Bug 213486 [Markers] view descriptions wrong when grouped
I20071218-0800. When grouped the view says 'Filter matches 100 of xyz items' but below you see that there are many more items shown as the marker filter is applied per group.

Object[] cachedValues;
		MarkerSelectionEntry(MarkerItem item) {
			MarkerField[] fields = builder.getVisibleFields();
			cachedValues = new Object[fields.length];
			for (int i = 0; i < fields.length; i++) {
				cachedValues[i] = fields[i].getValue(item);
			}
		}
		/**
		 * Return whether or not the entry is equivalent to the cached state.
		 * 
		 * @param item
		 * @return boolean <code>true</code> if they are equivalent

		boolean isEquivalentTo(MarkerItem item) {
			MarkerField[] fields = builder.getVisibleFields();
			if (cachedValues.length != fields.length)
				return false;
			for (int i = 0; i < fields.length; i++) {
				if (cachedValues[i] == fields[i].getValue(item))
					continue;
				return false;
