ArrayList set method in nested bean- confusion
I have a nested bean where beanA (courseBean) stores an ArrayList of bean2
(event).
I can dump out the ArrayList no problem but I can't seem to make the set
method run. So here are some code snippits.
JSP
<logic:notEmpty name="courseEventForm" property="courseBean.events">
<html:text name="courseEventForm" property='<%= "courseBean.events[" + cnt
+ "].startDate" %>' size="12" maxlength="12"/>
</logic:iterate>
So produces HTML
<input type="text" name="courseBean.events[0].startDate" maxlength="12"
size="12" value="">
<input type="text" name="courseBean.events[1].startDate" maxlength="12"
size="12" value="">
etc
In formbean
public CourseEventForm () {
this.course = new Course(this);
}
etc
In my Course Bean set/get methods
public Course (CourseEventForm parent) {
this.parentBean = parent;
this.eventList = new ArrayList();
}
public Object[] getEvents() {
return eventList.toArray();
}
public void setEvents(Object[] newEventList) {
this.eventList = new ArrayList();
for (int i=0; i<newEventList.length; i++) {
this.eventList.add(newEventList[i]);
}
}
I'm basically trying to implement an add button which adds another instance
of an event in the form but
I get array out of bounds error. If the set method ran it should increase
the array length as it needs - I'm thinking.
Any one know what's going wrong here - do I need another method in the
Course Bean
Thanks

yes the code was ok - in fact the issue was the fact the formBean was in
request scope in struts-config.xml - changing it to session sorted it out

should be fine.. to add a new row you can do so using the set's on the
formBean in you action class...
