multiple select tag

I think the usage example is wrong. I got it working like this:

<g:multiselect multiple="multiple" optionKey="id" from="${theList}"
name="selectListName"></g:multiselect>

Pamela,

<g:select/> should now work as a multi-select if the "value" attribute
is a collection. I would leave the custom <g:multiSelect/> tag alone,
since it isn't maintained as far as I know. If you have any problems
using <g:select/> as a multi-select box, then let us know. I'm
guessing this means that the documentation needs updating to reflect
the change :)

Cheers,

Peter

Ah, okay, now it works!  I added it to the documentation:
http://docs.codehaus.org/display/GRAILS/Tag+-+select

Do you mind raising an issue for the user guide? That really needs to
be updated if it doesn't mention the multi-select option.

Thanks,

Hey, it doesn't seem to be showing the already-selected items in the select tag... am I missing the correct syntax?
<g:select name="users" from="${JsecUser.list() }" value="${jsecRole.users}" optionKey="id" multiple="multiple" noSelection="['':'']"/>

Users is a TreeSet, when I print it out it does contain a user.  And JsecUser.list() is all the users in the system.

Thanks,

Pam

Try this:

> <g:select name="users" from="${JsecUser.list() }" value="${jsecRole.users*.id}" optionKey="id" noSelection="['':'']"/>

The "*." notation is called the Groovy spread operator and effectively
expands to:

  users.collect { it.id }

So basically your values need to match the option key, not the items
in the "from" list. This is also not/badly documented :( Could you
update GRAILS-2961 :)

Thanks,

Peter

Thanks!  It works.  And makes sense.  The JIRA is updated too.
