What is the syntax to get the SUM of a pagelist and pagegroup property using JSP in a Paragraph rule?
If I have a pagelist called SomePageList with a property called SomeInteger on it. How do I get the SUM of SomeInteger and show it in a Paragraph rule using JSP tags?
I want to output something like:
<%= <pega:reference name="@sum(SomePageList.SomeInteger)"></pega:reference> %>

Hi,
I am not sure if there is such API / method that can get the SUM of SomeInteger in SomePageList.
But why can't you write an activity to do so?
Just loop on SomePageList - For Each Embedded Page
get each SomePageList(<CURRENT>).SomeInteger and then add them together to get the SUM.
Once you get the SUM, you can display it as a read-only string/text in paragraph rule.
Paragraph rules can be referenced in other stream rules through the <pega:include > JSP tag.
For example, a section refers to a paragraph (via Parameter name) : you can use
<pega:include name="Param.ParagraphName" type="Rule-HTML-Paragraph"/>
