Performing multiple data store filter requests

[Tim]

Hi,

We have a server side filtering component to our data store. When we issue multiple requests before the server can respond:

dataStore.filter({ user_id: 1 });

dataStore.filter({ user_id: 2 });

The "user_id = 1" request may end up coming after the second request, which means the displayed data is not what the user requested.

Is there a way that this can be fixed? It seems like we can only listen to onChange events in the dataSource, which unfortunately don't tell us which request this response data is for. Thanks!

Hello,

 You need to wait for the first request to complete before issuing a second one. Could you please let us know what exactly are you trying to achieve? Perhaps there are better ways to accomplish your task.

All the best,

Hi,

We have navigation links on the left side that perform server-side filtering of user data (see screenshot). When a user clicks the link on the left, it cause the middle section to load new data.

Is there a better way this should be performed? Thanks!

Hi,

 You can try disabling all filtering links until the response from the datasource is received (the change event is raised).
