Fix an NPE caused by the previous fix to Grid's frozen columns (#11444)
* Fix an NPE caused by the previous fix to Grid's frozen columns (#10653)
If the user managed to get two frozen column count changes into a single server round-trip before the component had been attached, the previous fix #11346 lead to a null pointer exception since there was no diff state available.
This fix adds a null check before removing the frozen column count value from the diff state so that this will not happen.
Closes #10653
* add possibility to configure nested null behavior to Grid.Column
* added addColumn method that allows configuring the nested null handling behavior of the column
* added uitest for nested null value handling, implements #11137
Fix Grid's frozen columns not being set (#10653) (#11346)
In certain cases setting the frozen columns didn't produce the expected result in the client side widget state. This happened if the frozen columns value was set to be the same it was before removeAllColumns was called.
This fix removes the frozen column value from the diff state so that the value gets properly set in the client side.
Closes #10653
