326530 - Validation chokes on empty xsd:date instance data

Status: RESOLVED FIXED

(Core Graveyard :: Web Services, defect)

Description

[Allan Beaufour]

Something goes wrong in the validation of empty instance data with type "xsd:date". The following assertion appears:
###!!! ASSERTION: |First()| called on an empty string: 'mLength > 0', file ../../../dist/include/string/nsTSubstring.h, line 201

On load I get:
nsXFormsModelElement::Rebuild()
nsXFormsModelElement::Recalculate()
nsXFormsModelElement::Revalidate()
###!!! ASSERTION: |First()| called on an empty string: 'mLength > 0', file ../../../dist/include/string/nsTSubstring.h, line 201
Break: at file ../../../dist/include/string/nsTSubstring.h, line 201
nsXFormsModelElement::InitializeControls()

And on clicking submit (wihout entering anything in the field):
nsXFormsModelElement::Recalculate()
nsXFormsModelElement::Revalidate()
###!!! ASSERTION: |First()| called on an empty string: 'mLength > 0', file ../../../dist/include/string/nsTSubstring.h, line 201
Break: at file ../../../dist/include/string/nsTSubstring.h, line 201

sounds like debugging it, at least, should be straight forward.  Reassigning to Barry.
