Facing the same issue ""oracle.jbo.JboException: JBO-29000: Unexpected exception caught: oracle.jbo.InvalidParamException, msg=JBO-25006: Invalid parameter value PosViewLinesVO for source passed to method ViewLinkImpl.setSource. Explanation: view def mismatch". "
Please help me to resolve this issue.
Please do this:
1. if you are not extending VOImpl and VORowImpl then do not generate these files for your custom VO instead let it use standard ones.
2. See if you have downloaded view link and all the related view objects when performing extension in JDeveloper.
basically you need to understand how view objects xml files are updated when using view links.
I believe JDeveloper could not updated required information in your VO.xml files and hence the error.
