Prefill service using FDM to fill the table

[ShaileshBassi]

Trying to implement the use case mentioned in the document i.e. https://experienceleague.adobe.com/docs/experience-manager-learn/forms/prefill-fdm-db/introduction.h...

But I am not able to get the table prepopulated with the data.

I have followed the similar steps mentioned in the document. Below are the screenshots

When doing the "Test Model Object", it is showing me the result as present in the MySQL server

can anyone please help with any pointers, what could be missing over here to get the prefill of the form and its beneficiary table.

Thanks

@ShaileshBassi Can you check logs and error coming in

[Lavanya_Pejjayi]

Hello  shaileshbassi,

I suggest you check the logs if any error is coming up or

you can also check at form properties whether it is pointing to the right FDM  model schema or not? 

Thanks,

There is only a warning message in the logs i.e.

As already mentioned check error.log for errors.

It's a little tricky tutorial to follow.

Are you seeing the following line in your stdout.log

Adobe !!!There is a empID parameter in the request 207

[ShaileshBassi]

@MorisMonk No, I am not getting this in the stdout.log file.

Thanks

[MorisMonk · Accepted solution]

Then your form is not using the custom template (FDMDemo).
See https://experienceleague.adobe.com/docs/experience-manager-learn/forms/prefill-fdm-db/get-request-pa...

I am assuming you did not use the sample form, link on https://experienceleague.adobe.com/docs/experience-manager-learn/forms/prefill-fdm-db/create-adaptiv...

If you did, then check following:

- Form properties, Form Model is set to that which you created.

- Adaptive form container, Prefill Service is set to "Form Data Model Prefill service".

- All form fields are bound properly.

[ShaileshBassi]

@MorisMonk I have checked the above 3 points stated by you:

Point 1:

Point 2:

Point 3:

But still it is not working. Is there anything else which should be checked.

Thanks

[MorisMonk]

Did you complete the steps on this page ?
https://experienceleague.adobe.com/docs/experience-manager-learn/forms/prefill-fdm-db/get-request-pa...

Your form needs to be using this template (FDMDemo).

Make sure you uncomment the following lines as mentioned on that page.

if(request.getParameter("empID")!=null) {
      System.out.println("Adobe !!!There is a empID parameter in the request "+request.getParameter("empID"));
      java.util.Map paraMap = new java.util.HashMap();
      paraMap.put("empID",request.getParameter("empID"));
      slingRequest.setAttribute("paramMap",paraMap);
    }

You can see this is where that log line is output (you are not seeing at the moment), as well as what is required to perform the get service on your FDM. All explained well enough on that page.

You can got to CRXDE Lite and check you current form.

Example, /content/forms/af/training/af-with-fdm-employee-association-beneficiary/jcr:content
Property cq:template should be /conf/global/settings/wcm/templates/fdmdemo
Property sling:resourceType should be fdmdemo/component/page/fdmdemo

[ShaileshBassi]

Thanks @MorisMonk it worked. 

I have one doubt, earlier I was using the sling:resourceType fd/af/components/page2/aftemplatedpage

and now using the fdmdemo/component/page/fdmdemo.

So the nutshell is if we want to use the request parameter we need to set that in the "slingRequest" attribute as we are doing it in "/apps/fdmdemo/component/page/fdmdemo/fdmrequest.jsp". Is my understanding correct?

So, if I want to enter the text in the input field and based on that if I need to get the details, what should be done in that case?

Thanks
