多视图未在 Ektron 页面构建器小部件中的回发上运行脚本

我的 Ektron 页面构建器小部件遇到了一个奇怪的问题。

无论出于何种原因，当我从小部件内切换小部件视图的任何按钮回发到服务器时，这些视图中的脚本不会执行。

控制小部件处于什么"模式"的多视图似乎是表面值的常规多视图，所以我不确定为什么它会以这种方式运行。我已经通过向页面添加第二个多视图来测试这一点，该多视图只执行交换视图和警报，当放置在小部件外部的模板上时，它按预期工作，但在小部件内部无法执行其脚本。此外，当在小部件内单击任何按钮时，ektron 会打开一个加载图像，无论单击哪个多视图，该图像都会在服务器回发时消失。这让我相信 Ektron 正在积极采取措施来抑制这些小部件脚本的执行，尽管我什至不确定它会如何去做，因为脚本在渲染后会在视图中正确显示。

小部件代码：

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="TestWidget.ascx.cs" Inherits="widgets_TestWidget" %>
<asp:MultiView ID="ViewSet" runat="server" ActiveViewIndex="0">
    <asp:View ID="View" runat="server">
        <script>alert('this runs');</script>
        <asp:Label ID="OutputLabel" runat="server"></asp:Label>
    </asp:View>
    <asp:View ID="Edit" runat="server">
        <div id="<%=ClientID%>_edit">
            <script>alert('but for some reason, this does not run');</script>
            <asp:TextBox ID="HelloTextBox" runat="server" Style="width: 95%"> </asp:TextBox>
            <asp:Button ID="CancelButton" runat="server" Text="Cancel" OnClick="CancelButton_Click" />
            &nbsp;&nbsp;
                <asp:Button ID="SaveButton" runat="server" Text="Save" OnClick="SaveButton_Click" />
        </div>
    </asp:View>
</asp:MultiView>
<!--code below works properly outside of the widget and fails inside of it -->
<asp:MultiView ID="uxmulti" runat="server" ActiveViewIndex="0">
    <asp:View ID="view1" runat="server">
        <script>alert('this runs');</script>
        <asp:Button ID="ux_b1" runat="server" OnClick="ux_b1_Click" Text="to edit" />
    </asp:View>
    <asp:View ID="edit1" runat="server">
        <script>alert('as does this, but not inside the widget');</script>
        <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="to view" />
    </asp:View>
</asp:MultiView>

这可以使用肮脏的 eval 语句来解决，但这远非理想。关于为什么会以这种方式行事或如何解决它的任何想法？
