Error INOXRE8816 while update node of instanse which have de

Hello.

I have instance of document with dereference within. Dereference is right and contains linked document.

Any node update, exclude update node with dereference, result in error INOXRE8816.

If break dereferense so as dereference node does not contains linked document, node update execute successfully.

Update statement
update insert attribute __Delete {1}
into input()/man
