Hi folks,
I have a working Action and JSP form that I'm using for creating new
entities in my very basic Struts 2.2.1.1 app. I'm trying to modify
the app to re-use the JSP form with editing of entities. I added a
hidden "ID" tag and now I'm getting errors when I submit the form.
Can someone please give me some assistance? I've Googled this issue
and seen others posting similar errors but I'm not sure how to resolve
it.
Excerpt from Stack Trace when I submit the form:

ModelDriven<Tag> {
Tag tag = new Tag();
public Tag getTag() {
return tag;
}
public void setTag(Tag tag) {
this.tag = tag;
}
public String createTag() {
...
}
}
Excerpt from POJO:
public class Tag implements java.io.Serializable {
private int id;
private String name;
public int getId() {
return this.id;
}
public void setId(int id) {
this.id = id;
}
...
}
Excerpt from Struts.xml
<action name="saveOrUpdateTag"
class="org.robbins.flashcards.presentation.TagAction"
method="createTag">
<result name="success" type="tiles">displaytag.tiles</result>
<result name="input" type="tiles">tagform.tiles</result>
</action>
