Ah, you're right - I think I'm missing a vital part of my setup - the
function to select the stuff in the right hand boxes! What a foolish
schoolboy error. Thanks very much.

RE: dynamic alteration of multiple entry select box content with javascript : empty values upon submission
You have to select all the options before submit like this:
function activateOptions(field){
for(i=0;imailto:[EMAIL PROTECTED]]

Hello.
I have an html page with two select boxes configured to allow multiple
selection in each. The one on the left contains options that are available,
the one on the right contains options that are selected from those
available. I've got a javascript method suite that will transfer selected
options from the box on the left to the box on the right dynamically. I
know it works with normal html form submission as I've used it many times
in the past. Now however I'm trying to get it to work with struts.
The first problem I came across was populating the select boxes. Not
normally a problem, but the form bean I had configured to accept the data
from the html page complained about various problems. Finally I got this
nailed. Here's an example of the html:
Available options
Selected options/td>
(please excuse any shonky indentation :)
I won't paste the javascript functions up here as they're pretty long
winded.
The top select box gets its options from a bean containing a collection of
LabelValue beans. The bottom select box gets it options from a collection
contained in the form bean, which is populated from the database with an
Action before the form is rendered.
Now, if you click one of the two buttons labelled >> or << the options move
across into the relative box as expected. But when I submit the form I am
getting nothing at all in the form bean for either the property
"allOptions" or "selectedOptions". Nothing at all, not a null value, just
nothing. This is independant of the type that you set that field to in the
form bean class you make - struts isn't doing anything clever like turning
the multiple selection into a Vector on the fly for you.
The selected options should come through as a comma seperated list of IDs.
If anybody has any idea where to go I would be very helpful, as reading
through the mailing list archive and checking google hasn't really given me
any useful information. Is there anywhere I can check every value being
gleaned out of the form by the controller servlet? Printing the query
string out in the action class that the html page forwards off to doesn't
help, it's empty too.
Regards,
Simon
