Hi everyone. I’m new to the list. :)
I’m working on a new Struts 2 application (my first). I have quite a bit of
experience with Struts 1.x.
I have a need to administer a set of rules, which are essentially name/value
pairs. The number of rules is dynamic. I have a POJO class called Rule that
has getters and setters for name and value.
On my Action, I have a List property with corresponding get and set methods:
> public List<Rule> getRules() {
> return rules;
> }
>
> public void setRules(List<Rule> rules_) {
> rules = rules_;
> }
>
> private List<Rule> rules;
On my JSP, I have the following block of code:
> <div id="results">
> <s:iterator value="rules" status="status">
> <div class="resultRow">
> <div class="name">
> <s:textfield name="name" />
> </div>
> <div class="value">
> <s:textfield name="value" />
> </div>
> </div>
> </s:iterator>
> </div>
The page renders as expected, but when I submit the page, ParametersInterceptor
logs the following error messages:
> [setParameters]: Unexpected Exception caught setting 'name' on 'class
> com.blah.BlahAction: Error setting expression 'name' with value
> '[Ljava.lang.String;@1fbc95c'>
>
> [setParameters]: Unexpected Exception caught setting 'value' on 'class
> com.blah.BlahAction: Error setting expression 'value' with value
> '[Ljava.lang.String;@160cd93'>
What am I doing wrong? I've tried several other approaches (indexed and mapped
setters, and changing the name properties on the textfield tags accordingly),
but I did some googling and found this:
http://www.mail-archive.com/user@struts.apache.org/msg60905.html. It seems to
me that the approach I described above is the same as the one described in that
message.
I'm thinking this is a typical greenie mistake, and I'm hoping someone here can
set me straight.
Thanks,
Jake Robb
