Re: how to disable the table while it is empty in wicket

[kumar ramanathan]

Hi Martin,

I have added that code in the dataview as below.

dataView = new DataView<List&lt;AssignmentDB>>("AssignmentList", new
ListDataProvider(assignments)) {
                       public void onConfigure() {
                         *super.onConfigure();* *//am getting error here*
                          setVisible(getDataProvider().size() > 1);
                        } 
                       public void populateItem(Item<List&lt;AssignmentDB>> 
item) {
                       .............
                       }
      };

Also in the above code in the thread above , i have add a assignmentdb
object with empty values before form submit code, so it is loaded a table
with empty row. while onsubmit i have removed the list values and populate
the table with new values. I believe I should not add the empty values
first.How to correct this ,i have done this because wicket says
labels,dataview Ids are not defined,dataview should not be null am not aware
of how to handle the null values.  please advice and help me. 

code snap:

assignments.add(new AssignmentDB());
             dataView = new DataView<List&lt;AssignmentDB>>("AssignmentList", 
new
ListDataProvider(assignments)) {
             public void populateItem(Item<List&lt;AssignmentDB>> item) {
                  final AssignmentDB  assign = (AssignmentDB) 
item.getModelObject();
            
                item.add(new Label("AOmemberId", assign.getMemberId()));
                item.add(new Label("AOlossId", assign.getLossId()));

          }};
