Re: [flexcoders] Flex dataservices paging question
Ward Loockx schreef:
Hello,
I'm trying to use paging on my resultset retrieved from livecycle 2.6.
In my resulthandler I only get 1result in my arraycollection(but the
pagesize is set to 10!) and the count of the arraycollection 3500 (so
in total 3500 results). When I try to loop over the array (he should
automaticly retrieve more items -> said in documentation), I get
*Error: Item requested is not available. A request for the item is now
pending.
*
I've been googling and saw that it was a bug toward 2.4 of livecycle
but running 2.6... And why am I just retrieving one result instead of
10(my specified page size)?
Here is some extra code
The looping in teh resulthandler
* private function searchResult(evt:ResultEvent):void
{
for each(var obj:Webcam in foundCams)
{
trace("-->"+obj);
}
}
*and the initializing of the data service object
* searchService = new DataService("search");
var myrtmp:RTMPChannel = new RTMPChannel("my-rtmp",
"rtmp://*:2038");
searchService.channelSet = new ChannelSet();
searchService.channelSet.addChannel(myrtmp);
searchService.addEventListener(ResultEvent.RESULT,searchResult);*
Thanks,
Ward
Looks like I'm trying to populate my own component and when an item
isn't found it throws an ItemPendingError where I should add an
responder to...
I'm retrieving the search result in my search class and then use a
component to show my results (later with next/previous button)... I'm
calling the creation of the component when the resulthandler of the
searchresult is called. I give my arraycollection as parameter to the
component to create the results. But how can I change my code that the
component can handle the errors when an item isn't found and continues
populating?? Can somebody give some examples how this is done? Looks
like the datagrid component can handle it by itself, how should I build
in that support in my component?
Thanks!
RE: [flexcoders] Flex dataservices: fill vs asynctoken
Asynchronous methods like fill() return an AsyncToken instance which you
can use to add custom data to it (i.e. mark that ypu invoked a fill operation).
In the result handling function the AsyncToken is available again, so you can
add additional logic to your result handler, e.g.
private function
resultHandler(event:ResultEvent):void
{
switch (event.token.kind)
{
case "fill":
...
case "delete":
...
}
}
AsyncToken is a dynamic class so you can add whatever properties you
like.
Another use case of AsyncToken is to add responders to it - this allows
you to dynamically setup result/fault handling functions:
var
token:AsyncToken = ds.fill(collection);
token.addResponder(new ItemResponder(resultFunction, faultFunction,
"fill"));
and
then
private function resultFunction(result:Object,
token:Object):void
{
// result usually is of type ResultEvent,
// token is the third parameter passed to the ItemResponder
constructor
if (result is ResultEvent)
{
...
}
}
private function faultFunction(result:Object,
token:Object):void
{
// result usually is of type FaultEvent,
// token is the third parameter passed to the ItemResponder
constructor
if (result is FaultEvent)
{
...
}
}
Dirk.

Hi,
I’m new to flex dataservices
(using WebORB), and I like to know what’s the difference
between:
ds = new
DataService("contact");
ds.fill(contacts);
and
ds = new
DataService("contact");
var token:AsyncToken =
AsyncToken(ds.fill(contacts));
token.kind =
"fill";
Thanks!
Jonas

RE: [flexcoders] Flex dataservices:
Mike,
The fact that the error said the send failed means that
perhaps the RTMP channel isn't running... so I'm guessing something went wrong
on starting the web application. Most likely the configuration was invalid.
Can you look at the server startup output (perhaps in the console window
itself or in the web application logs... depending on how you launched Tomcat)
for an indication as to whether there were such errors, and, hopefully, a clue
as to what is wrong with the config?
Pete

dataservices:
I have read some of the posts on issues similar to this one.Especially
the Hank Williams and Peter Farland exchange. However, thisproblem is
different enough that their posts did not help.I am trying to adapt the
samples examples to work with an app I amdeveloping. (BTW, all the samples
work on my Tomcat test serverrunning on Windows.)The issues I have
is a failure when I try to a fill on a DataService.I've attempted to
simplify the configuration files but I must haveleft something out. Anyone
who has some experience in this area mayeasily spot my mistake but I have
tried all the changes I can think ofwithout any change in the
result.Here are the gory details:// This is the script that
creates the data service and tries topopulate the orders
arraycollection.//
