since extjs5 Store.snapshot does not exist anymore, we didnt remove filtered records this lead to the fact, that the 'message' record did not get removed and a "no subscription file" message was shown directly after uploading a key to get also the filtered records in the store we use store.getData().getSource() Signed-off-by: Dominik Csapak <d.csapak@proxmox.com>

/*

|
* The DiffStore is a in-memory store acting as proxy between a real store
|
|
* instance and a component.
|
|
* Its purpose is to redisplay the component *only* if the data has been changed
|
|
* inside the real store, to avoid the annoying visual flickering of using
|
|
* the real store directly.
|
|
*
|
|
* Implementation:
|
|
* The DiffStore monitors via mon() the 'load' events sent by the real store.
|
|
* On each 'load' event, the DiffStore compares its own content with the target
|
|
* store (call to cond_add_item()) and then fires a 'refresh' event.
|
|
* The 'refresh' event will automatically trigger a view refresh on the component
|
|
* who binds to this store.
|
|
*/
|
|
|
|
/* Config properties:
|
|
* rstore: the realstore which will autorefresh its content from the API
|
|
* Only works if rstore has a model and use 'idProperty'
|
|
* sortAfterUpdate: sort the diffstore before rendering the view
