InfoPath Dev

i've created a web service for posting data to db - the ws is used as the main datasource.  i can create a form using this ws and post data with no issues.  when i add a secondary datasource (query only) for combo box lookup, form works fine.  when i add the second secondary datasource, i get the error "infopath cannot open the selected form" - no other info.  any help would be appreciated.  dr

i resolved my problem by changing the class
declaration in the web service.  i initially had a class with a reference to
an array of tracts - a class containing a string variable.  i changed the
class to reference an array of strings.  can't say i understand why my first
option doesn't work - it's a repeating section that resolves to a string.


public partial class tbl
{
    private Tracts[] TractUIDField;
.
.
.
    [System.Xml.Serialization.XmlElementAttribute("Tracts")]
    public Tracts[] Tracts
    {
        get
        {
            return this.TractUIDField;
        }
        set
        {
            this.TractUIDField = value;
        }
    }
.
.
.
}


public partial class Tracts
{
    private string TractUIDField;

    public string TractUID
    {
        get
        {
            return this.TractUIDField;
        }
        set
        {
            this.TractUIDField = value;
        }
    }
}

i changed it to use
changed to

public partial class tbl
{
    private string[] strTractField;
.
.
.
    public string [] strTract
    {
        get
        {
            return this.strTractField;
        }
        set
        {
            this.strTractField = value;
        }
    }
