Grouping fields from VBO selected entities

Problem/Motivation

ECA rocks! I've effectively replaced all my rules and many of my sub-modules. But with the ECA VBO action, I am hitting some limits of what I can do by myself and time to ask for some help!

I am unclear on how to use ECA VBO to collect values of a field from selected entities (nodes) and aggregate them into a single field. For example, collect the {nid} values from several VBO-selected "Data Nodes" and combine the results into a single field.

Using ECA VBO One-by-One, it's easy to set a token using [entity:nid:value], but when displaying the results, each collected field is in its own distinct field. Perhaps there's a way to combine these results into a single field?

Using ECA VBO Multiple-at-Once, I am able to see results using [event:queue:ids] and multiple results appear to be in same field, but they include some unwanted characters such as dashes and single quotes. Is there a way to access other fields from these nodes?

Steps to reproduce

Create VBO using One-by-One that allows user to select multiple nodes of same content type and set the nid values into a token, then display that token as message to user. The result is each collected value is displayed as a separate message. See screenshot 1.

To test the VBO Multiple-at_once, create a VBO that allows user to select multiple nodes of same content type and set a token for the node ids using [event:queue:ids]. The result is a single message with the node ids. See screenshot 2.

Proposed resolution

The following documentation would help:

• More description about use of ECA VBO Multiple-at-Once
• More description about use of ECA Loops
• Example of ECA VBO One-by-One processing results
• Example of ECA VBO Multiple-at-Once processing results

Thanks!
