Bug #1578

Updated by Michael Kay almost 12 years ago

The following query (taken from W3C FOTS:fn-function-lookup-314) causes Saxon to throw an IllegalState exception: 

 <pre> 
 function-lookup(fn:QName('http://www.w3.org/2005/xpath-functions', 'unordered'), 1)(1) 
 </pre> 

 The problem occurs with all "compile-time functions" - those that are normally processed entirely at compile time. Apart from unordered(), other examples include true(), false(), and static-base-uri().  

 The stack trace of the exception thrown is as follows: 

 <pre> 
 java.lang.IllegalStateException: Function unordered should have been resolved at compile-time
