Class AjaxResponse.AjaxResponseDelegate

java.lang.Object
  er.ajax.AjaxResponse.AjaxResponseDelegate

All Implemented Interfaces:

ERXAjaxApplication.ERXAjaxResponseDelegate

Enclosing class:

AjaxResponse

public static class AjaxResponse.AjaxResponseDelegate
extends java.lang.Object
implements ERXAjaxApplication.ERXAjaxResponseDelegate

If you click on, for instance, an AjaxInPlace, that sends a request to the server that you want to be in edit mode. The server flips its state so it is now in edit mode, but if you click a second time before the response comes back, the state has changed, so your click doesn't actually get delivered to an Ajax component. If there was no recipient of your click, it means that there also is no update container specified to be updated and your response was not turned into an AjaxResponse. This means that the second click causes the contents to be replaced with a blank. AjaxResponseDelegate looks for the confluence of all of these events and uses its fallback of pulling the update container ID out of the query parameters (generated on the Javascript side) and forces an AjaxResponse process to occur.
