Getting error: Unable to load data page. Please help.
Hi, I have a query related to data page. I have a section where I am entering username and on click of a button, the account details related to that username will be displayed in another section. The account details are there in D_AccountDetails data page. I have my data transform in the pre-processing of the section where the details will be displayed.
When I am entering Username in the first section and clicking on the button, the second section is getting displayed without any values and I am getting the following error:
-
Account Page:
Unable to load data page D_AccountDetails. Required parameters : Username. cannot be blank
Please help me regarding this.

Hi @SohamM95, The username is showing as null when I am running the tracer.
I have used a DT where I have set the target as a Page property and the source as "D_AccountDetails[Username:pyWorkPage.AccountPage.Username].Username".
Please let me know if this is correct and help me with the correct approach.

The configuration is correct, though its not recommended to use pyWorkPage in param. Before the data page is executing, check the value of pyWorkPage.AccountPage.Username in the tracer.

@DebadritaD2693 Please check the clipboard that entered username name value there or not. and also check how you are passing the parameter to the data page.Exp:D_AccountDetails[Username:.username]

Hi @Nadimuthu T, the username is not getting populated in clipboard.
In the data transform I have set the Target as a Page type property .AccountPage and the source as" D_AccountDetails[Username:pyWorkPage.AccountPage.Username].Username".
I have also mentioned the data page name in Pages and Classes. But it is not working. Please let me know if the syntax I am using in the DT is correct or not.

Your configuration in the dt was correct, pls check the first section which property you are capturing the username and use the same property in the dpage parameter. Check the tracer event when the property value cleared.
