How would you refer to an entry in a page list property named LineItems?

To refer to an entry in a page list property called LineItems, the correct approach is to use the syntax that includes a dot prefix followed by the property name and an index identifier in parentheses. This indicates that you are accessing a specific entry within the list.

Using ".LineItems(#)" reflects the proper syntax for referencing a specific item in a page list. The dot prefix indicates that you are accessing a property of the current page, while the "#", representing the index, allows you to specify which entry you want to interact with in the LineItems list.

In Pega, the syntax is important for clarity in accessing and manipulating data. The inclusion of the index is crucial to denote which specific entry within the list you are referring to, allowing for appropriate data handling operations.

This precise notation distinguishes it from simply stating "LineItems(#)" which does not include the necessary context for the current page. Similarly, ".LineItems" without the index suggests reference to the entire list rather than a specific entry, and "Value.LineItems(#)" incorrectly introduces "Value," which does not pertain to the structure of accessing properties in this context.
