Hi Arafath,

I have been trying to build a representative test case here for testing with ; but I got stuck.

I have two ideas (not solutions - more diagnostics I'm afraid):

1. Can you provide more screenshots showing your data model setup in more detail please; it might just be me, but I can't work out whether you have used 'Page Lists' or 'Page Groups' here....

2. Can you make the data 'fit' your Pega Data Model in another way (again, not a solution - a diagnostic) - can you build a Data Transform which fills your model with your example data; and show the XML of the result.

Then we'll have your input (the JSON) and the expected output (the filled-in data model).

So I'm struggling to get my head around how to represent this data ; but I'll post what I have been trying in case it helps shed some light (mainly on what I'm doing wrong here I think... :-\ )

Cheers

John

Just to show I have thought (badly, but I did try :-) ) about this:

So I have built a PRPC Activity - that loads some JSON (from a Rule-File-Text for convenience)

And created a data model (which is almost certaintly wrongly thought-out on my part) like this:

Where I have 'Tuple' that contains a single property 'Values' - which itself a Page-List of type Values...

(again, I think this is probably all wrongly thought-out).

If my input JSON is this:

{
     "answer": "yes",
 "additionalInfo": [ "a","b" ]
}

i.e. A top-level Javascript Object / Dictionary which contains a scalar 'answer' keypair and a simple list (i.e. its members are all scalar) 'additionalinfo' keypair'.

This maps like this:

<pagedata>
<answer>yes</answer>
<pzStatus>false</pzStatus>
<additionalInfo REPEATINGTYPE="PropertyList">
<rowdata REPEATINGINDEX="1">a</rowdata>
<rowdata REPEATINGINDEX="2">b</rowdata>
</additionalInfo>
</pagedata>

But if change it to this (i.e. introduce a complex (1 item list) item within the outer list):

{
     "answer": "yes",
	"additionalInfo": [ ["a"],"b" ]
}

It doesn't map: I get an exception in the logs:

Caused by: com.pega.pegarules.pub.clipboard.InvalidParameterException: ClipboardProperty value must have mode of String, Page, or Java Object.  Details: Invalid value for aValue passed to com.pega.pegarules.data.internal.clipboard.ClipboardPropertyImpl.addToList(boolean, int, Object, boolean)
