Hi, I'm currently building a site based on PageTypeBuilder and also Composer.

Everything works like charm except that every time i rebuild the solution all properties when editing a page using the composertab is gone, the Content tab is empty. http://i.imgur.com/3nbTF.jpg

If I go inteo adminmode and then to the composer block type, I can see the properties there, and if i chose to edit them, and then save them they will be accessable in edit mode.

The code for the composer function.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using PageTypeBuilder;
using EPiServer.Core;
using EPiServer.SpecializedProperties;

namespace PageTypes.Composer
{
    [PageType(
        "4271667E-E3C0-48b1-80E4-0E914B4B0620",
        Name = "[ExtensionSys] Puff",
        Description = "Displays a single puff",
        SortOrder = 60,
        Filename = "/UserControls/Composer/PuffFunction.ascx")]
    public class PuffFunctionType : ComposerFunctionPageTypeBase
    {
        [PageTypeProperty(
            EditCaption = "Header",
            HelpText = "Sets the puffs header",
            UniqueValuePerLanguage = true,
            Searchable = true,
            SortOrder = 50,
            DisplayInEditMode = true,
            Type = typeof(PropertyString),
            Tab = typeof(ComposerTab))]
        public virtual string Header { get; set; }

        [PageTypeProperty(
            EditCaption = "Bodytext",
            HelpText = "Sets the puff body text",
            UniqueValuePerLanguage = true,
            DisplayInEditMode = true,
            Searchable = true,
            SortOrder = 125,
            Type = typeof(PropertyXhtmlString),
            Tab = typeof(ComposerTab))]
        public virtual string MainBody { get; set; }

        [PageTypeProperty(
            EditCaption = "Image",
            HelpText = "Sets the puffs image",
            DisplayInEditMode = true,
            Searchable = false,
            Type = typeof(PropertyImageUrl),
            Tab = typeof(ComposerTab))]
        public virtual string Image { get; set; }

        [PageTypeProperty(
            EditCaption = "Link",
            HelpText = "Sets the link for the puff",
            UniqueValuePerLanguage = true,
            DisplayInEditMode = true,
            Searchable = false,
            Type = typeof(PropertyUrl),
            Tab = typeof(ComposerTab))]
        public virtual string Link { get; set; }
    }
}

Any idea why this might happen?
