org.zkoss.zk.ui.sys.DesktopCtrl.invokeExecutionCleanups()

Invokes {@link org.zkoss.zk.ui.util.ExecutionCleanup#cleanup} for each relevantlistener registered by {@link Desktop#addListener}.

Used only internally.

It never throws an exception but logs and adds it to the errs argument, if not null. @param exec the execution that is being destroyed @param parent the previous execution, or null if no previous at all @param errs a list of exceptions (java.lang.Throwable) if any exceptionoccured before this method is called, or null if no exeption at all. Note: you can manipulate the list directly to add or clean up exceptions. For example, if exceptions are fixed correctly, you can call errs.clear() such that no error message will be displayed at the client. @since 3.0.6
