Subject Re: [trinidad 1.2] <tr:table> docs, rowselection, sorting, pagenation, filtering?
Date Fri, 08 Jul 2011 10:26:08 GMT

1/ I don't know of a good CollectionModel subclassing example. Anyway,
I never really had the need for it. If you need to load rows on demand
and such, you may as well subclass List

2/ Don't forget in your <tr:column> to set sortable="true" AND
sortProperty="someAttribute", where "someAttribute" is the property
name of the row object (NOT an EL) :
<tr:table var="order" value="#{myBean.orders}"...>
<tr:column sortable="true" sortProperty="date">  <!-- refers to . If myBean.orders is a List<Order>, then this will use
Order.getDate() to get the value for sorting-->

3/ This is tricky to find. It's a skinning feature. See . You have
to define a subclass of ResourceBundle that provides an array of keys
and translations, like this :
public class Traduction extends ListResourceBundle

	protected Object[][] getContents()
		// TODO Auto-generated method stub
		return _CONTENTS;
	static private final Object[][] _CONTENTS =
      {"af_tableSelectMany.SELECT_COLUMN_HEADER", "change me !"},
      {"af_tableSelectOne.SELECT_COLUMN_HEADER", "change me !"},
The trickiest part of it is that the keys are often not documented,
you have to scan the source code to find them...

4/ Again you should find all you ned in the skinning section
5/ Not that I know of. The 2 bars are rendered as two different html tables
6/ Sounds fine to me. I'd simply use a list and put the filtering
stuff in a bean, though. Unless you plan to componentize your filtered
