[tushaar_srivastava]

Hi @tushaar_srivastava,

Do you see any error in AEM error.log when you hit the workflow model screen, please share the logs?

Thanks!!

[tushaar_srivastava]

I tried to refactor(beautify) this log but seems it is not accepting in comments. Could you please check this one

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)

[tushaar_srivastava]

it is under /var

[tushaar_srivastava]

I can see in my logs

*ERROR* [sling-threadpool-ed45eed2-832a-447b-b5d0-fe409fea7198-(com.day.cq.wcm.workflow.impl.wcmworkflowserviceimpl)-6] com.day.cq.wcm.workflow.impl.WorkflowAutoAssignAllocator Unable to read all workflow auto assign rules: /etc/workflow/wcm/templates

Hi @tushaar_srivastava,

Save a copy of existing error.log file -> Clear the contents of existing log entries -> access Workflow models console in Touch UI once again and observe the logs. 

Also can you confirm

• there is no workflow models in /etc. All workflow models resides in /var only
• If it is a fresh install or in-place upgraded instance

[tushaar_srivastava]

Hi @Vijayalakshmi_S 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?

[Vijayalakshmi_S]

Hi @tushaar_srivastava,

You mean to say all OOB models and any custom models are in /etc and deleting things from /var and /conf help reflect the same in Models console?

Sorry, I couldn't follow the steps you have tried per your last comment.

[tushaar_srivastava]

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.

[Vijayalakshmi_S]

Hi @tushaar_srivastava,

Can you let know below details to narrow down the cause further.

• If your 6.5 instance is fresh install or in-place upgraded instance. 
• Was there any migration activity related to workflows
• At present where the OOB workflows residing in your instance? Is it in /etc or /conf and /var
• Background on from when it was not working.

[knitshweta]

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.

Hello All,

I am also facing the same issue that not able to see any workflow model under touch UI. It is working in Classic UI.

http://localhost:4512/libs/cq/workflow/admin/console/content/models.html

Getting below error in the log:

Any ideas how to get away with the issue

[abhiyash_agrawa]

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.
