Description

TextContraints are wrongly encoded as REGEX filter by the SPARQL query util.

here an example

SELECT DISTINCT ?id
WHERE {
 {
   ?id

{field}

?tmp1  
     FILTER(regex(str(tmp1,"

{regex}","i")) .
 }
}
LIMIT 10

the correct FILTER expression would be

FILTER(regex(str(?tmp1),"{regex}

","i")) .

so basically the '?' before the variable name tmp1 as well as the closing bracket for the str function are missing.

This should be fixed both in trunk and the 0.12.0 releasing branch
