This post describes changes made in Dynamic Forms For SharePoint (DFFS): http://spjsblog.com/dffs/
I have updated DFFS and introduced some new triggers and improved the functionality related to linked rules.
You can now use a custom function as a rule trigger, and you can also set up rules that can only be triggered by other rules (trough “Run these functions / trigger these rules”), or by a custom function.
You can manually trigger all rules from a custom function like this:
Supply the rule identifiers as a comma separated array. Please note that the rule will be executed as if the trigger returned true.
Rules with lower index than the current rule, and custom fuctions will be evaluated. Reorder rules if necessary.
The “last run status” of the rules will be checked, and custom functions will be reevaluated.
Checking a custom function
To check the result of a custom function, use the name of the function without parentheses. You can combine a custom function with indexes or friendly name of other rules.
Checking multiple rules
Separate indexes or friendly name with comma to use [and]. Separate indexes or friendly name with pipe to use [or].
In this example, Rule1 and Rule2 must be true, and Rule3 or Rule4 must also be true for the overall result to return true.
