I still can't find a way around this problem. This problem came up because of a workaround for another problem I posted a few weeks ago with DOM nodes not returning the Document Element as expected. This is a stability issue, not a correctness issue, so the first problem (with the DOM impl) might be easier to fix. I am using the eXist 1.0b1 release, which is probably way behind the current development release. Regards, Brian Madigan -----Brian Madigan/WebDen wrote: ----- To: exi...@li...

Single threaded access causes no problems. Maybe I'm not using the XMLDB api safely?
