MMBase

Remarekd in a 1.7 installation:

 <mm:listnodescontainer type="object">
    <mm:constraint field="owner" value="m.meeuwissen" />
    <mm:constraint field="number" value="33148965" operator="GREATER" />
    <mm:sortorder field="number" />
    Size: <mm:size />
    <mm:maxnumber value="100" />
    <table>
      <mm:listnodes>
        <mm:deletenode deleterelations="true" />Deleted.</td></tr>
      </mm:listnodes>
</mm:listnodescontainer>

Gives exception when it encounters a relations (probagbly one which was just dleted because of the 'deleterelations=true'.
