Dgrid getChilldren asyncronous call to server


We are trying to implement a dgrid that supports lazy loading (asynchronous) of children nodes (when a parent is expanded to call a server method to bring its childrens).
We tried overriding the getChildren method of dstore/Tree but this seems to be synchronous.
Is there a workaround?


This is one of those problems that has been difficult to get right generally, but is possible to override yourself should you know your specific use case. https://github.com/SitePen/dgrid/issues/115 was the original issue and there are other issues linked to it that discuss some of the pros and cons. It may be worth opening a new issue to consider revisiting this.
