Re: DynaForms and java.util.ArrayList"

[Mark Lowe]

I'm not sure if the forEach way works with indexed form properties. I 
tried and the html:text tags seems to be a tad oblivious to the fact 
they were nested in a loop.

<form-property name="cities" type="java.util.ArrayList" />
..
//also you need to scope to session
<action path="/process-form" name="myForm" scope="session" ...

..
ArrayList cityList = new ArrayList();
cityList.add(new CityBean());
cityList.add(new CityBean());
theForm.set("cities",cityList);

//you need this too for an unknown reason
request.setAttribute("cities",cityList.toArray());
..

<logic:iterate id="city" name="myForm" property="cities">
        <html:text name="city" property="name" />
</logic:iterate>
..

I've helped a few tutorial victims with this and it works for them too.

If you have it running with the forEach tags (they work with the 
html:text or other form bits) I'd like to know..

Cheers Mark

Remove initial=""
Then in your jsp do:
<c:forEach var="blah" items="${myFormBean.map.city}">

Subject: DynaForms and java.util.ArrayList"


When I define this in my struts-config:

<form-property
     name="city"
     type="java.util.ArrayList"
     initial=""/>
I get this error:

[ServletException in:/tiles/locationselection.jsp]
Exception creating bean of class
org.apache.struts.validator.DynaValidatorForm: {1}'
 Can I access "city" using JSTL in my jsp.

What should I put in my JSP.

What am I missing?

Thanks,
Barry
