Strange behavior of commandButton

Dear fellows,

I dont know why but some times this happens. you press command Button but the action method associated with that button is not called, and the same page is only refreshed. Can anybody tell me why this happens because it does not give any kind of error or warnings.

thanx in advance

use <h:message showSummary="true" showDetail="true" /> to see if there are any conversion errors.

This can occur if any validation or conversion error has occurred and you haven't definied a h:message component for the appropriate UIInput component or a h:messages component.To test it, add <h:messages /> to the form.
