Re: [SPAM] [flexcoders] Animating items in a tilelist when filtering arraycollection
Hi Valdhor, i have sent a new stand alone app to you email valdhorli...@embarqmail.com that does not require any application server and database, just uses xml to store data. hope you can work around with this one.

In the other, the gateway returns data correctly. So the data going in both directions can be exactly the same. But in only one case does the serializer cause an error. I've experimented with a variety of data combinations. But as I say, the results are inconsistent, even with the same data being serialized in both directions. So it doesn't seem to be a data issue - unless something at a deeper level, beyond the application code or the data that is actually sent from Flex or that exists in the database, is actually corrupting or not returning the data correctly. Basically, something inside CF. Perhaps someone else might have seen this? -- Thanks, Tom Tom McNeer MediumCool http://www.mediumcool.com 1735 Johnson Road NE Atlanta, GA 30306 404.589.0560

Then just have a getter defined by the interface that says what the rendered row should look like.

You'll need to wait until everthing is complete and all the properties are set, so you're going to have to pass things back and forth between multiple event handlers. 3) Depth: Since you have no control over the renderers, you don't have any way of knowing whether they're composed of containers within containers, etc. 4) Layout: Presumably, you want to have the text appear in the same order it appears in the columns, and then within the individual renderers. There's no guarantee that your iteration will go from top left to bottom right, so you'll have to record where the text was found and then arrange it in some way that tries to make sense (but may not, depending on what is going on in the renderers). 5) Random surprises from the renderer developers.

[flexcoders] Twitter Feed Within An Air/Flex Application
I've previously made an air application for my university course and my tutor has suggested that I incorporate more live data into it. One of the ways he suggested was to include a twitter feed. I have no experience of using feeds within flex but I think I've managed to get one in. How it works is when users type in their twitter id and click a load button all of their tweets are displayed within a repeater component. They can then click a save button to save their twitter id and whenever they start the application in the future their tweets will load into the repeater component automatically as long as their name has been saved. This may seem like silly question but does what I've described constitute a 'live twitter feed' which is what I've been asked to include or am I missing something?
[flexcoders] Re: Twitter Feed Within An Air/Flex Application
Hi James, If your application automatically displays new tweets, those created after the initial load, than yes; that would be considered live. If however its just taking a snapshot, then no. A starting point would be to refresh the tweets. Having the ability to post tweets, and see them instantly show up, would also make it more live. Other ideas would be IM, chat, or other real-time activities that involve the course; like live test scoring, or something. -TH --- In flexcoders@yahoogroups.com, James garymoorcroft_...@... wrote: I've previously made an air application for my university course and my tutor has suggested that I incorporate more live data into it.

[flexcoders] Need Help With an App Which Produces Live Images
At the moment I have an application which is meant to produce live thumbnail
images of websites. Currently how it does this is a html component (myhtml)
loads websites via it's location property changing from website to website and
upon fully loading of each site a snapshot is taken of the html component and
saved as a bitmap and applied as the source of an image corresponding to that
particular site (abcnewsimage and bbcnewsimage). However I now need to insert
these snapshots within the 'icon' properties of 2 array collections
(myTilelistAArrayCollection and myTilelistBArrayCollection) which act as
dataproviders to populate 2 tilelists (mtTilelistA and myTilelistB).
Basically I need the same images to appear automatically within the tilelists
the way they do in the 2 images as the snapshots are taken by applying the same
bitmaps into the currently empty 'icon' properties of the 2 tilelists i.e. the
icon of the ABC News Item of both array collections must be the same as the
abcnewsimage and appear as it appears and the same for the BBC News Item icon
being the same as the bbcnewsimage picture as that appears.
It should look like the images aare appearing in the tilelist at the same time
as they are appearing in the regular images. What will I need to ut into the
icon properties to do this?
I hope this makes sense and if anyone can help me out it would be much
appreciated. :-)

[flexcoders] Re: Twitter Feed Within An Air/Flex Application
Polling the twitter service every 60 seconds (refresh) would be a way that you could get updates semi-automatically. You're not using RTMP, so you're never going to be really live.

I have an itemrenderer mxml hbox for that column with a repeater for generating multiple linkbuttons based on a xml results set.

Hi Valdhor,
I was doing the same thing for dynamic styling using an xml style file. I am
successful except applying skin files to components. I was trying to keep an

class) and load it at runtime. And based on the linkage name specified in the
XML file, tried getDefinition(name). Got an error which said 'Argument count
mismatch on TickMark(). Expected 2, got 0.'
Can we load a dynamic image or swf like this, so that I can skin components too
with XML and resource file instead of pre-compiled skin swfs. I have specific
need for this, and cant do the CSS/compiled CSS skinning.
Thanks for any help you can offer.
