public class SkipValidators extends TagHandler
The <o:skipValidators>
taghandler allows the developer to entirely skip validation when
executing an UICommand
or ClientBehaviorHolder
action. This taghandler must be placed inside an
UICommand
or ClientBehaviorHolder
component (client behavior holder components are those components
supporting <f:ajax>
).
For example, when adding a new row to the data table, you'd like to not immediately validate all empty rows.
<h:form> <h:dataTable value="#{bean.items}" var="item"> <h:column> <h:inputText value="#{item.value}" required="true" /> </h:column> </h:dataTable> <h:commandButton value="add new row" action="#{bean.add}"> <o:skipValidators /> </h:commandButton> <h:commandButton value="save all data" action="#{bean.save}" /> <h:messages /> </h:form>
Note that converters will still run and that model values will still be updated. This behavior is by design.
