Table repeat bind

Hi again,

I don't know if it is posible to change a value of a xforms:output inside a repeat table and automatically update all other xforms:outputs of the table. Let me explain:
I am implementing a personal agenda using a table and if the user wants to add an event at a certain time all the future events must change its time automatically. I know this can be implemented with a submission, but can be implemented using a bind?

Thanks again!
Jordi

Jordi,

I don't see why you wouldn't be able to do this, but could you provide a
concrete example? It is hard to explain things in a complete vacuum.

Dear Erik, sorry for my explanations...

I've prepared an example xsl. Basically it shows a table with an event
scheduling, where for each row we have begin hour, duration, name of the
event and two buttons: insert and remove.
For each row (or event) we calculate the hour as previous row hour +
previous row duration.

What I need is when the user presses insert or remove button, change
automatically the scheduling of ALL the future events. Now I am able to
change only the next row.
I have put a bind using the index of the repeat, but I don't know if I can
put a loop in the bind or something similar. I hope you can test it easily.

Regards,
Jordi

Jordi,

This is an easy one. Think in terms of the XML document (XForms
instance) rather than in terms of xforms:repeat:

<xforms:bind
   nodeset="Event/@hour"
   readonly="false()"
   calculate="if (count(../preceding-sibling::Event) > 0)
              then (../preceding-sibling::Event[1]/@hour
                    + ../preceding-sibling::Event[1]/@duration)
              else ."
   constraint=". castable as xs:dateTime"/>
