Flex 3: property data Combobox is not recognized

Hello

Why is the data property Combobox is not recognized?

I have a Simple drop-down list box, in respect of the change of the said event, a function is to be called and under this combobox.data doesn't think?

<? XML version = "1.0" encoding = "utf-8"? >

"< mx:Application xmlns:mx ="http://www.adobe.com/2006/mxml"layout ="absolute">"

mycombobox.setStyle('backgroundColor','#137EC2');
}
}

Hi Kiran,

You should not use the property data in this context. IT, real goal comes in the image when you work / are using itemRenderers and itemEditors.

More on the if(mycombobox.data>1) of the condition will be satisfied not why because your mycombobox.data is equal to the null value and therefore the condition fails.

data

property

data:Object[read-write]

The data property allows you to pass a value to the component when you use it in an item converter or editor element. You use data binding to bind a field of the data property for a property of this element.

The ComboBox control use it listData property and the data property as follows. If the ComboBox in a DataGrid control, it expects the dataField property of the column to map to a property in sets of data and selectedItem to this property. If the ComboBox control is in a list control, it is expected that the labelField of the list to map to a property in sets of data and selectedItem to this property. Otherwise, it sets selectedItem to the data itself.

You do not set this property in MXML.

This property can be used as the source for data binding.

Thank you

Jean Claude

Flex Bug? "embedAsCff: false ' is not recognized by Flex!

I have a few fonts embedded in my Flex application. When I run the application, I get the following error:

warning: incompatible embedded font 'DaxNoCff' specified for mx.core::UITextFormat. This component requires that the embedded font be declared with embedAsCff=false

The font embedded in my fonts.css file looks like this:

@font-face {
    src: url('fonts/daxRegular.ttf');
    fontFamily: DaxNoCff;
    embedAsCff: false;
}

@font-face {
    src: url('fonts/daxMedium.ttf');
    fontFamily: DaxNoCff;
    fontWeight: bold;
    embedAsCff: false;
}

Other fonts that have embedAsCff to the fine, set to true display. Nobody knows the reason why embedAsCff:false is not recognized by Flex?

I think it is embedAsCFF.

Foreign key constraint, not recognized during the synchronization of data with the model dictionary

Hello
Data Modeler is a foreign key constraints do not recognize when synchronizing data with the model dictionary, although the foreign key is there (in the database that a data dictionary is read). I can't find any criterion when a foreign key is not recognized by the Data Modeler. Are there limits to the length of the attribute, or the number of columns in a foreign key, or other limitations which may lead to this behavior not to recognize a fk by Data Modeler? I have columns more than 32 characters. I compared with the fk is recognized by DM, but I can't find anything that indicates why it is not recognized.
I wonder if someone also has constraints of foreign keys that are not recognized in the comparison of data bases and model?
Thank you

ORA-01821: date format not recognized when you use the format TSH:TZM model

Hi all
Running on the Oracle 11 g Enterprise Edition Release 11.2.0.2.0 - 64 bit Production database
I guess I am missing something here... but the following SQL code raises the exception ORA-01821.
```
SELECT to_char(CAST(to_timestamp(SYSDATE) AS TIMESTAMP WITH LOCAL TIME ZONE),'YYYY-MM-DD"T"HH24:MI:SSTZH:TZM') as date_updated FROM DUAL;
```
ORA-01821: date format not recognized
01821 00000 - "date format not recognized".

2013-09 - 04T 13: 24:16EDT
I need to format a date in a date in the correct format with time zone for an Atom (RFC3339) feed
for example. 2013-09 - 04T 14: 11:09 - 05:00
I do not know why the TZH:TZM triggers the error...
Database NLS settings have anything to do with it?

NLS_TIME_TZ_FORMAT = HH.MI. SSXFF AM TZR
NLS_TIMESTAMP_TZ_FORMAT = DD-MON-RR HH.MI. SSXFF AM TZR
Thanks for the help

If you want to change the display format, can you use to_char with the expected format

SELECT to_char (TO_TIMESTAMP_TZ (to_char (sysdate,' YYYY-MM-DD HH), "YYYY-MM-DD HH:MI:SSTZH:TZM"), "YYYY-MM-DD"T"HH:MI:SSTZH:TZM") t1d FROM DUAL;

ORA-01821: date format not recognized in PL/SQL report - 4.0
Hello

I use Apex 4.0 and I have a classic report (return of function application) which allows you to select a date column.
The query runs in the background and gives the result.

But when I run the report on the page, I get the error
```
 report error:
ORA-20001: Error fetching column value: ORA-01821: date format not recognized
```
The values for the column are like this 14-MAR-13, 01-FEB-13, etc... Everything seems to be good.

But I don't know why this error occurs.

Thank you

Divya says:

Yes, this is a database column, and the data type is Date.

The I used to convert the format is to_date(inv_date,'dd-mm-yy').

My format of the Date of the application is "DD-MON-YYYY '.

If the column type is date, then DO NOT use to_date. To format the date, either use the format column (which is strongly recommended) or to_char mask in the query:
```
to_char(inv_date, 'dd-mm-yy')
```
It is not recommended the use of the 2-digit year formats.

