Why is it necessary to use the tag can be bound

Hello, I am working with some simple data binding concepts.

I defined a Combobox


< mx:ComboBox id = "FirstCombobx".
dataProvider = "{asArray1}" >
< / mx:ComboBox >


To provide data, I use a table

public var asArray1:Array = ["state1', 'state2',"State3"];


It works fine, I mean it shows data on the combobox control, now please tell me why it is necessary to use the tag can be linked with table.

[Bindable]
public var asArray1:Array = ["state1', 'state2',"State3"];

Thanks in advance.

Hello

If you write a tag bindable and change this variable it will reflect automatically whenever you have assigned to this variable. Here is therefore the combobox will change each time you change the table not the inside of objects.

I hope this helps.

    Hi SSB,

    Are using your 11.1.1.6.1 version? If Yes, then you need to add the name of your servlet in 'excludeURL' list of comments ReqAuthConfig.xml or 'Authentication filter application' in the Web.XML as this filter request you send. This is a new filter, they added in this version.

    I hope this helps.

  • When you use the NI-CAN Transmit sample receive the same Harbor; can a virtual CAN channel (RCA or 257) be used?

    I work for a company that produces and transforms electric parts. We strive to get in remission at nine of the ECU, experiences, Instrument clusters etc. I'm trying to learn how to use LabVIEW to write commands and read the data on the CAN bus. I have downloaded the NI-CAN driver. I am currently 'play' with the same reception Port.VI show in the basic frame of the finder example API folder OR. I am not able to send the number in the data to write the table that it be read by the ncReadNet Mult .vi. When I put the parameter to 'Pending entries reading' the ncGetAttr.vi returns a 0 to indicate that there are no frames to read. As a result, the Mult.vi ncReadNet does not run.

    I don't have any connected equipment, I use the virtual CAN channel CAN256. Is this the reason why I can't get data frames in my queue for the Mult.vi ncReadNet to read?

    When you use the NI-CAN Transmit sample receive the same Harbor; can a virtual CAN channel (RCA or 257) be used?

    CAN carry 256 and 257 are connected to eachother through software.  When you write about 256, you can read the data on 257 and vice versa.  I think the example you mention is a writing and reading on the same port, but what you want is to probably to make a copy of this VI, in order to run two at once, where it opens 256 and the other opens 257.  Then, when you write one that you will see on the other.  I think you might be able to use the test panel CAN too read an and use the example of the other.

  • NULL pointer exception when you use the tag ahref

    Hello
    I am writing a file html for the file adapter. Inside the transformation, if I understand ahref* tag, I still get null pointer exception and a 0 KB file is written.

    Hello
    The custom XSD file is not necessary.
    Looks like it's a bug in file 10.1.3.4/10.1.3.5 adapters - it works very well in 11g.

    Whenever there is "a href" tag in the xml support to write to the file, the file adapter tries to get the content of the url real in 'a href' and written to the output file. When I try with any url (say http://www.google.com), the content of google.com is written in the file. If this URL is not accessible (for example http://foo.bar), then you get the null pointer exception. In your case, I think the URL that you are using the payload, is not accessible from your box of soa, or is not a valid URL.

    As a work around 10.1.3.4, I was able to create the XHTML file as follows:
    1 change the link partner of file adapter to use opaque scheme.
    2. in an assign operation, affect the load XHTML to a string variable using ora:getContentAsString ().
    3. Add a java embedding base64 encode the string as follows and assign to the entrance of the file adapter invoke:
    (HTMLString is the string from step 1 variable, InvokeWriteHTML_InputVariable is the input variable to the call on the file adapter operation)

        
        
          
        
    

    4. call the file adapter using the input variable in which is written the value encoded in base64.

    you could use the workaround above or rethink your design (if you want to create the XHTML file using bpel only or other means).

    Hope this helps,
    Kind regards

  • Why all my keyboard shortcuts use the 'Alt' key instead of the ' CTRL '? I use Windows 7 and Firefox 5.0.1.

    I recently downloaded Firefox 5 and noticed that all my keyboard shortcuts by default using the 'Alt' key instead of the 'Ctrl' key (so, for example, open a new tab is Alt + T instead of Ctrl + T).

    I noticed that this applies even to copy and paste in Firefox (Alt + C and Alt + P is the only commands that work).

    No idea why this is happening? I am running Windows 7 and Firefox 5.0.1.

    I had this problem. I found that a roaming profile directory has been installed which contained a user.js file in which changed the hotkey of CTRL ALT.
    I deleted the profile folder a name randomly in c:/Users / [myuser] / AppData/Roaming/Mozilla/Firefox/Profiles and then I stuck to that of c:/Users / [myuser] / AppData/Local/Mozilla/Firefox/Profiles.

