Hi, Isomorphic,
We've encountered a bug in SmartClient core then servers responds with fetch operation then totalRows is more than 126000 records. Looks like Chrome will throw call stack exception then `addCacheData` method tries to call `addListAt` on this.localData array.
The problem is that localData.length is set to 126000 in `setFullLength` and problems begins at: addListAt:
I cannot find a way how to fast fix that, maybe do you have some tips how can we workaround this? Some disable cache option or something?
Also tested on latest SmartClient 10.x LGPL 2017-02-18

Code:
var tail = this.splice(pos, this.length - pos); // tail array will become very very large, 126000 items.. // add back the tail this.push.apply(this, tail); // <-- here we're getting call stack exceeded looks like Chrome can't call a function with 126000 arguments :)
