Error: Region could not be found in AK_REGIONS;

Question

we are doing one customization in which we are calling
pageContext.forwardImmediatelyToCurrentPage(params, true,
OAWebBeanConstants.ADD_BREAD_CRUMB_NO); from process form request
and in process request we are checking the parameter passes from process form request and performing some action.
Till then it works fine.
But when i try to save it it gives me error
oracle.apps.fnd.framework.OAException: Region could not be found in AK_REGIONS; RegionCode: RegionApplicationId: -1
One reason i found it that tthis error comes by incorrect splicing of the destination url.
As after calling the pageContext.forwardImmediatelyToCurrentPage.. The Destination URL changes and the parameter comes before the page file path.
The destination URL is like:
http://usmlrh212.arrow.com:8001/OA_HTML/OA.jsp?*unityDisableComm=enableCommTrans&*page=/oracle/apps/po/document/order/webui/OrderPG&poHeaderId=28883&poMode=update&_ti=1884540900&retainAM=Y&addBreadCrumb=N&oapc=37&oas=_5_96RCwgs5afXKfJWzrrw..
Any suggestion to overcome thiss issue?

Answer 1

What is the destination URL, if it is a function then provide the web_html_call for it. If it is of type OA.jsp?akRegionCode=.... then you need to check if the FND : Migrated To JRAD for this application is set to Yes. If it is set to yes then is this a seeded Oracle function or destination ? If no then you should not use this syntax, you should be rather using OA.jsp?page=... format.
Also always provide #detail0 part of the exception.
