Converting Struts OptionsCollection tag into Options

[Oleg Konovalov]

Hi,

I wrote a [sample] simple screen with 2 html:selects [fromList, toList] and
2 buttons Add & Remove
using "htmlptionscollection" tag and now need to rework the code using
"htmlptions collection="

<html:select property='selectedFromIds' multiple="true">
<htmlptionsCollection property='fromList'/>
</html:select>


to something like [that is a piece of my existing application which I have
to follow since it already integrates to other things - gets populated from
DB, etc.]:
<html:select property="submissionType" multiple="true"
styleId="submissionTypeID">
<htmlptions 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">
<htmlptions 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;

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;

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
}

JSP:
<html:form action="/action2" method='POST'>
<table>
<tr>
<td>
<%--html:select property='selectedFromIds' multiple="true"> <!--
that how it is in my sample >
<htmlptionsCollection property='fromList'/>
</html:select--%>

<%--html:select property="submissionType" multiple="true"
styleClass="selectSmall" styleId="submissionTypeID"> <!-- that's how it is
in my Real application -->
<htmlptions collection="SubmissionType"
property="submissionTypeID" labelProperty="submissionType" />
</html:select--%>

<html:select property="selectedFromIds" multiple="true"> <!--
Shows me error that fromList bean is not declared -->
<htmlptions collection="fromList"/>
</html:select>
</td>
<td>
<input type="submit" onclick="form.action ='
action2.do?methodToCall=add'" value="Add"/>
</td>
<td>
<input type="submit" onclick="form.action
='action2.do?methodToCall=remove'" value="Remove"/>
</td>
<td>
<html:select property='selectedToIds' multiple="true"> <!--
original sample to be converted -->
<htmlptionsCollection property='toList'/>
</html:select>
</td>
</tr>
</table>
</html:form>

Any help is Very appreciated.

Thank you in advance,
Oleg.
