The problem is, the generated names of the HTML form elements do not
correspond to the names of properties of your ActionForm.
Here a sample, how this can be done:
<logic:iterate name="myForm" property="elements" id="element" indexId="i"
type="de.grayman.test.struts.MyElement">
<tr>
<td>
<html:checkbox property='<%= "element[" + i + "].member" %>' />
<html:hidden property='<%= "element[" + i + "].elementName" %>' />
</td>
<td><bean:write name="element" property="elementName" /></td>
<td><bean:write name="element" property="elementDescription" /></td>
</tr>
</logic:iterate>
In the MyForm class, there have to be two properties (getter methods):
1) the collection "elements"
2) indexed property "element"
private Vector elements;
public Collection getElements() {
return this.elements;
}
public MyElement getElement(int i) {
while (getGroups().size() <= i) {
this.element.add(new MyElement());
}
return (MyElement) this.elements.get(i);
}
Note: Class MyElement has read/write properties member, elementName,
elementDescription, ...
Note: The getElement(int i) fills the Vector with empty elements, if they do
not exist.
In this way, the form will be filled correcly from the submitted HTML-Form. Of
course,
you could use another approach, e.h. HashTable or an Array instead of Vector.
