Hi Christian,

thank you so very much for looking into this! I am enclosing a java class that reproduces the NPE using the 6.1 base libraries. This code assumes that you have created an 'Annotations' database with one <Annotations/> root element.

Ciao Stefano

Stefano,

sorry for the delay. Yes, this looks like a bug. To speed this up, could you provide us with a code snippet that's running out of the box? (I didn't manage to quickly reproduce the problem).

Thanks, Christian

Hi,

I am attempting to execute an XQJ prepared expression that uses an external bind variable that accepts an xml element, and inserts it into the database document:

declare variable $inserto as element(*,xs:untyped) external; let $root := basex:db('Annotations')/Annotations return (insert node $inserto into $root)

I prepare the above statement and I bind DOM element as follows (groovy syntax):

eltype = conn.createElementType(null, XQItemType.XQBASETYPE_ANYTYPE); ixpr.bindNode(new QName("inserto"), irel, eltype);

irel is dom element that serializes as follows:

<inserto id="6">  <testo>six</testo> </inserto>

unfortunately I get an NPE when I try to execute the Query:

groovy:000> rs = ixpr.executeQuery() ERROR java.lang.NullPointerException: null        at org.basex.query.item.FElem.copy (FElem.java:214)        at org.basex.query.item.FElem.copy (FElem.java:1)        at org.basex.query.item.FElem.copy (FElem.java:210)        at org.basex.query.item.FElem.copy (FElem.java:1)        at org.basex.query.expr.Constr.add (Constr.java:107)        at org.basex.query.expr.Constr.<init> (Constr.java:53)        at org.basex.query.up.Insert.atomic (Insert.java:60)        at org.basex.query.up.Insert.atomic (Insert.java:1)        at org.basex.query.expr.Expr.iter (Expr.java:53)        at org.basex.query.QueryContext.iter (QueryContext.java:322)        at org.basex.query.QueryContext.iter (QueryContext.java:290)        at org.basex.api.xqj.BXQDynamicContext.execute (BXQDynamicContext.java:247)        at org.basex.api.xqj.BXQPreparedExpression.executeQuery (BXQPreparedExpression.java:54)        at groovysh_evaluate.run (groovysh_evaluate:10)        ...

I am using BaseX 6.1

Am I doing anything wrong?

Thank you Christian it works well now.
