Need help in displaying multiple attachments in a OAF Page

Question

Hi,
I need to display attachemts of requisition line in a OAF Page(Notification Detials Page)and the attachments can be more than one.My custom VO returns it as a single string like url1, url2.. etc.
I need to show them as seperate links.
I tried using the Item Style as LINK.But it is not working.It is prefixing the server url before the View Attribute and creating a single link.
Any help in this regard will be appreciated.Thanks in advance.

Hi skeerthi,
If you are using the core attachments table (FND_ATTACHED_DOCUMENTS and the like), you can have a look on the Developer's Guide on chapter 4: Implementing Specific UI Features, section "Attachments", there is a seeded region available for displaying multiple attachments.
If you are not, then i'd recommend refactoring :D... Just kidding, it would be nice to use the core feature, but if the table is custom, and the links are stored separated by commas, you will have to write controller code to implement that. That can be done by:
1) Creating an Application module method that uses StringTokenizer to tokenize the attribute String (use getViewObject().getCurrentRow().getAttribute() to get the comma-separated value) and return that to the controller
2) In the controller, receive the StringTokenizer and for each token, use the api createWebBean() to create an OALinkBean and add it to a layout region using addIndexedChild() api.
This way you will dinamically create a Link for each attachment. If your layout region is, for example, tableLayout, you can create a rowLayout for each token, then create a Link, add the link to the row layout and finally add it to the tableLayout. By doing so, you will create a table-style attachment region.
Hope it Helps
