I recently implemented a virtual table (within a table viewer) using the
ILazyContentProvider. When the program comes up, and the view containing
the table is active, the table is populated without any issues. However,
if I were to close the view and bring the view back up, the table does not
retain any of its data. If I bring up the program and the view is not
active, the same behavior occurs where no data is ever displayed.
Has anyone ran into a similar issue?
I have included an abridged version of the content provider I am using.
Any help would be greatly appreciated.
public class InventoryContentProvider
implements ILazyContentProvider, InventoryListener
{
private TableViewer m_tableViewer;
public void inputChanged(Viewer viewer, Object oldInput, Object
newInput)
{
if (oldInput != newInput && oldInput != null)
((InventoryManager)oldInput).removeInventoryListener(this);
if (newInput != oldInput && newInput != null)
((InventoryManager)newInput).addInventoryListener(this);
m_tableViewer = (TableViewer) viewer;
m_tableViewer.getTable().clearAll();
}
public void dispose() {}
@Override
public void updateElement(int index)
{
if (m_tableViewer.getContentProvider() != null) {
m_tableViewer.replace(m_tableViewer.getElementAt(index),
index);
}
}
}
