DuplicateRefException in Disconnected Application Instance after upgrading OIM to PS3

After upgrading OIM to PS3 from previous version (like PS1 or R2 base version), we observed that the disconnected application instance's form doesn't work properly. Issue may happen with create form  and modify form.


If the issue is in create form, then you will not be able to raise request of it. Submit of request will throw exceptions.
If issue is with modify form then request can be created but approvers/fulfillment users will not be able to see the form data from request.


we noticed that the issue occurred on those disconnected applications where there are some hidden field in request dataset.


The error looks like below.


oracle.mds.exception.MDSRuntimeException: MDS-00010: DuplicateRefException. In document /oracle/iam/ui/runtime/form/view/pages/[APP_NAME]CreateForm.jsff there are multiple elements with the same ID _xg_0


oracle.mds.exception.MDSRuntimeException: MDS-00010: DuplicateRefException. In document /oracle/iam/ui/runtime/form/view/pages/[APP_NAME]ModifyForm.jsff there are multiple elements with the same ID _xg_0


Solution


1. Export the whole MDS of identity self service.

$OIM_HOME/common/bin/wlst.sh
connect('${WL_USER}','${WL_PASSWORD}','${ADMIN_URL_T3}');
exportMetadata(application='oracle.iam.console.identity.self-service.ear', server='${OIM_INSTANCE_NAME}', toLocation='/tmp/mds');


2. Go to the location where the MDS is exported /tmp/mds.
3. Now move to /oracle/iam/ui/runtime/form/view/pages/mdssys/cust/site/site/
4. Here you can see the create form and modify form's jsff files for all the application instances.
5. Open the create or modify jsff file in editor mode. You can see there are 2 <af: panelFormLayout> tags, which are under same <mds: insert> tag

6. Edit this form and put each <af: panelFormLayout>  under a separate <mds: insert> tag, like below.

7. Save the form do the same for all other application forms.


You can also use the below Unix command to perform the bulk update on all the forms.


Create Forms


find /tmp/mds/oracle/iam/ui/runtime/form/view/pages/mdssys/cust/site/site/ -name *CreateForm.jsff.xml -exec \
 sed  --in-place -e '/<\/af:panelFormLayout>/,/<panelFormLayout id="_xg_0"/s/<\/af:panelFormLayout>/<\/af:panelFormLayout>\n<\/mds:insert>\n<mds:insert parent="sdh1" position="last">/' {} \;


Modify Forms


find /tmp/mds/oracle/iam/ui/runtime/form/view/pages/mdssys/cust/site/site/ -name *ModifyForm.jsff.xml -exec \
 sed  --in-place -e '/<\/af:panelFormLayout>/,/<panelFormLayout id="_xg_0"/s/<\/af:panelFormLayout>/<\/af:panelFormLayout>\n<\/mds:insert>\n<mds:insert parent="sdh1" position="last">/' {} \;


Note: Change the id="_xg_0" or "_xg_1" according to your error message.


8. Zip the entire MDS.


cd /tmp/mds
zip -r ../mds.zip . >/dev/null


9. Upload the mds zip to OIM MDS repository


$OIM_HOME/common/bin/wlst.sh
connect('${WL_USER}','${WL_PASSWORD}','${ADMIN_URL_T3}');
importMetadata(application='oracle.iam.console.identity.self-service.ear', server='$OIM_INSTANCE_NAME', fromLocation='/tmp/mds.zip');


10. Restart the OIM servers.
11. Check all the Disconnected Application Instance form from OIM identity console.
