Subject Issue with Struts2 s:select tag with Object inside a Model Object
Date Sat, 01 Apr 2017 23:37:55 GMT
Hi,

I am trying to use the Struts2 s:select tag but the drop down value coming
from the db is not being set to the drop down as selected value and the
screen always shows the default first value in the list.

Can some one please help me.

*JSP Code*

<s:select name="diagnosisDTO.primaryDiagnosis"
   list="primaryDiagnosisTypes"
   listKey="dstLookupTypeId"
   listValue="lookupValue"
   multiple="false"
   headerKey="-1"
   headerValue="Please Select"
   size="1"/>

*Action Class Code*


*I have Disease Tracking as a Model object and inside that model I have
DiagnosisDTO object where I have properties which are matched  to the jsp
select tag above*




*This is the Model Object defined in the Action Class    public
DiseaseTracking getModel() {        return this.diseasetracking;    }*

*DiseaseTracking Object with DiagnosisDTO property below *








*private DiagnosisDTO diagnosisDTO; public DiagnosisDTO getDiagnosisDTO()
{  return diagnosisDTO; } public void setDiagnosisDTO(DiagnosisDTO
diagnosisDTO) {  this.diagnosisDTO = diagnosisDTO; }*


*DiagnosisDTO Object with property **primaryDiagnosis **and getter and
setter*




* private int primaryDiagnosis; public int getPrimaryDiagnosis() {  return
primaryDiagnosis; }*




* public void setPrimaryDiagnosis(int primaryDiagnosis)
{  this.primaryDiagnosis = primaryDiagnosis; }*


*This method is a service call to get the disease tracking object*
























* public String getHepC() throws Exception {  List allDstLookupTypes =
GenCache.getListOfDstLookupType(user.getCurrentClientId());
 setPrimaryDiagnosisTypes(this.getSpecificDstLookupTypes(Constants.DST_LOOKUP_GRP_CODE_ID_PRD,
allDstLookupTypes));  DiseaseTrackingDelegate dstDelegate = new
DiseaseTrackingDelegate();  int dstId = 20000048;  //The below is the
service call to db which will get the disease tracking object with some
lists objects.   diseasetracking =
dstDelegate.getDSTById(user.getCurrentClientId(), dstId, null);  //the
below is the code to convert the list returned from service to another
object Diagnosis DTO and set that back to Disease Tracking model
object  convertDiagnosisListToDiagnosisDTO(diseasetracking.getAlDstLookup());
 return
"success"; } public List<DstLookupType> getSpecificDstLookupTypes(String
grpLookupTypeId, List<DstLookupType>
allDstLookupTypes){ List<DstLookupType> lookupTypes = new
ArrayList<DstLookupType>(); for(int i=0; i <
allDstLookupTypes.size();i++) {  if(
allDstLookupTypes.get(i).getDstLookupGrpCodeId().equals(grpLookupTypeId)){
  lookupTypes.add(allDstLookupTypes.get(i));  } } return
lookupTypes;}*
