Yes, this is a bug. We are already tracking it internally, but it is not yet fixed.
Thanks, -Danny From: [email protected] [mailto:[email protected]] On Behalf Of Andreas Hubmer Sent: Monday, December 14, 2015 8:45 AM To: MarkLogic Developer Discussion Subject: [MarkLogic Dev General] XDMP-EXTVAR with xdmp:spawn-function and external variables Hi, It seems that I've found a bug concerning spawned functions and external variables. In a module with an external variable I spawn a function. The spawned function calls another function which fails with XDMP-EXTVAR when accessing the external variable. Here is a small example (main.xqy): xquery version "1.0-ml"; declare variable $param as xs:string external; declare function local:func() { xdmp:log("value: " || $param) }; xdmp:spawn-function(function() { local:func() }) I call main.xqy using the following snippet: xquery version "1.0-ml"; xdmp:invoke("main.xqy", (xs:QName("param"), "foo")) This leads to the following error: XDMP-EXTVAR: (err:XPDY0002) declare variable $param as xs:string external; -- Undefined external variable fn:QName("","param") I've also found out that accessing the external variable directly in the spawned function works. Working version of main.xqy: xquery version "1.0-ml"; declare variable $param as xs:string external; xdmp:spawn-function(function() { xdmp:log("value: " || $param) }) Regards, Andreas -- Andreas Hubmer IT Consultant
