>
FileDownload : NXFileDownload{
filenameForClient = item.title;
useDisplayOnlyIfDataExists = false;
useShowLengthOfDownload = true;
useShouldDisplayInBrowser = false;
data = item.projectDocumentObject.documentObject;
}
If you really want to not use it like that, you will have better
luck sub-classing it and giving it a UI like that.

How do I do this?
I assume you've a reusable component you're wanting to drop on a
page?
Say I have a component that renders the url that is for the
delete method in that component?
perhaps something like this is what you're after.
-- html --
<webobject name="CanDelete"><webobject name="DeleteAction">...</
webobject></webobject>
-- wod --
CanDelete: WOConditional {
condition = hasDeleteableParent;
}
DeleteAction: WOHyperlink {
action = deleteAction;
}
-- java --
public WOActionResults deleteAction() {
return deleteableParent().deleteRecord();
// or
return performParentAction( "relevantKey" );
}
public YourInterface deleteableParent() {
return parent() instanceof YourInterface ? ( YourInterface )
parent() : null;
}
public boolean hasDeleteableParent() {
return deleteableParent() != null;
}
with regards,
