[Solved] Autocomplete Bound to DNN Web API service works in Chrome/IE but not Firefox

[Mike]

Hello,

I'm using a DotNetNuke 7.0 webservice and calling it from the autocomplete text box. I have a more complex version, but even this simple one isn't working:

Copy code

<telerik:RadAutoCompleteBox runat="server" ID="test">
    <WebServiceSettings Method="AutocompleteSearchUsers"Path="http://localhost/DesktopModules/CoreServices/API/UserService" />
</telerik:RadAutoCompleteBox>

I am getting a result from the service that comes in XML - here's an example result I got from firebug:

Copy code

<AutoCompleteBoxData xmlns:i="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://schemas.datacontract.org/2004/07/Telerik.Web.UI">
<Context xmlns:d2p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays"></Context>
<Items>
<AutoCompleteBoxItemData>
<Attributes xmlns:d4p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays"></Attributes>
<Enabled>true</Enabled>
<Text>Mike TEST Ryckman</Text>
<Value>22173</Value>
</AutoCompleteBoxItemData>
<AutoCompleteBoxItemData>
<Attributes xmlns:d4p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays"></Attributes>
<Enabled>true</Enabled>
<Text>Kirssa Cline Ryckman</Text>
<Value>29</Value>
</AutoCompleteBoxItemData>
<AutoCompleteBoxItemData>
<Attributes xmlns:d4p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays"></Attributes>
<Enabled>true</Enabled>
<Text>Kirssa Cline Ryckman</Text>
<Value>42</Value>
</AutoCompleteBoxItemData>
<AutoCompleteBoxItemData>
<Attributes xmlns:d4p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays"></Attributes>
<Enabled>true</Enabled>
<Text>Mike Ryckman</Text>
<Value>3</Value>
</AutoCompleteBoxItemData>
<AutoCompleteBoxItemData>
<Attributes xmlns:d4p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays"></Attributes>
<Enabled>true</Enabled>
<Text>Kirssa Ryckman</Text>
<Value>24</Value>
</AutoCompleteBoxItemData>
</Items>
</AutoCompleteBoxData>

Here's the method being called:

<DnnAuthorize()>
<HttpPost()>
Public Function AutocompleteSearchUsersTest(context As RadAutoCompleteContext) As AutoCompleteBoxData
    Const MaxRecords As Integer = 5
    Const MinLength As Integer = 2
    Dim serializer As New JavaScriptSerializer
    Dim data As Dictionary(Of String, Object)
    Dim searchString As String

    Try
        data = serializer.Deserialize(Of Dictionary(Of String, Object))(context("context").ToString)
        searchString = data("Text").ToString()
    Catch ex As Exception
        searchString = ""
    End Try

    Dim output As New AutoCompleteBoxData
    If searchString.Length >= MinLength Then
        Dim results As New List(Of AutoCompleteBoxItemData)
        Dim searchOutput As IEnumerable(Of UserInfo) = TestableUserController.Instance.GetUsersAdvancedSearch(PortalSettings.PortalId, UserController.GetCurrentUserInfo.UserID, -1, -1, -1, False, 0, 10, "LastName", True, "DisplayName", searchString).Take(MaxRecords)

        Dim curResult As AutoCompleteBoxItemData

        For Each curUser In searchOutput
            curResult = New AutoCompleteBoxItemData
            curResult.Text = curUser.DisplayName
            curResult.Value = curUser.UserID
            results.Add(curResult)
        Next
        output.Items = results.ToArray
    End If
    Return output
End Function

But, the autocomplete box doesn't populate or display results. When I look in the code, the UL (racList) doesn't get any items added to it and it never displays.

All of the exact same stuff works in both Chrome and IE. 

Any idea what's happening here? I noticed in the web service demo on your site that the results are in a JSON format...; could that be the problem?

Thanks,

Mike
