 Build a List Screen Exercise/ Data is not showing

I am doing the Build a List Screen Exercise I followed all steps but no data is showing, and no error is generated. I did follow all steps:
My Table Source as the GetProject.List set

The Table was populated with the Project Entity.
My Expression in name has the Valuer set as GetProjects.List.Current.Project.Name
I went ot the Table and checked the Entity Project: View od Edit Data. It does bring the columns( Id, Name, Description, DueDate). No rows on it, "! No records to show" 


I am having the same issue with all projects where They do not show the row, records, of the table. 
I am assuming that the Lessons material has all sorted as in the example doesnt ask to populate and expect the result already.
Should I populate it by my-self?

Hi @Gleisson Santos Silva,

Is there any data in the Project Entity and if No then you need to add data.

To ensure better comprehension, it would be helpful if you could share the OML file.

@Neha Rathore, I can add the information, but it should be automatically in the database. Should be in the lessons material.

Yes I think you need to bootstrap.

There must be some excel data which you can bootstrap in your project.

May I know which lesson material you are referring to?

Please see the updated OML.

I just deleted the entity and added back again by dragging and dropping and it is working fine.

Hope this helps

Thanks

Hi Gleisson,

It seems that the process to populate the Entity in the database with records was not completed for some reason, which is why you're seeing an empty Table.

From what I see in the exercise, you're not required to populate the data manually, but rather, as you mentioned, just expect it to happen automatically. The way that happens is that the module will run a Timer to bootstrap the data, so you have a couple options:

Option a) Just republish the module by adding any changes and wait a couple minutes. The timer is set to run when-published so it should bootstrap the data.

Option b) Go to Service Center by clicking the Gear Icon at the top of the window in Service Studio, and re-run the Bootstrap timer by going to the "Timers" tab in the module detail, selecting the timer and clicking on "Run Now".

Option c) Delete the application and reinstall it in Service Studio by opening the OAP file from the Lesson materials. This would require you to re-do the exercise but hopefully that's not too big of an effort.

If none of these options work, there might be some other issue that is preventing the Timer from being run. For that case I would recommend going into Service Center and checking the Error logs to see if give you additional information.

Let me know if this helps.

Francisco, thanks!!
I did all suggestions(a,b and c) and step but no success. My "timer logs" is empty!

If the Timer isn't running even after all these attempts it might be a sign of a different type of issue, do you see anything in your Errors Log in Service Center (Monitoring -> Errors)? If not, try also checking this thread for reference: Timers not running in personal environment | OutSystems - you might need to open a support case with OutSystems in order to get this solved.

Hi Gleisson,

I have downloaded your OML and i can see the list of projects being populated in the table. 

When you bootstrap data from excel, normally it takes time to show that data in table.

There is some problem with bootstrap. My suggestion would be once you do bootstrap, open any other table for instance "User" entity and then open the entity for which you did bootstrap. I have faced the same issue before.  If you are able to see data in the entity your list will populate that on screen. 


Thanks,

Neha

Hi everyone!


Thanks for help!


The issue is solved, but I really don't know how. I went back to do the first Data modelling exercise and analyse if I did anything was wrong, but I was doing everything right. I also check my Environment Health page in Service Center, all logs and nothing wrong was showing.
After doing some test and nothing solve I decide to open a issue in the Support and when I check again my project the data was showing... All data from all projects which was not showing before is now available.
So, I don't know what was the issue neither how to solve it but is working now.

Hi Gleisson,
(I m just guessing here )
With all above events, It is possible that there was a glitch in your personal cloud environment and that when you went for health check pages the cloud recovered the data storage part for your account.

Someone who knows in and out of Outsystems ( maybe from core team ) would be able to pin point why this happened. 

Even though your issue is resolved i suggest you open a support case because it will come to outsystem team's notice. 

Thanks
