Ah - I got the idea. I worked out the following, and I think it would be
instructive to include it in myfaces example.
public String getColumnDataType() {
String columnDataType = null;
return getColumnValue().getClass().getName();
}
public boolean isBooleanValue() {
return getColumnDataType() == "java.lang.Boolean" ;
}
public boolean isStringValue() {
return getColumnDataType() == "java.lang.String" ;
}
Many thanks.
Regards,
Yee

Subject: Re: How to handle Boolean/Checkboxes in <t:columns>?
you can switch it by using the rendered attribute. Provide some is
methods for the datatype and check it through the rendered attribute.
Put them inside the t:columns component. You can nest them into
h:panelGroup if you have more than one component to render for a
specific datatype.
<h:selectBooleanCheckbox rendered="#{userRolesBean.booleanValue}"
value="#{userRolesBean.columnValue}"/>
<h:inputText rendered="#{userRolesBean.stringValue}"
value="#{userRolesBean.columnValue}"/>
