Form Paramter in OA Framework

by

In Oracle Apps Framework the formParameter item style provides the functionality to act as a placeholder for submission parameters. Suppose you want a user to fill his credit card details and then you want to call a payment gateway by passing his credit card information, then you will use the formParameter bean to hold the values of the credit card filled by the user in the OAF page.

Oracle Application Framework also provides the formValue bean for holding the values, but there are differences between formParameter and formValue beans of OAF, these are listed below.

1. formParameter won’t support a “value” attribute. Instead, the value is set only at form submission time.
2. A formParameter with a particular name can be added N number of times to a form without ill effects; only one instance will appear. This is noticeably different from the formValue, where reuse will cause the same value to appear multiple times in the form submission.

Form Value in OA Framework

by

In Oracle Apps Framework the formValue bean is used to add value that will be submitted with a form, but the key point to mention is that value is not displayed to the user.

To make the formValue bean get a value the formValue’s ViewName and ViewAttribute has to be mapped to a View Object and as soon as that View Object is executed the formValue get’s the value of the mapped attribute.

Image Item in OA Framework

by

Suppose you want to show an image on to an Oracle Application Framework page then you have to use the Oracle Apps Framework provided Image bean. This bean has to be mapped to an image so that the image can be displayed to once the OAF page is rendered.

For example when we see an update column in a table, that column uses image bean to display the image of update icon.

Link Item In OA Framework

by

The Oracle Application Framework provides the Link bean so that you can redirect the control to any other page once the Link bean has been clicked. The link bean item style creates an HTML link tag which can then be redirected to some other page as required.

To open a new browser on the click of the link bean from an OAF page you just need to make the target property of the link bean to _blank.

Message Choice Bean in OA Framework

by

In order to make a drop down box in any Oracle Application Framework page the messageChoice bean is used. The messageChoice bean gives the user the functionality to select a value from the drop down list in an Oracle Apps page. People often get confused between the MessageChoice and the List Of Values (LOV), whereas there are huge differences between both.

Value of the dropdown list of MessageChoice bean comes from the BC4J object.
