Hi,
In Pages and Classes , we can put page name as 'D_ABCList.pxResults' and Class should be Data page's Object type 'Data-ABC'. Then rule is saved. We can access first element by D_ABCList.pxResults(1).Code, if data page doesn't have any parameters.
Thanks.

Hi,
Try D_ABCList.pxResults(1).Code
Make sure to include the class of datapage in pages and classes tab of data transform.

Alternative:
You can copy the all results from datapage into a pagelist property using a datatransform and get the first result from that pagelist.
eg: TestPageList(1).code
This should work.
Thanks.

Hi, thanks for reply, I have tried "D_ABCList.pxResults(1).Code" and put "D_ABCList: Data-ABC" in the Page & Classes tab
Then It returns "Source—Property @baseclass.Code is undefined." Error.
Do you have any clue why it happen?

Hello ,
You can access the page list with pxresults and then access the property something like this below
pagelist.pxResults(count).code .
Thanks,

What if the Data Page does have parameters?
jsp tags like <pega:reference/> or <pega:withPage/>, etc., don't seem to like the D_DataPageName[ParameterName:"value"] syntax ... how can one access parameter-ized data pages from jsp tags?
