It's pretty easy with EL. Using the c:forEach tag the varStatus (which contains the index of the current iteration) is assigned to the name loop. Then, in the form fields the loop.index is inserted into the form field name using EL. E.g. people[${loop.index}].username will translate at runtime into people[0].username, people[1].username etc.

The relevant section of the ActionBean:
| Code Block |
|---|
| title | Map/Indexed properties with String keys in the ActionBean |
|---|
|
private Map<String,Double> toolParameters;
public Map<String,Double> getToolParameters() { return toolParameters; }
public void setToolParameters(Map<String,Double> toolParameters) {
this.toolParameters = toolParameters;
}
|
...
The last point is worth explaining in more detail. What is means is that you can have ActionBean properties that looks like this:
| Code Block |
|---|
public Map<Date,List<Appointment>> getAppoinments() { return appointments; }
public void setAppoinments(Map<Date,List<Appointment>> appointments) {
this.appointments = appointments;
}
|
and have input fields that look like this:
| Code Block |
|---|
|
Note: <stripes:text name="appointments[${date}][${idx}].note"/>
|
