We are in the process of upgrading our ADF-JHeadstart Application from 188.8.131.52 to 12c & we are facing issues:
Below are the steps followed for 184.108.40.206:
(eg. Generate adfc-config files, ADFC Page Definitions)
<Jul 2, 2018 2:11:35,610 PM BST> <Notice> <Stdout> <BEA-000000> <<oracle.adf.view> <RegionRenderer> <encodeAll> <The region component with id: pt:mr has detected a page fragment with multiple root components. Fragments with more than one root component may not display correctly in a region and may have a negative impact on performance. It is recommended that you restructure the page fragment to have a single root component.>>
The same application when upgrading to 12.1.3 using Jheadstart - jhs220.127.116.11.40-install is showing statement
<MULTIPLE_ROOTS_IN_FRAGMENT_REGION>> when any button is clicked.
Note : In both the applications, no manual changes are performed. af:commandButton are now converted to af:button in 12.* applications.
Please help us in resolving this issue.
