Description

I was testing the sample in Plunkr and printed the newValue and oldValue parameters. Their values have been reversed. "NewValue" is showing old value and vice versa. Below is documented function with 2 alert statements.

uiGridValidateService.setValidator('startWith', function(argument) { return function(newValue, oldValue, rowEntity, colDef) { if (!newValue) { return true; // We should not test for existence here } else { alert('newValue ' + newValue); alert('oldValue ' + oldValue); return newValue.startsWith(argument); } }; }, function(argument) { return 'You can only insert names starting with: "' + argument + '"'; }

);

Research direction
Investigate the uiGridValidateService implementation to locate where the validator function is invoked. Check the file likely named 'ui grid validate.js' to see how newValue and oldValue are passed to the callback. The issue indicates they are reversed, so the fix is to swap the order of the arguments in the invocation.
