[flexcoders] DataGridColumn backgroundColor bug?
Hi guys, This seems like an awfully simple thing for nobody to have picked up before, so hopefully someone can point me in the right direction as to what I'm doing wrong. I have gone way heaps hardcore and simplified the issue to the following using SDK3.2: With either showHeaders="false" or headerHeight="0" the code is generating the following error found in DataGrid's drawColumnBackground function: TypeError: Error #1010: A term is undefined and has no properties. at mx.controls::DataGrid/drawColumnBackground()[C:\autobuild\3.2.0\framewor\ ks\projects\framework\src\mx\controls\DataGrid.as:3012] at mx.controls::DataGrid/drawLinesAndColumnGraphics()[C:\autobuild\3.2.0\fr\ ameworks\projects\framework\src\mx\controls\DataGrid.as:3311] at mx.controls::DataGrid/drawLinesAndColumnBackgrounds()[C:\autobuild\3.2.0\ \frameworks\projects\framework\src\mx\controls\DataGrid.as:3207] at mx.controls::DataGrid/updateDisplayList()[C:\autobuild\3.2.0\frameworks\\ projects\framework\src\mx\controls\DataGrid.as:1506] at mx.controls.listClasses::ListBase/validateDisplayList()[C:\autobuild\3.2\ .0\frameworks\projects\framework\src\mx\controls\listClasses\ListBase.as\ :3280] at mx.managers::LayoutManager/validateDisplayList()[C:\autobuild\3.2.0\fram\ eworks\projects\framework\src\mx\managers\LayoutManager.as:622] at mx.managers::LayoutManager/doPhasedInstantiation()[C:\autobuild\3.2.0\fr\ ameworks\projects\framework\src\mx\managers\LayoutManager.as:677] at Function/http://adobe.com/AS3/2006/builtin::apply() at mx.core::UIComponent/callLaterDispatcher2()[C:\autobuild\3.2.0\framework\ s\projects\framework\src\mx\core\UIComponent.as:8628] at mx.core::UIComponent/callLaterDispatcher()[C:\autobuild\3.2.0\frameworks\ \projects\framework\src\mx\core\UIComponent.as:8568] Line 3012 is: var xx:Number = columnHeader.rendererArray[columnIndex].x There appears to be no rendererArray. Can someone shed some light on this? Is it something fixed in 3.3 (which is something I'm unable to test at this point)? MrB
[flexcoders] Re: specify services-comfig.xml in either MXML or AS?
It's actually really simple (at least for the most basic implementation)
to get rid of services-config.xml and the need for the -services
compiler argument. I've had no problems using it with amfphp or granite.
In the Application's creationComplete() I have something along the lines
of
channelSet = new ChannelSet();
var uri = "http://path.to.your/amfphp/gateway.php";;
channelSet.addChannel(new AMFChannel("whatever", uri));
And I pass the channelSet to Services.mxml as a bindable variable.
Within Services.mxml:
http://www.adobe.com/2006/mxml";
xmlns:cairngorm="com.universalmind.cairngorm.business.*">

[flexcoders] Re: Trigger DateFormatter bindings
Hey TH,
I'd tried binding the formatString but I hadn't considered reinstantiation.
Thanks. Of course I was hoping for a panacea for all my problems without any
code whatsoever. :P
This actually relates to a larger problem regarding dynamic resource
switching that I'd got no help on before, and this is the latest in a series of
kludges to get there.
Thanks again,
MrB.

[flexcoders] Trigger DateFormatter bindings
Hey guys, Is there a way to trigger the binding on all related items when changing the DateFormatter's formatString? eg. becomes MMM, via actionscript in the following: I'd prefer not to be manually injecting the new format into each of the text objects every time. Regards, MrB.
[flexcoders] Re: DateFormatter and dynamic resource management errror
Maybe all this will help someone else here looking for a solution to
this problem (and maybe some kindly bots will run across it at some
point too). In short, you have to compile your own SWCs for each of the
languages, and not just the resource library SWFs every other
instruction set tells you about. This means finding out on your lonesome
all the translations for days of the week and months of the year, and
anything else pertinent like date and currency format defaults. The
steps are:
1) use the copylocale to copy the en_US files to your new language
directories.
2) edit the .properties files located in your equivalent of
C:\Program Files\Adobe\Flex Builder
3\sdks\3.2.0\frameworks\projects\framework\bundles\es_ES\src. The
dayNames and monthNames key/value pairs are located in
SharedResources.properties
3) recompile the framework_rb.swc file. From within C:\Program
Files\Adobe\Flex Builder 3\sdks\3.2.0\frameworks\ I used the following
command (taken from the build.xml script, which I'm still struggling to
get working - seriously damaging my cred).
compc
-locale=es_ES
-output="locale/{locale}/framework_rb.swc"
-include-resource-bundles SharedResources collections containers
controls core effects formatters logging skins states styles utils
validators
-source-path="projects\framework\bundles\{locale}\src","projects\framewo\
rk\src"
-external-library-path="libs\player\9\playerglobal.swc"
4) from your project's root directory, re-run your language compiler for
each of the languages. Again using Spanish as an example, use:
mxmlc
-locale=es_ES
-source-path=locale/{locale}
-include-resource-bundles=LanguageResource,SharedResources,collections,c\
ontainers,controls,core,effects,formatters,logging,messaging,rpc,skins,s\
tyles,utils
-output=src/Resources_es_ES.swf
Formatters will now do their internationally spelled magic. Hopefully
this will all become useless very soon, with Adobe just handing over all
these languages by default.
A man can dream. A man can dream.

