Hi,

i fill a grid step by step with many data from a database.

on load the grid is empty. an javascript fills the grid with a result of an ajax-request.

while he is loading the items every "tick" of inserting new items to the datasource, the grid lost the user-written text in the filters, so the user have to rewrite it.

you also lost the selecection of an row.

it looks like the grid will be rebuild in the DOM every time i add an item.

is there any mechanic to prevent this?

thats my grid:

and thas the javascript wich adds the lines:

    org.apache.struts2.json.JSONReader.buildInvalidInputException(JSONReader.java:155)

I did a debugging on the JSONInterceptor and found out that the json variable when trying to do the deserialize 
Object obj = JSONUtil.deserialize(request.getReader());
the json variable is an empty string.  Thus the above error.  


Second Scenario

Instead of calling a function to delete, i changed that to call an action. When doing this, the action
is called and my String models variable is set with the following values [{"lang":"de","text":"ProjectRoot-System","uuid":"c0437761-1c29-11e2-892e-0800200c9a66"}].

This seems sort of correct. Unfortunately with this case, the whole process does not go through the 
JSONInterceptor, so no deserialization is happening. 



So what is my goal:
To be able when pressing on delete to call the delete function and set the object with the values that are 
sent from kendo in order to continue with my own business logic process.  What could be wrong 
in my first scenario ? 

Please let me know if you need further information.

Regards

Stephan
