    Codefirst CheckBoxList and prevalues seem to need a comma in the array element?

    Hi all,

    I came across a strange problem the other day that I'm hoping is something that I've missed rather than a bug in Contour, so perhaps one of you lovely people could let me know!  I'm creating a checkboxlist on a codefirst contour page, however I found that if I don't have a comma within the value entered into the array for the prevalues, that I get a:

    Object of type 'System.String' cannot be converted to type 'System.Collections.Generic.List`1[System.String]'

    error, however if I add a comma to the text in the array it works fine.  To show you what I mean, the first code block below causes the error:

    [Field(FormPages.Callout,
                   FormFieldsets.Signup, 
                   Type = typeof(CheckBoxList),
                   Prevalues = new[] { "Yes", "No" })]
            public List<string> Member { get; set; }

    However this one is fine, notice the addition of an extra comma after Yes and No:

    [Field(FormPages.Callout,
                   FormFieldsets.Signup, 
                   Type = typeof(CheckBoxList),
                   Prevalues = new[] { "Yes,", "No," })]
            public List<string> Member { get; set; }

     

    Anyone able to shed some light on this or suggest an alternative approach?

    Many Thanks.

    Hi Simon,

    Just tested and it should work without the extra comma

    When exactly are you getting the error, could you post a stacktrace

    I tried created a new form code first with your example and that works...

    Looks like it is happening in the validate method, so might be a bug there, checking it out now

    Ok can confirm that it's a bug, happens when you only select 1 item in the checkboxlist

    Ok think I found a fix :)

    Could you try downloading http://nightly.umbraco.org/Umbraco%20Contour/3.0.10%20WIP/

    UmbracoContour_3.0.10 WIP_update.zip

    And you'll just need to deploy Umbraco.Forms.CodeFirst.dll to your bin directory

    Let me know if that fixes the issue for you

    Cheers,
    Tim
