Is this something that might be handled by a "normal" mapped property with an
additional property for getting the names of all the dynamic fields?
public Object getDynamicField(String key) {
return this.map.get(key);
}
public void setDynamicField(String key, Object value) {
this.map.put(key, value);
}
public Set getDynamicFieldNames() {
return this.map.keySet();
}
But your JSP doesn't know the field names ahead of time, so it can't "ask" for
them by name, right? So maybe something like this would work:
<logic:iterate id="fieldName" name="theForm" property"dynamicFieldNames">
<html:text property='<%= "dynamicField(" + fieldName + ")" %>'/>
</logic:iterate>
