public class ERXHyperlink

extends WOHyperlink

Enhancement to WOHyperlink. Don't use this class directly, it is patched automatically into the runtime system on application startup. Just use WOHyperlink.

• Puts a description of the action into the session under the key ERXActionLogging
• When the disabled is true, then returns context().page() instead of the normal WONoContentElement. The rationale is that in almost all cases you don't want your users to see an empty page, especially not in the typical case when you show a list paginator and disable the link to the current item.
• When you have action targets inside of the hyperlink, then their invokeAction() method is normally never called. This is probably an optimization, but breaks the case when you have - say - onClick elements inside of the hyperlink. This subclass will instead propagate the invokeAction to the children if the senderID() starts with the elementID() (which should indicate an action inside of a hyperlink).
