Turyn, Michael commented on XAP-263:
------------------------------------
A few current (as of 29-01-07) error messages are attached in
"DS_error_messages.txt". They are still not exceptionally helpful, but are
more informative than before---notably (for the case originating this bug
report, no data source at all):
Exception:Bad attribute with name dataSource and value myDataSource on element
<binding xmlns="http://openxal.org/core/data"; id="employeeCount"
dataSource="myDataSource" select="concat('# Items:
',count(/employees/employee))"/> because of Exception: TypeError -
_10a.messages has no properties
...---most especially the first line (which could be improved with quotes
around the attribute name and value), and...
Exception:Error calling method:bind
Caused by:
Exception:Named context for quick binding not found for 'myDataSource'.
> DataBinding: Bad error message when no document data sources exist and one is
> needed
