OAF attachment to be updated / deleted by creator only

Have you ever got a requirement in EBS FND attachments where in multiple users can add an attachment of the same category but only the person who has created it can delete or update it.

I achieved it recently in OAF by creating a custom DataBoundValueVIewObject class and associating it with update and delete icons of the attachment table. Since attachment table is a seeded region, I had to extend its controller to associate custom DataBoundValueVIewObject with update and delete icons.

  1. Create a custom DataBoundValueViewObject (xxOADataBoundValueViewObject ) class:

Oracle MAF Skinning

I tried two ways of doing skinning in MAF -
1. skin-addition -> skin-addition tag adds a new stylesheet to the existing skin
2. skin -> skin tag is used to define a new skin or to customize existing skin for particular OS or device.

Note: maf-config.xml file under Application Resources -> Dscriptors -> ADF META-INF contains the default skin family. That skin family will be applied to the application.

Oracle MAF - Using Panel Group Layout - wrap

In Oracle MAF one new option has been provided for the attribute "layout" of panelGroupLayout. It is very useful. I will give you a scenario: you want to create a contact us section where by you will want the text, followed by phone numbers(which should be clickable and should open phone dial on clicking) and email(clicking on which a write message of your default mail should open).

For such scenario you can use panel group layout with layout property set to wrap and inside it you can use output text and golinks to serve the purpose.

Oracle MAF - Issues, Tips and Tricks

Hi All,

I have built a mobile application using Mobile Application Framework released in July 2014.
In the mobile app I have done integration using REST services with JSON output. And the user will fill some forms and will send attachments from camera and library. The user can see history and I have used a pie chart as well for historical data.

Here is some of the issues, tricks which I learnt and I am sharing the same:




[11:29:47 AM] Checking state of Android Debug Bridge server...
[11:29:47 AM] Android Debug Bridge server already running.
[11:29:55 AM] Command-line executed: ["C:\Program Files\Android\android-sdk\platform-tools\adb", start-server]
[11:29:55 AM] ADB server didn't ACK
[11:29:55 AM] * failed to start daemon *
[11:29:55 AM] * daemon not running. starting it now on port 5037 *
[11:29:55 AM] Command-line execution failed (Return code: -1)
[11:29:55 AM] Deployment cancelled.

Go to platform-tools and kill adb server, it might be running because you would have done some debugging.
cd C:\Program Files\Android\android-sdk\platform-tools
adb kill-server

ADF Exception Handling - Taskflow, Controller, Model

Exception handling in ADF can be done at following three places:
a. Taskflow Exception Handler
b. Extending Controller level ExceptionHandler - for controller level exceptions
c. Extending DCErrorHandlerImpl- for model

  • Whenever there is an exception in model layer it is being handled by custom class extending DCErrorHandlerImpl.
  • Exception in ADF Controller can be handled by creating a custom class extending Controller level ExceptionHandler.
  • If an exception rethrown from above, it can be handled at TaskFlow level exception handler which can be a view activity, router or a method call.
One by one let`s discuss all of them:
