<rich:column's attribute comparator not working

lilyju Aug 31, 2012 11:03 AM

Hi,

I have followed this example to do my sorting on a column: http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=dataTable&sample=tableSorting&skin=blueSky

but the column does not sort, I have seen my comparator being called.

My Bean:

public Ordering getSubmittedBySort() {

return SubmittedBySort;

}

public void setSubmittedBySort(Ordering sort) {

this.SubmittedBySort = sort;

}

public Comparator<ApprovalsTableBean> getDateSubmittedComparator() {

return new Comparator<ApprovalsTableBean>() {

public int compare(ApprovalsTableBean a1, ApprovalsTableBean a2) {

return a1.getDateSubmitted().compareTo(a2.getDateSubmitted());

}

};

}

My xhtml:

<rich:column styleClass="#{approvals.rowcolor}" width="10%" sortBy="#{approvals.dateSubmitted}" sortOrder="#{manageOutstandingApprovals.dateSubmittedSort}" comparator="#{manageOutstandingApprovals.dateSubmittedComparator}" >

<f:facet name="header">

<h:outputText value="#{messages['outstandingApprovals.dateSubmitted']}"/>

</f:facet>

<h:outputText value="#{approvals.dateSubmitted}" id="col3"/>

/rich:column>

Does anyone have a working example? Thank you in advance. Lily

I solved myself, here is my code:

In my xhtml:

//always load the list
<head>#{manageOutstandingApprovals.loadOutstandingApprovals}</head>

<rich:column styleClass="#{approvals.rowcolor}" width="5%" comparator="#{manageOutstandingApprovals.comparator}" sortBy="#{approvals.dateOutstanding}" sortOrder="#{manageOutstandingApprovals.numOutstandingSort}">
              <f:facet name="header">

                <h:outputText styleClass="wrapcn" value="#{messages['outstandingApprovals.daysOutstanding']}"/>

              </f:facet>
              <h:outputText value="#{approvals.dateOutstanding}" id="col9"/>
            </rich:column>

in my bean:

public String getLoadOutstandingApprovals() {

        if (listOfApprovals != null && organizationID == selectedOrgID)
            return "";

        List<OutstandingApprovalsSearchResults> searchResults = new ArrayList<OutstandingApprovalsSearchResults>();
        listOfApprovals = new ArrayList<ApprovalsTableBean>();
......
}

public Comparator<ApprovalsTableBean> getComparator() {

        Collections.sort(listOfApprovals, new MyComparable());
        return null;
    }

class MyComparable implements Comparator<ApprovalsTableBean>{

        @Override
        public int compare(ApprovalsTableBean a1, ApprovalsTableBean a2) {

             int tz1Int = Integer.valueOf(a1.getDateOutstanding().split(DAY_HOUR_SEPARATOR)[0]);
             int tz2Int = Integer.valueOf(a2.getDateOutstanding().split(DAY_HOUR_SEPARATOR)[0]);

            if (NumOutstandingSort.equals(Ordering.ASCENDING)) {

                if (tz1Int == tz2Int) {
                    return 0;
                }
                if (tz1Int > tz2Int) {
                    return -1;
                } else {
                    return 1;
                }
            }
            else {
                if (tz1Int == tz2Int) {
                    return 0;
                }
                if (tz2Int > tz1Int) {
                    return -1;
                } else {
                    return 1;
                }
            }

        }

    }
