[Xsltforms-support] XPath concat problem

[Grégoire C. <gco...@gm...>]

Hi!

I upgraded to revision 523 and I now get an error during initialization:

Binding evaluation didn't returned a nodeset but '  ' for XPath
expression: concat( substring(instance('instance-annonces')/annonce[id =
instance('instance-annonce-selectionnee')/id]/prix,string-length(instance('instance-annonces')/annonce[id
= instance('instance-annonce-selectionnee')/id]/prix)-8, 3) , ' ' ,
substring(instance('instance-annonces')/annonce[id =
instance('instance-annonce-selectionnee')/id]/prix,string-length(instance('instance-annonces')/annonce[id
= instance('instance-annonce-selectionnee')/id]/prix)-5, 3) , ' ' ,
substring(instance('instance-annonces')/annonce[id =
instance('instance-annonce-selectionnee')/id]/prix,string-length(instance('instance-annonces')/annonce[id
= instance('instance-annonce-selectionnee')/id]/prix)-2, 3) )

This ugly XPath is used to separate large numbers in (up to) 3 groups of
numbers (1234567 is displayed as 1 234 567). I know I could do this
differently, but for now, I'd like to know why this doesn't work anymore?

Thanks,
Grégoire
