<nomatch>
The <nomatch> element is short for <catch event=“nomatch”>.
Attributes
| count | (defaults to 1) The occurrence of the event. The count allows you to handle different occurrences of the same event differently. Each <form>, <menu>, and form item maintains a counter for each event that occurs while it is being visited; these counters are reset each time the <menu> or form item's <form> is re-entered. The form-level counters are used in the selection of an event handler for events thrown in a form-level <filled>. Counters are incremented against the full event name and every prefix matching event name; for example, occurrence of the event “event.foo.1” increments the counters associated with handlers for “event.foo.1” plus “event.foo” and “event”. |
| cond | (defaults to true) An expression that must evaluate to true after conversion to Boolean in order for the event to be caught. |
