[flexcoders] BrowserManager crossdomain issues
Hi All, I'm trying to host the html-template files provided by Flex Builder (including all necessary JavaScript) on one domain (www.mydomain.com) and the embedded SWF on another (swf.mydomain.com). Now, even though I call Security.allowDomain(*.mydomain.com) in my Flex app and allowScriptAccess=always in the embedding html, FlashPlayer complains about a SecurityViolation in flashlog.txt. It actually happens as soon as I hit the browser's back button. Firebug reports: uncaught exception: Error calling method on NPObject! [plugin exception: Error in Actionscript. Use a try/catch block to find error.]. The exception gets thrown in the setTitle function in history.js. Crossdomain files don't seem to be the issue, they're set up and working fine for other content. I cannot really find any reference of others who tried this before, does anyone know if it is actually possible at all to host the history related JavaScript in a different domain than the SWF?

Hi Alex, This is a SWF compiled with Flex SDK 3.3 running in Firefox 3.5. The BrowserManager code works fine when the HTML/JavaScript and SWF are hosted in the same domain, only separating them breaks it.

Both domains are https. Yeah, I'll use the debugger but I get the impression that this is a Flash Player security restriction. -David --- In flexcoders@yahoogroups.com, Alex Harui aha...@... wrote: Is one domain https and the other http?

[flexcoders] Re: Remove mx:Binding
Hi Amy, as far as I know there is no way to remove a Binding that has been created via an mx:Binding tag. To be able to remove Bindings, you can keep track of ChangeWatchers that have been created in AS (instead of MXML) via BindingUtils.bindProperty/bindSetter and remove them with a call of ChangeWatcher.unwatch. E.g. Store your ChangeWatchers in an array - unwatch and remove one or all of them when needed. Example: var watchers : Array = []; var cw : ChangeWatcher = BindingUtils.bindProperty(...); watchers.push(cw); ChangeWatcher(watchers.pop()).unwatch(); If you can change the code of your super class, use BindingUtils instead of mx:Binding and remove the ChangeWatchers in the subclass. -- david keutgens software consultant cynergy australia web | http://www.cynergysystems.com --- In flexcoders@yahoogroups.com, amywongwy amywon...@... wrote: Hi, Is there a way to remove the mx:Binding tag?

[flexcoders] Re: Applying metadata in the middle of mxml - is it possible?
--- In flexcoders@yahoogroups.com, per.olesen [EMAIL PROTECTED] wrote: Hi, Basically, I would like to apply some (of my own) metadata to a component instance inside the mxml. Like this: ?xml version=1.0 encoding=utf-8? mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; mx:ApplicationControlBar mx:Metadata[MyMetadata]/mx:Metadata mx:Button id=foo label=Blah/ /mx:ApplicationControlBar /mx:Application And then only have the [MyMetadata] applied to the foo button instance. Is this possible? Placing it there makes the compiler bark. I guess this is due to the fact, that mxmlc will put it before a class definition. I then tried something like this: ?xml version=1.0 encoding=utf-8? mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; mx:ApplicationControlBar mx:Script[MyMetadata]/mx:Script mx:Button id=foo label=Blah/ /mx:ApplicationControlBar /mx:Application but this made the compiler bark too :-) about metadata requiring an associated definition. And of course it is right. My guess is the mxmlc compiler is translating the above to something like: acb = new ApplicationControlBar(); [MyMetadata] b = new Button(); acb.add(b); and of course then it is wrong with the metadata element there. Am I right? Can I do it some other way? I came up with this: ?xml version=1.0 encoding=utf-8? mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; mx:ApplicationControlBar myns:MetadataButton id=foo label=Blah/ /mx:ApplicationControlBar /mx:Application and then have a component MetadataButton.mxml with this content: ?xml version=1.0 ? mx:Button xmlns:mx=http://www.adobe.com/2006/mxml; mx:Metadata[MyMetadata]/mx:Metadata /mx:Button which works! But the MyMetadata annotation will change on the various buttons. So I would like to inline it, like this: ?xml version=1.0 encoding=utf-8? mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; mx:ApplicationControlBar mx:Button xmlns:mx=http://www.adobe.com/2006/mxml; mx:Metadata[MyMetadata]/mx:Metadata /mx:Button /mx:ApplicationControlBar /mx:Application but this makes the compiler bark again. Any help? Hi Per, You can tell the compiler to accept custom metadata tags by using the keep-as3-metadata compiler flag. You'll have to add it to your compiler options. See http://livedocs.adobe.com/flex/3/html/help.html?content=compilers_14.html for details. I hope that helps. -- david keutgens software consultant cynergy australia web | http://www.cynergysystems.com

I have the requirement for a button which has text writton on it like
the spine of a book, so rotated clockwise by 90 degrees.
I have been looking at threads about text rotation but haven't found
anything which exactly matches my requirement. Anyone know how to do
this in Flex 2? Or know of a component I can grab which does it?
TIA
Simon
Hey Simon,
a very simple solution would be to create a custom Button class that
extends mx.controls.Button.
In that class you could override the createChildren method to rotate
the internal textField (it's a protected member of the Button class
that is used to render the button's label).
Example:
override protected function createChildren():void
{
super.createChildren();
if (textField)
{
textField.rotation = 15;
}
}
Note that this will probably mess with the component's measurements.
You might have to override the measure method as well to make sure
that your button component delivers correct sizes.

Hi All
This is somehow regarding the question I have asked few weeks back.
Unfortunately I have to stop this task at that time and now need to
work on that. My need is that I have some entries in the List as an
arrayCollection and there is text input box and I like to have list to
filter the data as soon as user starts typing text. I have attached
the so far developed code. I need as soon as user types On, the list
below should only show first entry which is 'One-Device'. I attached
the code but it is not working as I want. This is going to be just my
dummy working prototype and once this module has been made working
then i am going to merge this module into my Main Project.
Also if anyone has any better idea about how to figure this thing out
that will be great and instead of arrayColection if we can achieve the
same function laity that would be helpful too.
Thanks a lot

--- End forwarded message ---
When a collection gets filtered, the filter function is applied to
each item of a collection separately. So the passed parameter for the
filter function is always an item of your collection. In your case the
collection contains strings. The filter function receives the string,
all you have to do in the function is to compare it to your filterText
string.
To do that Josh casted the passed parameter as a string to compare it
to the filterText variable.
