I'm using NetUI in a Weblogic Portal 10.2 portlet and I'm trying to make
sure my datagrid has a default order.
Hence the following begin action:
@Jpf.Action(
forwards={
@Jpf.Forward(name="index", action = "sortOpenCalls")
}
)
protected Forward begin()
{
Forward forward = new Forward("index");
//by default, order by descending date
DataGridConfig config = DataGridConfigFactory.getInstance();
Sort sortDate = config.createSort();
sortDate.setDirection(SortDirection.DESCENDING);
sortDate.setSortExpression("latestInformationIssueDate");
List<Sort> sorts = Arrays.asList(new Sort[]{
sortDate
});
SortModel sortModel = config.createSortModel(sorts);
DataGridState dataGridState =
DataGridStateFactory.getInstance(getRequest()).getDataGridState("openCallsGrid");
dataGridState.setSortModel(sortModel);
return forward;
}
Then the sortOpenCalls action loads the data and actually applies the sort:
@Jpf.Action(forwards = { @Jpf.Forward(name = "success", path =
"BrowseOpenCalls.jsp", actionOutputs = { @Jpf.ActionOutput(name =
"openCalls", type = eu.europa.ec.digit.cap.portal.dto.CallListItem[].class,
required = true), @Jpf.ActionOutput(name = "latestDatesOfCallPublications",
type = java.util.Date[].class, required = true) }) })
public Forward sortOpenCalls() {
Forward forward = new Forward("success");
DataGridState dataGridState =
DataGridStateFactory.getInstance(getRequest()).getDataGridState("openCallsGrid");
List<Sort> sorts = dataGridState.getSortModel().getSorts();
List<Comparator> comparators = new ArrayList<Comparator>();
if(sorts != null){
for(final Sort sort:sorts){
comparators.add(new Comparator(){
public int compare(Object o1, Object o2) {
try {
if(sort.getDirection() == SortDirection.NONE){
return 0;
} else if(sort.getDirection() ==
SortDirection.ASCENDING){
return BeanUtils.getSimpleProperty(o1,
sort.getSortExpression()).compareTo(BeanUtils.getSimpleProperty(o2,
sort.getSortExpression()));
} else if(sort.getDirection() ==
SortDirection.DESCENDING){
return -BeanUtils.getSimpleProperty(o1,
sort.getSortExpression()).compareTo(BeanUtils.getSimpleProperty(o2,
sort.getSortExpression()));
} else return 0;
} catch (IllegalAccessException e) {
return 0;
} catch (InvocationTargetException e) {
return 0;
} catch (NoSuchMethodException e) {
return 0;
}
}
});
}
}
CallListItem[] openCalls = callService.getOpenCalls();
if(comparators.isEmpty()){
forward.addActionOutput("openCalls", openCalls);
} else {
List<CallListItem> sortedOpenCalls = new
ArrayList(Arrays.asList(openCalls));
Collections.sort(sortedOpenCalls,
ComparatorUtils.chainedComparator(comparators));
forward.addActionOutput("openCalls", sortedOpenCalls.toArray(new
CallListItem[0]));
}
Date[] dates = callService.getLatestDatesOfCallPublications();
forward.addActionOutput("latestDatesOfCallPublications", dates);
return forward;
}
Unfortunately, when the portlet loads, it is well sorted by
latestInformationIssueDate BUT in ASCENDING order instead of DESCENDING
order.
Any idea what I did wrong?
