Hello ,
Thx for the reply. I have found a solution in the meantime. I execute my
query in the render response phase. Then my model values are properly
updated and then I have the filter values ready when I want to execute the
query.
I use saveState for saving the state of the Datatable.
The way you did it works for one filter parameter but if you have many
filter criteria then the code will become cumbersome.
