I have created an app, which using all ICEFaces components, to see what components are sending the form element as DOMUpdate.

The application has been designed so by default the component will not be rendered. To render the component the "render" check box need to be clicked, and the ICEFaces debug console should only show the element level update not the form level.

commandButton sends form level update

commandLink sends form level update

• dataPaginator sends form level update on render
• Sends element level update on navigation

menuBar component sends form level update if using actionListener

outputChart component sends form level update

panelCollapsible sends form level update

panelTabSet sends form level update

• selectInputDate sends form level update on render
• sends element level update on navigation

This bug is causing unacceptable performance in an application Neil Griffin is developing for a customer.

It is likely caused by the way that commandLink uses hidden fields (a different hidden field for each command link?). Since only one commandLink can be submitted at a time, one hidden field could be shared by multiple commandLinks. A single hidden field would not be added/removed due to changes in the page.

candidate fix for the selectInputDate:

• selectInputDate hidden fields placed inside root div for component
• FormRender.addHiddenField() checks for existence of hidden input before adding another hidden field to avoid duplicate commandLink hidden fields

I'm not seeing any form-level updates for the dataPaginator or the panelTabSet

Review attached

Branch 1.7 : revision 16470

Trunk : revision 16471

Changes made to the all renderes listed in the attached document. So none of the hidden field directly going to add to the "form" element anymore. That will prevent the form level update.

Verified successfully on revision# 16468

You forget about RowSelector.

Just add rowSelecotr to any table and you see that after selector click server response is very big and contain a whole form with table.
This is probably to main bug of icefaces - tested and exist on revision 17500

From the other hand in above RowSelector case after user select new row then should'nt be any server-client communication
until client not define in xhtml code selectionListener or partialSubmit="true"!

Create new JIRA for this bug?
