view method not calling
Anyone have ideas or comment on what I might be doing wrong here. I
have a velocity view that creates many checkboxes pending the number of
result sets returned from a dbase query. The getter method in my
webwork action is called when the page is loaded but the setter (which
I expect to be called for each checkbox on submittal so that I can
collect which checkboxes are checked) isn't.
--- my.vm
#foreach ( $set in $toolsList )
<input type="checkbox" name="$toolItem($set.name)">$set.name
#end
--- webwork action
// gets called when view page is loaded
public String[] getToolItem() { return items; }
// I thought should be called when the form is submitted, but doesn't
public void setToolItem(String[] tools) {
this.items = tools;
}
Any help much appreciated.

I guess I'm confused then, because at one point you said $toolItem was a
method. If it's a method, then there has to be a object containing that
method. If it's not a method, then it's an object, and the above isn't
syntactically correct (I think).
Ah well :)

it works for loading (i.e. rendering the html)? if so, then velocity has
done it's job, afaict. if the VTL (velocity template language) that you are
showing us is rendering properly to HTML (i.e. no spurious $references in
the output), then sounds like a question you should ask on webwork's list.
remember, velocity is merely a template language, not a framework. it
doesn't really know anything about "submitting" things.

the basics of velocity are as follows:
put an instance of com.foo.Bar in the context w/a key like "bar"
render the object in the context as
$bar
and the output will be equivalent to myBar.toString()
if you wish to render the result of one of myBar's other methods, do things
like:
$bar.whatever() (calls myBar.whatever() and renders result)
$bar.blah (typically calls myBar.getBlah() and renders result)
#set( $bar.blah = 'ugh' ) (equivalent to myBar.setBlah("ugh"))
if these don't work or fit your situation, then i strongly suggest asking th
e webwork list where people will be more likely to understand what you are
trying to do.

I have a webwork action that returns this velocity view and I have
get/setToolItem() methods in it. So if I'm using it wrong, it seems to
work, at least for loading the page view, but not submitting it.

No, I mean just like I have it above. It works like that, but I can
tell from all the reactions I'm using it wrong. I don't understand what
the reference name should be I think.

You're saying that $toolItem() is the method to be called, but with what
object would it be called? You have it all by itself:

Do you mean ${set.toolItem} or something like that?

But as I have below, $toolItem() is the method to be called, and when
the view loads, the getToolItem is called, but on submittal,
setToolItem doesn't get called. So if you thought getName was the
method as you have above, what was $toolItem as you have above?

I'm not quite sure what you are asking, but above,
$toolItem($set.name)
is missing the method to be called. I would expect something like
$toolItem.getName($set.name)
or similar.
