Trigger to set multiple values at once

Hi All,

This seems like it should be really simple to do, but does anyone know
how I can make a trigger to set multiple values at once?
For example, in a table where each row has a boolean element(represented
as a checkbox), and I'd like to make a trigger to
check all of the checkboxes at once (i.e. setting all boolean values to
'1').

Say I had a list of Invoice elements each with a Mailed boolean element,

<Invoice><Mailed>0</Mailed></Invoice>
<Invoice><Mailed>0</Mailed></Invoice>
<Invoice><Mailed>0</Mailed></Invoice>
<Invoice><Mailed>0</Mailed></Invoice>
...

and I want to set all the Mailed elements to 1, is that possible?

I tried <xforms:setvalue ref="Invoice/Mailed" value="'1'"/>  It only set
the first Mailed element, and not the rest of them.

Thanks in advance for any suggestions.

Larry,
        You need to create a looping actions using xforms:dispatch to go
through each position of the <Invoice> and change them one by one.

There is a @while in xforms:action that can be used to do this, but its from
the 1.1 spec and not currently supported by Orbeon

I hate to contradict you, but it is supported ;-)

You could write something like:

<xforms:setvalue while="Invoice/Mailed[. = 0]"
                  ref="Invoice/Mailed[. = 0]"
                  value="1"/>
