The function <eclipse-data:get-planet-data data="sundist" name="Mercury"/>
expands as follows:
connect to the database using esql and return the value as a double.
All the function does is return the value from the database without any
surronding tags.
Since I first posted this message I changed the function so that instead of
assigning mercurySun (java double variable) as follows:
mercurySun = <eclipse-data:get-planet-data data="sundist" name="Mercury"/>;
I now have:
<eclipse-data:get-planet-data data="sundist" name="Mercury"
variable="mercurySun"/>
where the function in the logicsheet assigns assigns the value. This works
fine, I'm still not that advanced in using Cocoon and so cannot workout why
I can't assign the value in the calling XSP file rather than the logicsheet.
If you can it would be aprreciated. It is a bit annoying to do the above but
it has shortend my code by quite a considerable amount compared to entering
a multitude of esql commands and logic.
Thanks
