Re: help,use t:commandButton pass some parameter to back bean

[Richard Capraro]

Hello Kevin,
maybe you could use the "param" tag, like this

<h:commandButton id="validate" action="#{userAction.validateUser}">
 <h:outputText value="#{msg.validate}"/>
 <f:param name="id" value="#{user.id}"/>
</h:commandLink>

To get the parameter "id" in your bean, use:

FacesContext context = FacesContext.getCurrentInstance();
Map map = context.getExternalContext().getRequestParameterMap();
String employeeID = (String) map.get("id");

Hope it helps you,

Regards,
Richard Capraro
