Hi @tushaar_srivastava,

Workflow models rendering logic

In Classic UI is /libs/cq/workflow/components/console/models/options.json.jsp

In Touch UI is /libs/cq/workflow/admin/console/components/datasource/modelsdatasource/modelsdatasource.jsp

Both retrieves models from WorkflowSession but former from com.day.cq.workflow.* API and latter using com.adobe.granite.workflow.*

Given that problem is in Touch UI alone, per the logic you should see a log message in error.log - "Error while retrieving workflow models." (Screenshot below)

Also you have mentioned that you have tried creating many new models, can you check where it got created. Is it under /var or /etc (if its fresh 6.5 instance, it should be in /var)

Hi Team, I tried to clear error.log and checked, I have deleted one Workflow Model from CRX that was under /var and /conf folder and because of this manually deleting the model, affected on the WF Model screen as per attached above. when I checked log and created the same model in Local and uploaded it into the local where this error was coming, then it got resolved, still wondering by deleting the WF Model from /var & /conf from CRX how this affected?

My first question is after deleting how did u create this model? Was it via code deployment or via workflow console?

Either way, when you create the model you will definitely see it in /conf.

You just have to make sure it exists in /var also.

If not, just open http://localhost:4502/cf#/conf/settings/workflow/models/my-model.html

manually and save it. This will create a /var node then you will be able to see the model.

My first question is after deleting how did u create this model? by going through WF console. but once I created a WF Model though WF console and can see the node created under /var and /conf and if manually we delete those WF through CRX in that case this WF Model console is blank. and when I again created the WF which I deleted in different Local and uploaded into the local where we were seeing issue, then it worked.

Issue is now resolved for me....
There was one workflow model at my side wherein the design time path was not found properly under /conf which was creating the issue.
