I am using GlazedListsSortModel for my SortHeaderLayer and my own custom IColumnPropertyAccessor and IDataProvider for body data and column header.
My data has a dynamic number of columns which changes on user interaction.
Whenever a column is added/removed I fire a doCommand(new StructuralRefreshCommand()) on the nattable.
Everything works great, except that any of the dynamically added columns are not sortable. When I click on their column header to initiate sorting, I get the following exception:
!MESSAGE Unhandled event loop exception

Apparently the GlazedListsSortModel does not update during the StructuralRefreshCommand. Can anyone give me a hint how I can fix this?
Any help is greatly appreciated.

Hi Dirk,
I have worked around it now by writing a wrapper for GlazedListsSortModel that has a refresh method that I call whenever a structural refresh happens. It then recreates the sortmodel if the number of columns changed and then reapplies the sorted by column (if possible):
class GlazedListsSortModelWrapper<T> implements ISortModel {
SortedList<T> sortedList;
IColumnPropertyAccessor<T> columnPropertyAccessor;
IConfigRegistry configRegistry;
DefaultColumnHeaderDataLayer columnHeaderDataLayer;
int oldColumnCount;
GlazedListsSortModel<T> model;
public GlazedListsSortModelWrapper(SortedList<T> sortedList,
IColumnPropertyAccessor<T> columnPropertyAccessor,
IConfigRegistry configRegistry,
DefaultColumnHeaderDataLayer columnHeaderDataLayer) {
this.sortedList=sortedList;
this.columnPropertyAccessor = columnPropertyAccessor;
this.configRegistry = configRegistry;
this.columnHeaderDataLayer = columnHeaderDataLayer;
model = new GlazedListsSortModel<T>(sortedList,
columnPropertyAccessor, configRegistry, columnHeaderDataLayer);
oldColumnCount = columnPropertyAccessor.getColumnCount();
}
public void refresh() {
int newColumnCount = columnPropertyAccessor.getColumnCount();
if (newColumnCount==oldColumnCount)
return;
List<Integer> sortedColumnIndices = model.getSortedColumnIndexes();
SortDirectionEnum sortDir = null;
if (sortedColumnIndices.size()>0)
sortDir = model.getSortDirection(sortedColumnIndices.get(0));
model = new GlazedListsSortModel<T>(sortedList,
columnPropertyAccessor, configRegistry, columnHeaderDataLayer);
if (sortedColumnIndices.size()>0 && sortedColumnIndices.get(0)<newColumnCount)
model.sort(sortedColumnIndices.get(0),sortDir,false);
oldColumnCount = newColumnCount;
}
@Override
public void clear() {
model.clear();
}
@Override
public List<Comparator> getComparatorsForColumnIndex(int arg0) {
return model.getComparatorsForColumnIndex(arg0);
}
@Override
public SortDirectionEnum getSortDirection(int arg0) {
return model.getSortDirection(arg0);
}
@Override
public int getSortOrder(int arg0) {
return model.getSortOrder(arg0);
}
@Override
public List<Integer> getSortedColumnIndexes() {
return model.getSortedColumnIndexes();
}
@Override
public boolean isColumnIndexSorted(int arg0) {
return model.isColumnIndexSorted(arg0);
}
@Override
public void sort(int arg0, SortDirectionEnum arg1, boolean arg2) {
model.sort(arg0,arg1,arg2);
}
}
As you say it would be nice if this could be fixed in GlazedListsSortModel. I'll watch the bug and go back to a cleaner solution if it gets fixed.
Thanks,
Timm
