cancelChanges is reverting even synced records to initial state

[Dirk]

Hi,

i created a datasource that's bound to a grid. When i edit a row of a grid and save the changes i do a sync. The update method is called and returned with an code of 200.

I then try to edit another row, but cancel this changes. In my cancel method of the datasource i call the dataSource.cancelChange() method.

But now all changes (even the synced ones) are reverted to the initial state ? Why ? What i am doing wrong in this scenario ?

 

Regards

Dirk

Hi,

sorry for the post - i found the reason why this was happening.

When i send the data to the update routine on the server  i did not send an id back to the client.

It would be nice if the documentation could specify, that a sync needs the updated data back to the client.

Hello Dirk,

We are glad that you have address the issue were facing. Indeed, the update method should return the updated records, this is mentioned in the documentation here.
