[flexcoders] Re: Desperate Help! crossdomain.xml
We ran into a similar situation with having the crossdomain.xml policy file in a subdirectory of a site. The phase 3 change that went into affect with FP10.02 requires the root directory of the site to have a meta policy file (policy file for policy files) that allows for the use of policy files in subdirectories. If it is missing then the site-control permitted-cross-domain-policies defaults to master only, causing all other policy files to fail security check. Therefore, the crossdomain.xml meta policy file placed in the root directory will have the following: ?xml version=1.0? !DOCTYPE cross-domain-policy SYSTEM http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd cross-domain-policy !-- The crossdomain meta policy file must be copied to the root of your site -- !-- Allow subsite policy files -- site-control permitted-cross-domain-policies=all/ /cross-domain-policy Then the subdirectory policy files will look something like the following: ?xml version=1.0? !DOCTYPE cross-domain-policy SYSTEM http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd cross-domain-policy allow-access-from domain=YourDomainHere to-ports=80 / !--above is best practice OR allow-access-from domain=* /-- allow-http-request-headers-from domain=YourDomainHere headers=* / !--above is best practice OR allow-http-request-headers-from domain=* headers=* /-- /cross-domain-policy The important part is having the meta policy file in the root directory. Hope this helps, CJ
[flexcoders] Dynamic text flowing
I have a custom component comprised of stacked mx:Text within a

[flexcoders] Re: Trying to underline datagrid header text. How???
Ok.
I'll post any results here once I get'em.
Thanks so much for your input Alex, you've helped me understand a
little more about the renderers.
Thanks again,

When someone clicks the header, a HEADER_RELEASE event is
dispatched, and if you call preventDefault() on the event, the sort
will not take place. You should then go get the data. You can
freeze the screen by putting up a modal popup or some other UI.
Once the data is returned, store the name of the sort and use that
in your renderers to show the underline. You would match against
that name instead of owner.dataprovider.sort.sortField[0].name.
Check the forum archives and search the internet. Someone has
successfully overridden the actual Sort so sortarrows would continue
to work but the underlying collection would not be sorted.

No there isn't a sort applied. I want to override the default
sorting
functionality so the data can be sorted on the server.
Sorry I wasn't clear enough on one of my earlier posts. The sorting
is done on the server to a much larger set of data than what is
displayed in the Flex app. When I call the service and get the
result, which is a subset of the overall result set, it is already
sorted for display.
Hmmm, is there a way to not override the default functionality but
to
just freeze the screen until the new sorted data is returned from
the
server to be displayed? If I can freeze the datagrid so the sorting
on the flex side isn't seen and then unfreeze it when the new data
arrives might work.
Or...
Can I override the default sort to prevent a normal sort just so
the sort arrow remains?
As you can tell I'm just grasping for any work around at this time.
Thanks,

Thanks komentarnya.
Mungkin di milist ini yang belum saya jelaskan lebih detail, tetang
kepentingan dari CV dan dokumen lainnya.
Secara singkat saja,
Kita sedang mengerjakan project tepatnya 3 project besar yang saling
berkaitan, jadi memebutuhkan 3 tim besar.
Kita sudah menyiapkan spesifikasi tim, tapi kita juga ingin melihat dari
sudut pandang berbeda, yaitu dari kemampuan masing2 personal.
Ada 2 penyaringan CV ( dan dokumen lainnya), yaitu penyaringan pertama
akan digunakan manajemen sebagai analisis dan kelengkapan dokumen
project kami, dan setiap pemilik CV akan diberi pengganti .
Penyaringan ke-2 yaitu digunakan untuk keperluan tenaga utama.
Untuk dokumen yang dibutuhkan, saya rasa ngga ada yg aneh.
Karena kelengkapan dokumen tsb memang dibutuhkan oleh pihak manajemen
kami.
Apakah ada dokumen rahasia yang saya minta ?
Sebenarnya simple saja, kalau mau berpartisipasi, tinggal kirim CV dan
kelengakapannya.
Kalau menurut anda salah satu dokumen tsb ada yg ngga boleh di komsumsi

Trace output:

DataGrid(listData.owner).dataProvider.sort is null: true
data.dataField = symbol

[flexcoders] Re: Trying to underline datagrid header text. How???
I believe I got it. I use the added sortEventHandler event listener
to set the style textDecoration to none and the clickHandler to reset
the textDecoration to underline.
private function sortEventHandler
(event:DataGridEvent):void
{
if (event.itemRenderer == this){
event.preventDefault();
}
setStyle(textDecoration, none);
}
private function clickHandler(event:MouseEvent):void
{
setStyle(textDecoration, underline);
}
and it took me way to many hours to come to this conclusion. yikes!
Thanks for your input Alex, it is greatly appreciated.

CJ

You'll need more null checks and what not but that tests to see if
the sort on the collection is sorting on the same field as the column
the header renderer is displaying.

Thank you Alex for your feedback.
So I visited your blog read about renderers, very good info, and
started with your checkbox example. I changed the checkbox to a label
and have it underlining on the click but don't know how to toggle the
underline when clicking other columns. Can you or anyone provide any
suggestions on how I can achieve this? Below is the headerRenderer
custom class.
RgColHeaderLabel.as file:
package
{
import mx.controls.Label;
public class RgColHeaderLabel extends Label
{
import flash.events.MouseEvent;
import mx.events.DataGridEvent;
import mx.controls.DataGrid;
import mx.controls.dataGridClasses.DataGridColumn;
import mx.controls.dataGridClasses.DataGridListData;
private var _data:DataGridColumn;
public function RgColHeaderLabel()
{
super();
addEventListener(click, clickHandler);
}
override public function get data():Object
{
return _data;
}
override public function set data(value:Object):void
{
_data = value as DataGridColumn;
text = DataGridListData(listData).label ;
setStyle(textAlign,center);
DataGrid(listData.owner).addEventListener
(DataGridEvent.HEADER_RELEASE, sortEventHandler);
}
private function sortEventHandler(event:DataGridEvent):void {
if (event.itemRenderer == this)
event.preventDefault();
}
private function clickHandler(event:MouseEvent):void
{
//how do i underline only the clicked header?
setStyle(textDecoration, underline);
}
}
}
Below is your dg.mxml with a modification to the headerRenderer:

[flexcoders] Re: Trying to underline datagrid header text. How???
Well thought I had it licked but not!
It works great until I make my HTTPService call to the Spring
controller on the server to get the sorted result. Just like the sort
arrow the underlining disappears after the service call.
I only show 20 records out of a much larger result set so when
sorting I need to call the HTTPservice again to get the sorted subset
after the entire resultset is sorted on the server. E!
Does anyone have a work around for this kind of behavior? What do I
need to extend/override to keep the sort arrow or in my latest
attempt the underlining?
Any and all help is appreciated.
Desperately,
CJ

[flexcoders] Trying to underline datagrid header text. How???
I am using the headerRelease event in the DataGrid control and calling preventDefault in my header release custom function, which, as you know, keeps the sort arrow from displaying. Therefore, I want to do a less complicated work around and just underline the header text when the column is sorted. Is there a way to underline the header text just for the sorted column? OR Does anyone have a good work around for the ellusive sort arrow. I did notice a post by Alex Harui http://tech.groups.yahoo.com/group/flexcoders/message/121805 that talks about subclassing a collection and either override the sort property or refresh method so the collection doesn't actually sort. Can anyone give some guidiance on this? Thanks much, CJ
