[xslt] Incomplete error message "Error Invalid type"

["Thomas Mauch" <thomas mauch calanda-technology com>]

Title: Message

Hello,

when I tried to work with a result tree without using the node-set function, I noticed that in some circustances an incomplete error message is created which does not indicate where the error happened, but just the message text "Error Invalid type".

Please have a look the attached code snipped. When the now commented value-of call is executed, a "good" error message is created:

 

Error Invalid type
runtime error: file node-set-error.xslt line 16 element value-of
xsltValueOf: text copy failed

On the other hand, if the value-of is executed within the for-each loop as it is shown in the code, an incomplete error message just saying

 

Error Invalid type

is created. This makes debugging quite hard.

Thomas
