filterMethod is called on every action on page

[abcd1]

Dear all

I have implemented filterMethod. but even if the i didnt type anything in the text boxes of filter ie, on every re render the filterMethod is been called. so my page is loading slowly.

i want to call the filterMethod only when someone types anything on the text Boxes.

Anyone know any solution
Thanks in advance
Cheers

filter method should be called every time on dataTable rendering in order to show current data carefully. filtering will be lost after request in other case.

thanks for the reply.
But it is calling the method for each row, ie no. of rows.
ie, if dataTable has 1000 rows it is calling the filterMethod 1000times even if the filter value is null.

can it be removed

[ilya_shaikovsky]

look.. your filter method could contains of any conditions.. So, we could not say that the condition for its calling is not null filterValue. So it should be called for every row.

thanks for the reply, now i understand.
but when i use filterBy the dataScroller attached with the dataTable is not rerendering. that is why i used filterMethod.
is it a bug.

reRender should work on the 3.2.2.CR1 version, dataScroller will be rerendered after using filterBy!
if it does not work, put the dataScroller inside a4j:outputPanel and reRender the outputPanel!

yes, add rerender="ds" to your dataTable component

Thanks for the help.
rerender is not there for dataTable in3.2.0

so i should update to 3.2.2 right?
