Description
When several updates are available for a particular element, ICEfaces will coalesce these (based on the element ID) into the latest update. This is a performance optimization that avoids overwhelming clients that are unable to retrieve updates as quickly as the server can generate them. In some cases, however (such as for a component that records changes from the last time it was rendered) this update coalescing should not be performed.
Then intent of this JIRA is to provide a configuration parameter for turning off update coalescing. A more fully-featured implementation might allow coalescing to be configured selectively for different components or regions of the page.

Set coalesceUpdates to false to turn off the update coalescing optimization. This is useful for custom components that make non-idempotent changes to the DOM (changes that depend on previous renders, not just the current state of the component).
