Hi,
by adding a button to submit the value (which did work as expected !) I found
out, that the button uses a different JScript function to submit.
Adding this to the choice tag produces the following jsp code (see below in
earlier posts for full jsp and bean code):
<tc:selectOneChoice valueChangeListener="#{myBean.processValueChange}"
value="#{myBean.choiceValue}"
id="combo1" onchange="Tobago.submitAction('combo1');">
<f:selectItems value="#{myBean.featureValue_1}" />
</tc:selectOneChoice>
This code works as expected, i.e. I click on the box, change the value, and
receive the appropriate event.
Why do I as a Tobago user have to manually add the onchange JavaScript code?
Is this the way it is supposed to work ? I don't have to do it with the buttton
!
My idea of Tobago was to free me of JavaScript issues, I would have thought
that Tobago generates the
appropriate onchange tag as soon as a ChangeListener is set ...
Thanks for your patience with me, but I'd appreciate any comments on this.
Yours,
Peter
