Is there a convenient way to pass parameters to messages from resource bundle to components other than h:outputFormat?
For instance, this is legal:
<h:outputFormat value="#{myBundle['parametricMessage']}">
<f:param value="#{myBundle['someParameterValue']}"/>
</h:outputFormat>
But I need it for a button, like this (which won't work):
<h:commandButton value="#{myBundle['parametricMessage']}">
<f:param value="#{myBundle['someParameterValue']}"/>
</h:commandButton>
Of course, I can use link instead of button, and I can make it through a property in a managed bean, but in this question I'm seeking for a convenient way to use the button...
I'm using RichFaces 3.3.3, JSF2, facelets.
How about this approach ?
EL expression allow you to define a function .You first define a EL expression 's function , which accepts a resource bundle , its message key and placeholder 's parameter and output the resolved message .
public static String geti18nMsg(ResourceBundle bundle ,String msgKey, String paramValue ) {
String msgValue = bundle.getString(msgKey);
MessageFormat messageFormat = new MessageFormat(msgValue);
Object[] args = {paramValue};
return messageFormat.format(args);
}
Then call this function to get the resolved message in the <h:commandButton>
:
<h:commandButton value="#{f:geti18nMsg(myBundle , parametricMessage, someParameterValue)}"/>
