Hello,
I haven't seen an ACEView/ACEViewDelegate API to determine if the content of the view are not conforming to the specified language. For example, if I set the ACEView mode to be ACEModeJSON and I edit the contents removing a comma, a red "X" appears in the gutter (awesome!). I'd love to programmatically figure out if the view is showing one or more "X"'s so that I can redraw the rest of the UI accordingly. Did I overlook this API somewhere? Thanks!
