Validation on a Repeating Grid of Checkboxes
Working in 7.2.1, we have a repeating grid with checkboxes where none are selected initially. We want to include a validation to require at least one of the checkboxes is checked before submission. Working from a previous example (https://pdn.pega.com/community/pega-product-support/question/how-do-validation-repeating-grid) we were unable to follow exactly where the when rule should be created and where the rule using it would be instantiated. Any clarifications (we are new to Pega) with more specificity would be greatly appreciated.

Hi,
We solved the problem, but it was not the most elegant Pega solution we could of done. We are just glad that it works as being beginners Pega developers :) At a very high level we did:
1) Created a an integer property flag to track if the checkboxes were clicked.
2) Created a data transforms that updated the flad property
3) Created a validate rule to check the value of the property flag.
4) Created a Flow action to perform the task if the flag was zero to prompt user to make at least one choice
5) Added a Flow that called the Flow action.

Hi,
A checkbox is associated with a TrueFalse property. If the checkbox is not checked, the value is false, otherwise is true.
A validate rule (called from FlowAction) needs to be written to check the values.
https://pdn.pega.com/community/pega-product-support/question/how-do-validation-repeating-grid
The above discussion mentioned several ways ("IsInPageList" or "countInPageListWhen") to check values.
You only need to check if there is one True value in the list for the checkbox property, then submission can continue.

At a high level, we understand those ways, but we are having difficulty with the specific implementation.
In that forum, it was instructed to create a "when" rule, then use that rule in the validation. We were unclear exactly how to set up that "when" rule, and the proper usage of said rule when setting up the validation. Any specifics on these points would be greatly appreciated.
