IS there a way to find out in console what model is causing the 'Changes you made may be saved' popu

In the browsers developer tools console you can use a “For.Each” loop to work through an array of model data and retrieve particular aspects of the model data into a nice list.

If you are working in a V1 page put this in the console:

skuid.$.each(skuid.model.map(),function(i,mod) {
  console.log(mod.id," ",mod.changes)
});

If you are  using the V2 page put this in the console: 
var mods = skuid.debug.models();
mods.forEach(function(mod){
 console.log(mod.id," ",mod.changes);
});

Note - this strategy can be used to return a list of any model property. Where is you error? What models have data? What models have conditions? Any model property can be listed this way.

Enjoy!
