With the new code for paged results, we noticed some irregularities with our VLV implementation. There are a number of cases where changing parts of the search when returning with the cookie does not follow the behaviour of Windows.
The following is a list of (possible) discrepancies, partly documented in the code + knownfail:
1) If an object no longer matches the original search expression, it is not re-filtered.
2) If the search expression is changed, it doesn't appear that we notice.
3) If the controls are modified, it doesn't appear that we notice.
