I have the same problem - form fields embedded in an iterate tag.
Would it be possible to change tags such as CheckboxTag and BaseFieldTag so
that they detect when they are embedded in the "iterate" tag and format the
name attribute appropriately.
I tried changing these two tags replacing the following line in the the
doStartTag() method:
results.append(property);
With the following code and it worked well, automatically populating my
collection objects:
results.append(decideName());
/**
* Determine the name attribute
*/
private String decideName() {
// Check if this Tag is embedded in an Iterator Tag
Tag tag = findAncestorWithClass(this, IterateTag.class);
// No iterator, use the property as the name
if (tag == null)
return this.property;
IterateTag iterator = (IterateTag)tag;
int index = iterator.getLengthCount()-1;
return iterator.getProperty()+"["+index+"]."+this.property;
}

P.S. thanks for Struts - great framework.
