getBindings() not found in the bean support page

Hello

I want to call a method on AM during the click on the button to the user interface.

To do this, I exposed the AM method through the client interface.
Add code to call this method of support following page bean:
--------------------------------------
BindingContainer links = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding ("updateAvailableQty");

If you want to put values in method parameters:
operationBinding.getParamsMap () .put ("orderedQuantity",
New Integer (orderQty));

Object result = operationBinding.execute ();
If (! operationBinding.getErrors () .isEmpty ()) {}
System.out.println ("error getting the operationbinding!");
---------------------------------------------------

getBindings() method is as follows:
----------------------------------------------------
public BindingContainer {} getBindings()
If (this.bindings == null) {}
FacesContext fc = FacesContext.getCurrentInstance ();
This.Bindings =
(BindingContainer) fc.getApplication () .evaluateExpressionGet (CF,
"#{bindings}."
BindingContainer.class);
}
Return this.bindings;
}
----------------------------------------------------


It displays error complition "Error (151,22): bindings of variables found in the view.backing.OrderPage class.

Please advise in this regard.
Thank you

You must declare a local variabel links in your beans to make the code work:

BindingContainer bindings = null;

public BindingContainer getBindings() {
if (this.bindings == null) {
FacesContext fc = FacesContext.getCurrentInstance();
this.bindings =
(BindingContainer)fc.getApplication().evaluateExpressionGet(fc,
"#{bindings}",
BindingContainer.class);
}
return this.bindings;
}

// your method  here

  • error AVCFPlayerSetclientEnforcedExternalProjectionMethod is not found in the AVFoundationCF.dll dynamic link library

    I tried to update my iTunes this weekend.  Now, I can't open it I get this error: AVCFPlayerSetclientEnforcedExternalProjectionMethod is not found in the AVFoundationCF.dll dynamic link library is on a Windows 7 computer.  I tried to re - install outside of iTunes and repair.  But no luck.  Should I uninstall iTune and then re-install?  Help.

    These errors can usually be fixed by removing the offending dll, then fix the component it is programs and features Control Panel. AVFoundationCF.dll belongs to Apple Application Support and are normally in

    • C:\Program Files\Fichiers Files\Apple\Apple Application Support or
    • C:\Program Files (x 86) \Common Files\Apple\Apple Application Support

    where the name of the Program Files folder may vary depending on the region.

    For general advice, see troubleshooting problems with iTunes for Windows updates.

    The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach. Review other cases and a list of documents to support further down the page, in which case one of them applies.

    More information area has direct links with the current and recent if you have problems to download, must revert to a previous version or want to try the version of iTunes for Windows (64-bit-for old video cards) as a workaround for the problems of performance or compatibility with third-party software.

    Your library must be affected by these measures, but it is also related to backup and recovery advice if necessary.

    I would ask about the error I recently.
    I don't know what's wrong with my code, but I '_enableThemes_ method not found in the class oracle.lbs.mapclient.MapViewer' when I tried to apply a theme to my card using the API of Java Bean.

    Another method does not recognize mapviewer is '_setAllThemesEnabled_ '.

    I don't know how to apply some themes I did for my card despite the use of the method.
    I have already imported oracle.lbs.mapclient.MapViewer.

    Hello
    Make sure that you type the correct setting. EnableThemes method requires an array of strings. Try the following:

    mv.enableThemes (new String() {"THEMENAME"});

    I want to prevent access to the ' topic: support ' page. How to accomplish this task?

    You must create the userContent.css file and possibly the record chrome as well if they do not yet exist.
    Note that the names are case-sensitive.

    • Create the folder chrome (lowercase) in the .default < xxxxxxxx > profile folder if the folder does not exist
    • Use a text editor like Notepad to create a file userContent.css (new) in the folder chrome (file name is case sensitive)
    • Paste the code into the userContent.css file in the Editor window
    • Make sure that you select "All files" and not "text files" when you save the file via "save file as" in the text editor as userContent.css.
      Otherwise, Windows can add a hidden .txt file extension and you end up with one does not not userContent.css.txt file
