Guys, I'm not quite sure what the problem here is. I got sorting in t:dataTable
working quite quickly once I figured out how t:dataTable was supposed to be
used.
I started with the Seam messages example app, and here is my solution:
@Name("sort")
| public class Sort
| {
| private String column;
| private boolean ascending;
|
| public boolean isAscending()
| {
| return ascending;
| }
| public void setAscending(boolean ascending)
| {
| this.ascending = ascending;
| }
| public String getColumn()
| {
| return column;
| }
| public void setColumn(String column)
| {
| this.column = column;
| }
|
| private void sort(List data)
| {
| Collections.sort(data, new Comparator<Message>() {
|
| public int compare(Message x, Message y)
| {
| if (!ascending)
| {
| Message temp = y;
| y = x;
| x = temp;
| }
| if ("title".equals(column))
| {
| return x.getTitle().compareTo(y.getTitle());
| }
| else if ("datetime".equals(column))
| {
| return x.getDatetime().compareTo(y.getDatetime());
| }
| else
| {
| return new Boolean( x.isRead() ).compareTo( y.isRead() );
| }
| }
|
| });
| }
|
| @DataModel
| public Object getMessageList()
| {
| List data = .....; //get the list of messages!
| sort(data);
| return data;
| }
|
| @DataModelSelection
| private Message selectedMessage;
|
| public void print()
| {
| System.out.println(selectedMessage.getTitle());
| }
|
| //Add in other event listeners here!!!!
| }
Then messages.jsp was modified to look like:
<t:dataTable var="msg" value="#{sort.messageList}"
| sortColumn="#{sort.column}" sortAscending="#{sort.ascending}"
preserveSort="true">
| <h:column>
| <f:facet name="header">
| <t:commandSortHeader columnName="read" arrow="true">
| <h:outputText value="Read"/>
| </t:commandSortHeader>
| </f:facet>
| <h:selectBooleanCheckbox value="#{msg.read}" disabled="true"/>
| </h:column>
| <h:column>
| <f:facet name="header">
| <t:commandSortHeader columnName="title" arrow="true">
| <h:outputText value="Title"/>
| </t:commandSortHeader>
| </f:facet>
| <h:commandLink value="#{msg.title}" action="#{sort.print}"/>
| </h:column>
| <h:column>
| <f:facet name="header">
| <t:commandSortHeader columnName="datetime" arrow="true">
| <h:outputText value="Date/Time"/>
| </t:commandSortHeader>
| </f:facet>
| <h:outputText value="#{msg.datetime}">
| <f:convertDateTime type="both" dateStyle="medium"
timeStyle="short"/>
| </h:outputText>
| </h:column>
| </t:dataTable>
I guess the only "trick" I used here was to stick the @DataModel annotation on
a getter method instead of on an instance variable.
Perhaps this solution should be added to the wiki....
