Hi Jeff, thanks for your answer. I was already doing that, using two
actions (well, using two different methods of a LookupAction), one to
initialize the list and the other to process it, but the problem arises
when I submit the form in "page.jsp".

When I have this sort of thing, I usually put it in an "initializer"
Action that I always link to in place of the JSP.
<action path="initPage" name="BasicContentForm" validate="false"
type="com.example.InitAction">
<!-- This action populates the form -->
<forward path="page.jsp" redirect="false" name="success" />
</action>
<action path="processPage" name="BasicContentForm" validate="true"
input="initPage.do" ...>
<!-- this action processes the form -->
</action>

Hi! I have a problem with form members initialization.
I have this form.
public class BasicContentForm extends ValidatorForm {
protected java.util.List propertyValues;
public BasicContentForm() {
this.propertyValues = new java.util.ArrayList();
}
public void setPropertyValues( java.util.List propertyValues ) {
this.propertyValues = propertyValues;
} public java.util.List getPropertyValues() {
return this.propertyValues;
}
public Object getPropertyValue(int index) {
return propertyValues.get(index);
}
public void reset(ActionMapping mapping, HttpServletRequest
request) {
this.propertyValues = new java.util.ArrayList();
}
}
And this jsp:
<logic:iterate name="basicContentForm" property="propertyValues"
id="propertyValue">
<html:text name="propertyValue" property="value" indexed="true"/>
</logic:iterate>
The problem is that the number and type of the elements of
propertyValues list is calculated dynamically (from the database). I
was doing that on my Action class, but I've realized that this
doesn't work: when I submit the form, I get an Exception at
BeanUtils.populate, because the list is not properly initialized. If
I can't initialize it on the reset() method (I need to access the
database), what else can I do?
Thanks in advance