SELECT DISTINCT  to_date(TO_CHAR(csactivated,'DDMONRR'||'24:00:00'),'DD-MON-RR hh24:mi:ss') FROM CUSTOMER_ALL

XPS 8700 Fax / Data modem not recognized after mode 'sleep'

I have an internal modem installed pci-e. After the system goes into sleep mode, the modem is not recognized. Resolution is to draw the pci-e card, restart the system, then stop again, re - install the Fax/data modem and it is recognized, until the system goes into sleep or stop mode.

How can I keep the device recognition, didn't have to pull on the map and re-insert/install whenever I start?

When I look at the Device Manager after the mode standby or shutdown, the device will display hidden and not connected to the system.

System BIOS is updated to the current 10 A

Always include the version of Windows in your messages.

You may need to change sleep settings and possibly disable hybrid sleep by using the Windows power options, and/or adjust the power options in the BIOS Setup.

Data store 6.0 VMWare not recognized after the last batch of hotfixes installed on HP custom image

Hello guys,.
Maybe you can help me:
I installed VMWare 6.0 on a server HP ML350 G9 with image OEM offered custom HP, ESXi - 6.0.0 - 2494585-HP - 600.9.3.30.2.
This works perfectly.
Now I am trying to apply the latest available official patch (ESXi600-201507001), but it seems to kill some important VIB
VIBs installed: VMware_bootbank_esx - base_6.0.0 - 0.11.2809209, VMware_bootbank_lsu-lsi-lsi-mr3-plugin_1.0.0-2vmw.600.0.11.2809209, VMware_bootbank_lsu-lsi-megaraid-sas-plugin_1.0.0-2vmw.600.0.11.2809209, VMware_bootbank_misc - drivers_6.0.0 - 0.11.2809209, VMware_bootbank_sata - ahci_3.0 - 21vmw.600.0.11.2809209, VMware_bootbank_scsi - hpsa_6.0.0.44 - 4vmw.600.0.0.2494585, VMware_bootbank_scsi - mpt2sas_19.00.00.00 - 1vmw.600.0.0.2494585

The next time I reboot the server, the data store is not available, no more and I have to do a restore. I suspect that the new bootbank_hpsa is the origin of the problem.
So, how to install the latest patch without losing the data store connectivity?
Thank you

What should work, is to download the latest driver hpsa in the/hpq/latest/esxi-600-devicedrivers Indexand install it just after the connection of the host (prior to restart it). The .zip file contains a bundle off line as well as the .vib file.

& quot; data binding will not be able to detect assignments & quot; warning
new features in Flex Builder 3, Beta 2 (I did not have this problem with Beta 1), I have randomly (it seems) get warnings "data binding will not be able to detect assignments to < property >" for properties that are Bindable. If I run my AIR application while I have these warnings the app will not be able to detect assignments to these properties, as warning says. However do a rebuild/clean removes these warnings and my app then works well, with data binding works as expected. I have not found a way to force this behavior, it seems just occur occasionally during development.

others have this problem?

iTunes not recognizing iphone

Hey guys, last updated itunes is not recognizing my iphone.

Uninstalled and reinstalled iTunes several times, everything is up to date. I also tried the thing of driver device manager update, but the apple usb driver is not present even after I have reinstall and uninstall iTunes, all solutions? p.s Also running windows 10.

TV not recognized by the server-> 40L 73

Hello

My problem is already listed on this forum but I can't find a solution or explanation.

I recorded with a Toshiba account in order to use the "smart" features of my incl. TV services VOD as Maxdome etc...

Whenever I push the button 'cloud' I get the message: "your TV was not recognized by the server. Press OK to re - connect to the server... »

When I press OK, it will start to accept T & C, privacy, user name, password, etc... The connection will work with my current username and password...
But unfortunately he will not stay for the next time.

Call the hotline they suggest to send the unit for repair... I can't believe that there is a problem with my TV... But server.

Any suggestion? May be related to an IPv6 Internet connection?

In addition, even, I would say I'm a fan of Toshiba, my TV's performance are simply bad. When I have the cloud works, it takes two minutes until Maxdome should be started.

And can someone tell me WHY I need to get into the clouds to access my saved content? Or Media Player? This content "offline" should be much more quickly accessible.

Thanks for your help and your comments in advance.

Maybe you should just a few solutions of circumvention of the Commons:
First, you must set the default TV.
Then configure the internet connection once more and then try to connect to the cloud to accept all of the terms and conditions, privacy and other things.

By the way: you should also check if your firmware is up to date. This can be checked here:

Downloaded new itunes now iPod not recognized. Uninstalled and reinstalled. No sign of the driver on the list of devices iPod win 10. Tried the other fixes - what do I do now?

With the help of Windows 10. Downloaded latest version of iTunes (should have been better). Now iPod Nano not recognized. Tried to uninstall and reinstall iTunes without result. Check the list of device driver - no sign of the iPod device driver. Read various tips listed here, but nothing seems to work. How can I get the driver?

Douglas

The 'driver' is here. It is part of the installation of iTunes. When you connect it, the iPod screen indicates it is connected, by showing 'do not disconnect' or 'Connected' or another indication that there is a data connection with the computer? If it shows that the battery symbol, there may be another problem that requires no software and 'drivers '.

If the iPod has a data connection (but he does not appear in iTunes), you can use the procedure to completely uninstall iTunes and associated software components. Can you only uninstall iTunes. It's the Apple procedure, listing the components uninstall and uninstall specific order

Remove and reinstall iTunes and software for Windows 7 and later versions - Apple Support components

After you have uninstalled all parts of the installation of iTunes, download and reinstall the latest version available
