Hi, I'm using tr:tree through my own TreeModel since a long time. Now I
noticed a problem when underlying data can change dynamically. This
occurs when method getRowCount() returns a given number of nodes, but
then some of them are deleted from the underlying business layer. In
such case, method isRowAvailable() returns false for missing nodes.
Then we get an exception "String index out of range" in IconRenderer
#88, since it does not check for an empty icon name (since there is no
icon for the missing node).
How should it work in such cases ? Should I *always* return -1 from
getRowCount() when the node collection is expected to change ?
