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,
