You could also bind the target component to a managed bean and manually register a converter. Then you could use transparent attributes on the component to pass on to the converter. A custom tag would be the better approach.
<h:outputText value="#{obj.id}" binding="obj.idCmp">
<f:attribute name="custom" value="#{obj.custom}"/>
</h:outputText>
The custom attribute would be added to the component.
<f:attribute name="custom" value="#{obj.custom}"/>
</h:outputText>
The custom attribute would be added to the component.
private HtmlOutputText idCmp = null;
public HtmlOutputText getIdCmp() {
if (idCmp == null) {
idCmp = new HtmlOutputText();
}
if (idCmp.getConverter() == null) {
MyConverter converter = new MyConverter();
converter.setCustom((String) idCmp.getAttributes("custom"));
idCmp.setConverter(converter);
}
}
public void setIdCmp(HtmlOutputText id).....
