Hi,
Just answered a similar question on another thread which I think may help
here too. As long as you are using a version of AppFuse which uses Spring
2.0.x you should be using the Spring form tags to do all the hard work for
you (I have adjusted the stuff below to match your JSP). I also notice you
seem to have a form specific backing object - as a rule I try and design my
systems to edit the model objects directly. Spring does most of the work,
and it leads to a dramatic reduction in code.
From other thread (edited):
Hmm. In that case you might want to take a look at Spring's form tags to
make life a little easier:
http://static.springframework.org/spring/docs/2.0.x/reference/spring-form.tld.html
So your JSP would look something like:
<spring:form commandName="engagementform" ...>
...
<spring:select path="systems" items="${webSystemImpacted}"
itemLabel="name" itemValue="id"/>
....
</spring:form>
A lot simpler and Spring will do all the hard work for you. It should all
just work like magic. I think the problem in your code is the name you
attach to the select element - Spring expects specific names to get its
bindings sorted out.
