Constructor Arguments

conditions :: Array – required

a list of functions that take a viz object and return a string saying what went wrong.

For Example:

new Vamonos.Widget.Error({
    conditions: [
        function(viz){
            var s = viz.getVariable("s");
            var t = viz.getVariable("t");
            if (s.id === t.id) {
                return "Ford-Fulkerson says: s and t must be different!";
            }
        }
    ]
})