The copylocale that I used earlier to create the resources seems to do
exactly that: copies. It doesn't actually create a proper locale for all
those places. So "January" in en_US is still "January" in it_IT when,
according to Babelfish, it should be "Gennaio" etc. etc.

[flexcoders] Re: Need help- cannot insert multiple statements in one SQL transaction.
Okay...
1) use a synchronous connection as async won't work for transactions.
2) yep, use transactions
3) put your statements in an array, not a semi-colon separated string
4) here's the key part of the code I use
connection.begin();
for each (var sqlString:String in sqlArray)
{
statement.text = sqlString;
try
{
statement.execute(-1);
}
catch(error:SQLError)
{
connection.rollback(responder);
}
}
connection.commit(responder);
connection.close();

[flexcoders] Re: DateFormatter and dynamic resource management errror
Okay, I have what I suppose is a solution to this, but I'm still short a coupla
answers.
1) I ran the resource-bundle-list option again on my application
mxmlc -locale= -resource-bundle-list=myresources.txt
-include-libraries+=..\libs\CairngormWithExtensions.swc app.mxml
which came up with:
CairngormMessages LanguageResource SharedResources collections containers
controls core effects formatters logging messaging rpc skins styles utils
The difference is the SharedResources and formatters, which wasn't in the
original.
2) I recompiled the resource bundles (skipping CairngormMessages, which I'm not
using) over the 15 languages. ie.
mxmlc -locale=da -source-path=locale/{locale}
-include-resource-bundles=LanguageResource,SharedResources,collections,containers,controls,core,effects,logging,messaging,rpc,skins,styles,utils
-output=src/Resources_da.swf
So now it doesn't fall over on MMM or .
However, I have but face. Also, I'm about to make some assumptions... The
copylocale that I used earlier to create the resources seems to do exactly
that: copies. It doesn't actually create a proper locale for all those places.
So "January" in en_US is still "January" in it_IT when, according to Babelfish,
it should be "Gennaio" etc. etc.
What can I do about this?
Where can I get proper versions of these locales?
Is there a way to get the names from the operating system and apply them to
DateBase or is this already happening and I just can't see it because I'm
running an English machine?
Danke for any light you can shed on this.

[flexcoders] Re: Making ComboBox stay open after item select?
Still not too much to do on that. All the functionality appears to be in
the close function. I've kludged up this to do what you want. There's a
"_calling" variable in there as the close function gets called twice on
every change (for reasons I don't care to examine) that'll allow it to
dispatch the change event once per frame.
package
{
import flash.events.Event;
import mx.controls.ComboBox;
import mx.events.ListEvent;
public class ComboBoxNoClose extends ComboBox
{
private var _calling:Boolean = false;
public function ComboBoxNoClose()
{
super();
}
public override function close(trigger:Event = null):void
{
if (trigger != null)
super.close();
else if (dropdown != null && !_calling)
{
_calling = true;
dispatchEvent(new ListEvent("change"));
callLater(function():void { _calling = false} );
}
}
}
}

[flexcoders] Re: Making ComboBox stay open after item select?
I'm by no means on Alex's level of Flex knowledge, but a Button combined with a
Menu component would work too. You wouldn't get into resizing issues and you'd
still be able to do styling without resorting to UIComponent first principles.

[flexcoders] DateFormatter and dynamic resource management errror
Hey guys,
I have a Flex 3 app that employs dynamic resource management - pretty
much a cut-n-paste job from the Adobe sample - with the ComboBox to
switch languages. I did all the copylocale rigmarole and it's all
working perfectly with the languages I've set up.
However, when I try to call a DateFormatter with a full month (MMM or
) in the formatString it crashes and burns with the following error:
TypeError: Error #1009: Cannot access a property or method of a null
object reference.
at
mx.formatters::DateBase$/http://www.adobe.com/2006/flex/mx/internal::ext\
ractTokenDate()
This is probably referring to the DateBase.monthNamesLong array;
formatting is not an issue with M or MM. Am I perhaps missing something
in the creation of my resource files? This is a sample of the command I
used:
mxmlc -locale=es_ES -source-path=locale/{locale}
-include-resource-bundles=LanguageResource,collections,containers,contro\
ls,core,effects,logging,messaging,rpc,skins,styles,utils
-output=src/Resources_es_ES.swf
But it even dies when the locale is set to en_US.
Help? :)
