I’ve been tinkering with this over the past few weeks and in many cases its working very nicely. I’ve figured out ways I can use the ‘any’ and ‘all’ rules to cover almost any situation which is great.
There’s one issue - some layer controls (checkboxes) should not be seen by the user. E.g. ‘n’ and ‘f’ on the example below. We set it up to accommodate that originally, with an array property called ‘control: true/false’. However, the evaluateRule function uses those checkboxes – so if “control: false”, the rules for that layer are ignored. Any ideas how I can get around this (so a layer can have its control:false but its rules still evaluate)?
