It's a long time ago, but I do have a recollection that there was a problem at one stage that you could create two instances of the objects representing built-in atomic types such as xs:string, and they didn't compare equal to each other. It might be that problem.

I would recommend at the very least moving to the latest maintenance release in the 9.0.0 series, which I think was 9.0.0.8, released on 2008-09-01. The current release is 9.4.0.6.

Hello,

 

we are using Saxon 9.0.0.2 in one of our XSLT server products.

Sometimes after a restart of the XSLT server Saxon fails to execute the transformation and displays error message like:

 

"Cannot compare xs:string to xs:string"

 

This error message is display when stylesheet code like this is executed:

<xsl:when test="xs:string(number(sum(current-group()/G2ShipmentOrderLineGoodsItemLevel/KP/KPAQAC))) != 'NaN'">

 

 

The same transformation is running fine when we restart the XSLT server again.

Is there a known race condition in Saxon 9.0.0.2 which can lead to such issues?

 

Mit freundlichen Grüßen / best regards
