Hi,
I wrote a simple screen with 2 html:selects [fromList, toList] and 2 buttons
Add & Remove
using html:optionscollection tag and now need to rework the code using
"html:options collection="
<html:select property='selectedFromIds' multiple="true">
<html:*optionsCollection* property='fromList'/>
</html:select>
to something like [that is a piece of my existing application which I have
to follow]:
<html:select property="submissionType" multiple="true"
styleId="submissionTypeID">
<html:*options* collection="SubmissionType" property="submissionTypeID"
labelProperty="submissionType" />
</html:select>
where the only related thing I have declared in the Form is:
public String submissionType[];
SubmissionType is a Class SubmissionType:
public class SubmissionType {
private String submissionType;
private String submissionTypeID;
... getters & setters
}
I tried directly:
<html:select property='selectedFromIds' multiple="true">
<html:*options Collection=*'fromList'/>
</html:select>
So how do I convert the tags and probably the Java code as well ?
HTTP error:500 JspException: Cannot find bean under name fromList,
although have List fromList = form.getFromList();
The original sample code is below:
Action:
public class StrutsAction2 extends DispatchAction {
public ActionForward init(ActionMapping actionMapping, ActionForm
actionForm, HttpServletRequest httpServletRequest, HttpServletResponse
httpServletResponse) throws Exception {
System.out.println("In Init");
ControlForm form = (ControlForm)actionForm;
List fromList = form.getFromList();
fromList.clear();
fromList.add(new LabelValueBean("v1", "k1"));
fromList.add(new LabelValueBean("v2", "k2"));
fromList.add(new LabelValueBean("v3", "k3"));
return actionMapping.findForward("init");
}
public ActionForward add(ActionMapping actionMapping, ActionForm
actionForm, HttpServletRequest httpServletRequest, HttpServletResponse
httpServletResponse) throws Exception {
System.out.println("In Add");
ControlForm form = (ControlForm)actionForm;
List fromList = form.getFromList();
List toList = form.getToList();
String[] selectedFromIds = form.getSelectedFromIds();
for(int i=0; i < selectedFromIds.length; i++) {
String id = selectedFromIds[i];
Iterator iterator = fromList.iterator();
boolean ok = false;
while(iterator.hasNext() && !ok) {
LabelValueBean lvb = (LabelValueBean)iterator.next();
if(lvb.getValue().equalsIgnoreCase(id)) {
if(!toList.contains(lvb)) {
toList.add(lvb);
}
ok = true;
}
}
}
return actionMapping.findForward("add");
}
public ActionForward remove(ActionMapping actionMapping, ActionForm
actionForm, HttpServletRequest httpServletRequest, HttpServletResponse
httpServletResponse) throws Exception {
System.out.println("In Remove");
ControlForm form = (ControlForm)actionForm;
List toList = form.getToList();
String[] selectedToIds = form.getSelectedToIds();
for(int i=0; i < selectedToIds.length; i++) {
String id = selectedToIds[i];
Iterator iterator = toList.iterator();
boolean ok = false;
while(iterator.hasNext() && !ok) {
LabelValueBean lvb = (LabelValueBean)iterator.next();
if(lvb.getValue().equalsIgnoreCase(id)) {
iterator.remove();
ok = true;
}
}
}
return actionMapping.findForward("remove");
}
}
Form:
public class ControlForm extends ActionForm {
private String[] selectedFromIds;
private String[] selectedToIds;
private List fromList = new ArrayList();
private List toList = new ArrayList();
... getters/setters
}
