Hi,
i have the next code:

SET J = CARDINALITY(OutputRoot.XML.infosIdFound_reste[]);
SET I = 1;
WHILE I <= J DO
SET OutputRoot.XML.infosIdFound_reste[I] = NULL;
SET I = I + 1;
END WHILE;
It's a single code which clean a tree with Nulls. I've follow the process with the debugger. The cardinality is 6. The trouble arrive when the i index has the value 4. The code error is 'array subscript error' when it try 'SET OutputRoot.XML.infosIdFound_reste[I] = NULL;'. Anybody know can it happend? It's very strange...

thanks

You're right!. Everytime i set nulls into the tree, the element disappear of memory. I have put:

SET J = CARDINALITY(OutputRoot.XML.infosIdFound_reste[]);
SET I = 1;
WHILE I <= J DO
SET OutputRoot.XML.infosIdFound_reste[1] = NULL;
SET I = I + 1;
END WHILE;

A lots of thanks!
