Re: Tap 4.1.1 problem: async direct link returns empty ajax response

2007-04-13 Thread Matt Larson
Sorry for the long interval on this discussion--needed time to try to 
understand this problem a bit more.  I am wondering if Jesse or anyone 
else can shed a little more light on the empty ajax response problem I 
am having, which is a showstopper for my app.


Using the example below (div jwcid=[EMAIL PROTECTED] ) did not work to add 
the div1 component to the list of components returned by 
getPage().getComponents(), which is why the 
page.components.div1.clientId expression fails.  What I found was that 
@Any components are not added to the component list if they are inside 
components themselves.  If I put an @Any component on the main container 
page with an ID, it showed up in the page.components list, but not if it 
was within my component. 

So I guess the question is, is there a way to get the div 
jwcid=[EMAIL PROTECTED]  component to show up in the page.components list? And 
if it did show up there, would it be found in the list that is returned 
by the _cycle.renderStackIterator() in the DojoAjaxResponseBuilder class 
that I think is doing this work? I see that the method


boolean contains(IComponent target, String id)

looks through the list returned by renderStackIterator() to try and find 
a matching clientId, so I guess that is what is failing in my case.


Also, I am still wondering why this works so nicely when I go directly 
to the containing page (it's my Home page) but not if I use a DirectLink 
with a listener to update some values in my Home page and then rerender 
it?  Is there a call I can make to ensure that the Home page thinks it 
was called as Home.html rather than through a DirectLink?  I think it 
needs to do some kind of setup that it doesn't do via a DirectLink.


Thanks for the help,
Matt

PS. Some named components within other components did show up in the 
page.components list, such as a @For component I used in my .jwc file to 
see the page.components list:


component id=listComponents type=For
   binding name=source value=ognl:page.components.keySet()/
   binding name=value value=ognl:myComponent/
/component

Searching through the list archives a bit, I saw a few suggestions that 
this was related to the fact that @For extends the FormComponent class, 
which sounded plausible but I did not experiment with this enough to 
confirm.

No things should still work the same with 4.1.1. .(but upgrading might
be a good idea either way)

The error you got means that you don't have a component defined in
your page with an id of div1. Your example before on how you were
defining your div blocks was incorrect and I provided an example of
how to do it...ie :

div jwcid=[EMAIL PROTECTED] 

It'll work if you define your block that way.

Hi Jesse,

I did try this approach previously, thinking OGNL would use the Map key
as a property like in your example (I think that's what it's doing in
your example?).  But following your example very closely, I get this
exception:

Unable to read OGNL expression...source is null for getProperty(null,
clientId)

(source is
updateComponents=ognl:{page.components.div1.clientId,page.components.div2.clientId}) 



I think was partly the cause of my confusion before :).  I couldn't see
how that expression could work, and it appears to be dying at the
div1/div2 step.

Now I'm suspecting I need to upgrade to the latest Tap 4.x source and
the latest OGNL, which I know you have done a lot of work on.  Do I need
those to make your example work?

Thanks again,
Matt

longer returns anything. The pagination works using the standard kind of
start from parameter, which calls a listener that simply does
setStartFrom(int startFrom) and then lets the pageBeginRender() method
calculate the objects to display.

I do know the reason that the ratings no longer show the updated
graphic--the AjaxResponse just returns empty tags, with no errors
reported at all (had a look at this with firebug):

ajax-response/ajax-response

The actual link is firing just fine, and all of the server side
processing happens as my logs show. It's just that the ajax response is
empty when it should include new HTML for the divs to be updated.  It
seems like there is some kind of setup that happens when you go directly
to Home.html and click the rating link, but not when I've gone to the
home page via a DirectLink.  I cannot see what would be different, since
my pageBeginRender() method is called, and everything else happens just
like it should in the component and in the page.

If anyone has run into this before or has an idea regarding what this
might cause an async DirectLink to return nothing in some cases, please
let me know.  The pagination is a major part of my app, and users need
to be able to submit ratings no matter which page they are on, so I am
kind of dead in the water until I get this fixed.  Next step is to spend
quality time with the source code, but if anyone has a better idea
before I take that time...

Cheers,
Matt