    This bad user.js file was some other parameters, including the definition of the user agent string
    "Mozilla/5.0 (X 11;" U; Linux i686; en-US; RV:1.0.0; (Salut, maman) gecko/20020604 "

    The user.js file is (or similar to) those listed here: https://www-archive.mozilla.org/unix/customizing.html

  • Why am I unable to use the LR5 comments section?

    Why can't I access the comments section in the 5 Lightroom library module? I've been using elements and they have a section of information that I can leave notes on each image. Why not Lightroom?

    Hi make piper.

    I assume you mean in the 'Comments' Panel in the library on the right side module. These comments are supported only for images that are synchronized on Lightroom Mobile. Otherwise, you get the message "comments are not supported here." There is more than one type of social media functionality.

    If you want to type noted that are associated with your image, you will be better off using the metadata Panel. The default metadata appears in general but there is a drop-down menu next to the header which will allow you to choose a variety of other areas. You can use something like "Caption" or "Description" to add notes to your heart's content.

  • Using the tag &lt; del &gt; text?

    Hello

    I have blocked applied to several words in a block of text. Know that < del > is the HTML5 tag to use, but I can't seem to apply to the expression in the text block. How can I request < del > just a few words so that it looks so:

    A normal text and some barand more normal?

    Thank you very much!
    Tim

    Hello

    There is no direct way to do it in Muse. You can use this workaround:

    1. Create a character style called del
    2. Apply it on the range of text you want to block
    3. In the property Page > metadata > HTML forthe section, add extract next

  • How to use the tags assigned elements 10 in bridge?  (more than 50,000 photos marked)

    I have a vast catalog of Photoshop Elements 10 with tags assigned to about 60 000 photos.    How I not use the latter in bridge?

    Not familiar with the Organizer, does the same thing as Photoshop Elements?  How that they store tags?

    Elements and Lightroom store tags in a database.

    Bridge and Windows Explorer stores the tags on the image.

    So for Elemennts to work in bridge tags you write tags to the image with keword tag and properties file-write to photo information.

    If you work with a network of you is an entirely different set of problems to establish so that everyone can see the keywords entered by a user with the bridge.

  • Error returned (sometimes) when you use the tag &lt; cfxml &gt;

    I have a problem when you use the < cfxml > tag, its seems error when I try and view the XML over a certain length, because it works for some of my folders and others do not.  Is there a known displaying stuff in the cfxml tag size limit?

    Here is my code, I don't know how to move forward on this issue. Well, any help would be apprciated.

    Right.

    It is therefore being truncated when it is read in the DB.  Nothing to do with CFXML.

    Looks like it is hitting the size of the Long text buffer (which by default is 64 KB).  Increase this value (in your DSN settings, advanced).

  • How to use the tag &lt; HTMLAppletElement &gt;?

    Hi, I am using the element in my WebWorks project, but I couldn't. Anyone know how to use it?

    I found the element here, but there is no example.

    This is part of my code:

    
    

    Hello

    I can't speak much for other browsers, but I've been digging more into the side WebWorks/BlackBerry 10 of things and I got oblivion earlier.

    So that the element can run a Java Applet, Java Runtime must be present on the operating system which is not present on BlackBerry 10. If we support the element in a number of tracks, run the Java Applets is not one of them due to the missing.

    It looks like there may be some security settings on the browser, you need to allow Java on your desktop browsers, where you have installed Java Runtime, run the value, but I don't know exactly where it is.

  • Use the two CAN API

    Hello

    I develop an application that communicates with a microcontroller.  I would like to use the API to frame for a setup where I can send commands and get the answers and want to use the API channel for a mode where I'm simply followed the messages I get from the microphone.

    I have a state machine where I starts with the opening of the frame API, have some different States I'll in that use the appearance of the request/response of the API framework, then a State that closes to the API of frame and opens the Channel API.  The problem I encounter occurs when I already closed the frame API and began playing with the API channel work.  When I click the monitoring button stop, I leave the while loop, who read a message defined in the DB can (havn't had in fact he still read the data) and run the Clear.VI Channel API CAN I get the following error.

    Error - 1074388720 CAN Initialize.vi

    Possible reasons:

    NI-CAN (Hex 0xBFF62110) you can use the frame API and Channel API simultaneously on the same interface (for example CAN0).   MAX tools use the channel API.  Soultuon: Use a different interface with each API.

    I need a way to get around this and I'm not sure why the raster API is not pretending to be closed, especially since I was a State in my state machine to close the frame API before you start using the channel API.

    If anyone has any suggestions please let me know.

    Thank you

  • Why sierra unlocking allowed to use the Apple Watch as a key?

    I do not understand why they have restricted sierra unlock just the watch.

    my iPhone is always in my shirt pocket and I unlock it with my fingerprint as I do with my ipad pro. The phone is used every day with apple pay so close communication is not a problem and so when my phone is close to my computer, my computer must unlock if I touch my finger on the button home...

    It is such forgetfulness obvious it may just be an oversight by Apple and they must have a good reason for not providing this feature, and I would like to know what it is.
