OAF Attachment : Make an attachment mandatory- iSupplier Portal

Currently we have developed a custom in the page controller Page: /oracle/apps/ap/invoice/request/webui/UnmatchedInvoicePG that validates that there is an attached document before continuing with the receipt load in ISupplier

With the release updated to 12.2.11 , changes are seen in the attachments section, and also the TEXT_ATTR property of the OAMessageAttachmentLinkBean class returns null.

Here is the custom code

OAMessageAttachmentLinkBean oamessageattachmentlinkbean = (OAMessageAttachmentLinkBean)webBean.findChildRecursive("Attachments");

String val = (String)oamessageattachmentlinkbean.getAttributeValue(pageContext.getRenderingContext(),TEXT_ATTR);

On this property we have developed the validation to control and make mandatory the entry of attachments on the receipt upload page in ISupplier.
