Hy folks,
im trying to set up an DataTable with FilterToolbar but now im stuck. I want
to use the GoAndClearFilter, and that for i have to add an additional column
to the DataTable.
Im not quiet sure, which implementation is the right one for that, but as
far as i dont want to populate any data or something i guess the
FilteredAbstractColumn is the one to go with.
So i added an FilteredAbstractColumn, auto-generated the unimplemented
methods and tried to run it, still without GoAndClearFilter, which wouldve
been the next step.
But i got following exception:
java.lang.ArrayStoreException: de.wicketgarden.table1.Table1Page$1
at de.wicketgarden.table1.Table1Page.<init>(Table1Page.java:46)
at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
...
Heres line 46 of Table1Page.java:
columnArray[4] = new FilteredAbstractColumn<DocumentLink>(new
Model<String>("")) {
private static final long serialVersionUID = 1L;
@Override
public void populateItem(Item<ICellPopulator<DocumentLink>>
cellItem, String componentId, IModel<DocumentLink> rowModel) {
// no-op
}
@Override
public Component getFilter(String componentId, FilterForm form)
{
return null;
}
};
Any suggestions on this? Does anyone know what this is caused by?
