Asynchronous Data Page not working 7.1.9
Hello, I'm trying to load Datapage Asynchronously. On tab click calling activity which will do load Datapage method at step 2 and show harness will be executed at step 16. In harness have section which contains a layout inside thus layout, section include and the context page is data page and the layout is configured as defer contents. But until unless the datapage execution completes then only im able to perform button clicks and remaining things. Thanks...!

Swarenendu, it seems to be working fine now. Please see my closing comments on the SR
"I just discovered the problem. The section had a visibility condition dependent on the Data Page itself. So that was getting fired & causing the DP to load synchronously.
I had to tweak the section & the when conditions so that the when rule doesn’t fire before the section is referred. It seems to be working fine now."
Please check in the tracer if your DP is loading asynchronously or not by checking ADP. Also see the word Doc I am attaching for complete details on how to achieve non blocking UI in Pega 7

Hi,
Please check this pdn online help:
https://community.pega.com/sites/default/files/help_v719/procomhelpmain.htm
Connect-Wait is used to wait for pages loaded by Load-DataPage.
The pool id parameter to Connect-Wait method is a token used to group Data Pages loaded in the background by Load-DataPage method. When this parameter is set, the Connect-Wait method will wait for all the data pages that are loaded with the same pool id.
So, in your use case, you can add step 3 as "Connect-Wait" and then the rest of steps of your activity.

Yes Step 3 is connect wait.
The Data Page Source activity having step 1 as java which will do Thread Sleep for 30 seconds. I have added this step to test Asynchronous Data Page Functionality.

Hi Srinivas,
Your Step 3, "Connect-Wait', has an empty WaitSeconds.
Can you put a value there?

Hello Susan,
Kept seconds still not working..
My requirement is to load Data Pages Asynchronously which will avoid blocking UI.
This is what I'm trying to do.
we have 6 sections in 6 layouts (Defer Load) for each of them context page is using data page and these data pages are configured loading asynchronously using Load-Data Page.
I'm only able to perform UI actions after all of them are loaded.
Is non blocking UI concept not existing anymore in Pega 7 ?
https://docs-previous.pega.com/how-configure-non-blocking-ui-using-asynchronous-declare-pages
One more question is if we are loading Data Page asynchronously then if I use Connect-Wait then this process finally making the Data Page as Synchronous only right.Let me know if my assumption is wrong.
Thanks..!

Hi,
In the tracer, if you don't see the Data Page to be loaded, please try to do a data page cleanup - do a "flush all" on your D_Test_Async data page.
Thanks,
Susan
