This reply really helped me, thanks Jens.
Everything is working fine for a select component. The mixin seems to submit
the value to the server, but when I do the same for a checkbox or textfield, no
joy.
<t:textfield t:id="tagList" t:clientId="tagList" class="cubeAjaxUpdate"
value="cubeCard.tagList" t:mixins="jquery/bind" bind.context="cubeCard.id"
bind.event="tagListChanged" bind.eventType="change" bind.zone="gridZone"
t:zone="gridZone"/>
I know for sure that the change event is getting fired after the value has been
entered into the textfield and can see the server side handler being called,
but cubeCard.tagList is null.
Any ideas?
