Bug 356800

Description Christoph Thommen 2011-09-06 08:02:10 EDT

When hitting F5 on a Node with some Sub-Nodes (Node-Page), a NullPointerException in SwtScoutTableModel#getCell occurs.

There are some timing-prolems. It can happen, that the object (row) passed to getCell is outdated an not in m_cachedCells any more, so refreshing the cache doesn't solve this.
