WARNING THIS EXAMPLE IN DEVELOPMENT
You would like to be able to select all rows in a table using a single trigger.
You can put a list of items in a table and have a single column that has a checkbox in it. You can then use the index function to change the selected item.

Discussion
Note that the setvalues inside the repeat blocks do not work. I have tried to use the current() function inside the repeat like this:
ref="current()/@selected" value="'false'" />
but with no luck.
If anyone knows how to get this working, please let us know. Thanks - Dan
Alternate Way
Note: does not work inside .
Here is the workaround for this.
id="count">
nodeset="instance('count')" type="xs:integer" />
Select all repeat
ev:event="DOMActivate">
ref="instance('count')" value="0" />
while="instance('count') < count(item)">
ref="instance('count')" value="instance('count') + 1" />
ref="item[number(instance('count'))]/@selected" value="'true'" />
