how a4j:support onblur validation optimisation?

[jimmy6]

I am using ajax support onblur to do validation for all the field. I want to optimise the performance now. I do not want the whole viewroot to be restored(the getter in bean will not be call).It is because i have a getter for datatable in that page.When each time the onblur on field. It will trigger the query to DB.How can i do that. How to avoid that?

wrap it to a4j:region with renderRegionOnly="true".. but in this case you may not reRender components outside region.

Also if you need only validation - use bypassUpdates on the support setted to true

How about limitToList property? I have the a a4j:region which contains all the inputText. It is for displaying ajax status. Does it mean i can not use the idea that mentioned by you? because region contains region.

limittolist property just denies refreshing ajaxRendered outputPanels

How to make sure it only one component to be restore in storeview phase?

[ilya_shaikovsky]

You may limit deconding and encodind of the region but not the concrece components.

What is the meaning of encode? Is it mean when i code in the following way, the 'B' and datatable will not be encode/restore in the rostore view phase? How to avoid the getter of 'B' and datatable being called in restore view phase when i onblur in 'A'.

<inputText id='B'...

<inputText id='A'.....
<support event='onblur'


<datatable ....

The code should be like this :

<inputText id='B'...

<region
<inputText id='A'.....
<support event='onblur'

<region

<datatable ....
