    original bugid: #6034
    Stacktrace:

      java.lang.NullPointerException
    at java.util.Hashtable.put(Hashtable.java:375)
    at org.mmbase.module.core.MMObjectNode.storeValue(Unknown Source)
    at org.mmbase.module.core.MMObjectNode.setValue(Unknown Source)
    at org.mmbase.storage.database.SQL92DatabaseStorage.loadFieldFromTable(Unknown Source)

    at org.mmbase.bridge.implementation.BasicNodeManager.getList(Unknown Source)
    at org.mmbase.bridge.jsp.taglib.ListNodesTag.doStartTag(Unknown Source)



    This happens after doing a manual alter table, which was not smart enough evidently. But why throwing a nullpointer then.
    When 'storing' null values in a node, the field is now removed from the values list.
    This may be a step towards a databaselayer where we can actually store null values in a table (rather than storing empty strings or the numeric -1).
