How to handle NULL's in the first row of a SharePoint list using an XML data source?
I recently started creating SSRS 2005 reports against WSS 3.0 SP1 lists using an XML data source. I've found that if a value of a field in the first row of the data source is NULL, then the entire field for every row is dropped.
When the report is previewed, no values show up for that field in any row. If the fields are refreshed in the data tab, these fields drop out and the report encounters errors when previewing. If the value in the first row is not NULL, data shows up even if subsquent rows have NULL values.
Other than requesting a default value for a field (which I don't have any control over) is there an alternative method for ensuring that the field doesn't get dropped once the data is brought over to SSRS?
Is this related to "nillable"? Can a .rdl field be edited?
Does this occur in other versions of SSRS or SharePoint?
