Hi!
I use
Tomcat 6
myFaces 1.2.2
tomahawk 1.1.6
I tried do create a Converter for following model:
public class PlanningPoint {
private String country;
private String location;
private String street;
private String postCode;
private String houseNumber;
private String identifier;
public PlanningPoint(final String country, final String location, final
String street,
final String postCode, final String houseNumber) {
super();
this.country = country;
this.location = location;
this.street = street;
this.postCode = postCode;
this.houseNumber = houseNumber;
}
public PlanningPoint() {
}
public String toString() {
return this.country + ";" + this.location + ";" + this.street +
";" +
this.postCode + ";"
+ this.houseNumber + ";" + this.identifier;
}
public String getCountry() {
return this.country;
}
public void setCountry(final String country) {
this.country = country;
}
public String getLocation() {
return this.location;
}
public void setLocation(final String location) {
this.location = location;
}
public String getStreet() {
return this.street;
}
public void setStreet(final String street) {
this.street = street;
}
public String getPostCode() {
return this.postCode;
}
public void setPostCode(final String postCode) {
this.postCode = postCode;
}
public String getHouseNumber() {
return this.houseNumber;
}
public void setHouseNumber(final String houseNumber) {
this.houseNumber = houseNumber;
}
public String getIdentifier() {
return this.identifier;
}
public void setIdentifier(final String identifier) {
this.identifier = identifier;
}
}
Thats the converter:
public class PlanningPointConverter implements Converter {
public Object getAsObject(final FacesContext context, final UIComponent
component, final String value) {
if (value == null) {
return new PlanningPoint();
} else if (value.isEmpty()) {
return new PlanningPoint();
}
PlanningPoint p = new PlanningPoint();
try {
String [] pComps = StringUtility.split(value, ";");
p.setCountry(pComps[0]);
p.setLocation(pComps[1]);
p.setStreet(pComps[2]);
p.setPostCode(pComps[3]);
p.setHouseNumber(pComps[4]);
p.setIdentifier(pComps[5]);
} catch (ConverterException e) {
e.printStackTrace();
}
return p;
}
public String getAsString(final FacesContext context, final UIComponent
component, final Object value) {
if (value.equals("") || value == null) {
return "";
} else {
}
PlanningPoint p = (PlanningPoint) value;
String s = "";
try {
s = ((PlanningPoint) value).toString();
} catch (ConverterException e) {
e.printStackTrace();
}
return s;
}
}
jsp snippet:

controller snippet:
public class PlanningController {
private boolean renderGeoDropDownStart;
private boolean renderGeoDropDownEnd;
private List<SelectItem> geoEndDropDownList;
private PlanningPoint geoEndtDropDownSelected;
private List<SelectItem> geoStartDropDownList;
private PlanningPoint geoStartDropDownSelected;
public void geocodeStart(final ActionEvent event) {
try {
this.setDropDownGeo(this.model.geocode(this.startPoint),
PlanningController.DropDown.GEO_START);
this.startPoint = new PlanningPoint();
this.renderGeoDropDownStart = true;
} catch (WebserviceException e) {
UIComponent component =
ComponentSupport.getComponentById("subViewPlanning:fPlanning");
ComponentSupport.showMessageFromBundle(component,
"errorMsgWebservice");
}
}
public void geocodeEnd(final ActionEvent event) {
try {
this.setDropDownGeo(this.model.geocode(this.endPoint),
PlanningController.DropDown.GEO_END);
this.endPoint = new PlanningPoint();
this.renderGeoDropDownEnd = true;
} catch (WebserviceException e) {
UIComponent component =
ComponentSupport.getComponentById("subViewPlanning:fPlanning");
ComponentSupport.showMessageFromBundle(component,
"errorMsgWebservice");
}
}
private void setDropDownGeo(final List<PlanningPoint> l, final DropDown
d)
{
List<SelectItem> tmpList = new LinkedList<SelectItem>();
tmpList.add(new SelectItem(""));
for (PlanningPoint p : l) {
this.geoStartDropDownSelected = p;
tmpList.add(new SelectItem(p, p.getIdentifier()));
}
switch (d) {
case GEO_START:
this.geoStartDropDownList.addAll(tmpList);
break;
case GEO_END:
this.geoEndDropDownList.addAll(tmpList);
break;
default:
break;
}
}
public List<SelectItem> getGeoEndDropDownList() {
return this.geoEndDropDownList;
}
public void setGeoEndDropDownList(final List<SelectItem>
geoEndDropDownList) {
this.geoEndDropDownList = geoEndDropDownList;
}
public PlanningPoint getGeoEndtDropDownSelected() {
return this.geoEndtDropDownSelected;
}
public void setGeoEndtDropDownSelected(final PlanningPoint
geoEndtDropDownSelected) {
this.geoEndtDropDownSelected = geoEndtDropDownSelected;
}
public List<SelectItem> getGeoStartDropDownList() {
return this.geoStartDropDownList;
}
public void setGeoStartDropDownList(final List<SelectItem>
geoStartDropDownList) {
this.geoStartDropDownList = geoStartDropDownList;
}
public PlanningPoint getGeoStartDropDownSelected() {
return this.geoStartDropDownSelected;
}
public void setGeoStartDropDownSelected(final PlanningPoint
geoStartDropDownSelected) {
this.geoStartDropDownSelected = geoStartDropDownSelected;
}
public boolean isRenderGeoDropDownStart() {
return this.renderGeoDropDownStart;
}
public void setRenderGeoDropDownStart(final boolean
renderGeoDropDownStart)
{
this.renderGeoDropDownStart = renderGeoDropDownStart;
}
public boolean isRenderGeoDropDownEnd() {
return this.renderGeoDropDownEnd;
}
public void setRenderGeoDropDownEnd(final boolean renderGeoDropDownEnd)
{
this.renderGeoDropDownEnd = renderGeoDropDownEnd;
}
}
If I tried out this at the first (meaning loading values from one of the
renderGeoDropDownStart) all work correctly but if I reload
renderGeoDropDownStart nothing occur - That means no CommandButton works or
the reloading is completed.

Severity: ERROR
Message: subViewPlanning:fPlanning:planGeoDropdown1: Validierungsfehler:

(in english I think thats mean: validation error: value is not a valid
