我有一种情况，我需要知道在更改模式下要安装/卸载哪些功能，因此我将能够修改对话框序列。

我的设置包括 2 个功能F_WEB_APP和F_DATABASE，为了让我的生活更轻松，我在自定义对话框的下一步按钮上发布了以下属性，以根据功能条件确定哪些功能已安装、要安装或要卸载，如下所示：

<Publish Dialog="CustomizeDlg" Control="Next" Property="IsDBInstalled" Value="Yes" Order="5"><![CDATA[!F_DATABASE > 2]]></Publish>
<Publish Dialog="CustomizeDlg" Control="Next" Property="IsDBInstalled" Value="No"  Order="6"><![CDATA[!F_DATABASE < 3]]></Publish>

<Publish Dialog="CustomizeDlg" Control="Next" Property="IsWebInstalled" Value="Yes" Order="7"><![CDATA[!F_WEB_APP > 2]]></Publish>
<Publish Dialog="CustomizeDlg" Control="Next" Property="IsWebInstalled" Value="No" Order="8"><![CDATA[!F_WEB_APP < 3]]></Publish>                

<Publish Dialog="CustomizeDlg" Control="Next" Property="IsDBSelected" Value="Yes" Order="9"><![CDATA[&F_DATABASE > 2]]></Publish>
<Publish Dialog="CustomizeDlg" Control="Next" Property="IsDBSelected" Value="No" Order="10"><![CDATA[&F_DATABASE < 3]]></Publish>

<Publish Dialog="CustomizeDlg" Control="Next" Property="IsWebSelected" Value="Yes" Order="11"><![CDATA[&F_WEB_APP > 2]]></Publish>
<Publish Dialog="CustomizeDlg" Control="Next" Property="IsWebSelected" Value="No" Order="12"><![CDATA[&F_WEB_APP < 3]]></Publish>

在第一次安装期间，我的所有属性都根据用户选择（预期行为）进行设置，但在更改/修改期间它们仅设置一次（在自定义对话框首次加载 - 值匹配现有状态，无论用户更改如何）！如果用户进行更改并按下一步或继续然后返回并更改所选功能并单击下一步，则没有设置任何属性...这里有什么问题？

首次安装的日志（为便于阅读而修剪）：

正如您从第二个日志中看到的那样，没有记录属性更改，我在这里缺少什么？

谢谢。

经过几个小时的阅读，我空手而归！我在任何地方都找不到任何解决方案。

好消息是我自己想出了一个解决方案（不理想），但它有效！！！！

每个功能都有几个与之链接的组件，但我至少有一个与该功能一起存在的非条件组件（例如注册表组件），在放弃获取要更新的功能请求/操作状态后，我尝试了组件请求/操作状态..是的，它已更新。

因此，我将条件基于组件请求/操作状态而不是功能请求/操作状态，如下所示：

<!--If one of Database feature required components request state is Local or Source or Default. it means install.-->
<Publish Dialog="CustomizeDlg" Control="Next" Property="InstallDatabase" Value="1" Order="5"><![CDATA[$CMP_DATABASE_REGISTRY > 2]]></Publish>
<!--else clear the propery.-->
<Publish Dialog="CustomizeDlg" Control="Next" Property="InstallDatabase" Order="6"><![CDATA[$CMP_DATABASE_REGISTRY < 3]]></Publish>

<!--If one of Database feature required components request state is Absent. it means uninstall.-->
<Publish Dialog="CustomizeDlg" Control="Next" Property="UninstallDatabase" Value="1" Order="7"><![CDATA[$CMP_DATABASE_REGISTRY = 2]]></Publish>
<!--else clear the property .-->
<Publish Dialog="CustomizeDlg" Control="Next" Property="UninstallDatabase" Order="8"><![CDATA[$CMP_DATABASE_REGISTRY <> 2]]></Publish>


<!--If one of WebApp feature required components request state is Local or Source or Default. it means install.-->
<Publish Dialog="CustomizeDlg" Control="Next" Property="InstallWebApp" Value="1" Order="9"><![CDATA[$CMP_WEB_APP_REGISTRY > 2]]></Publish>
<!--else clear the propery.-->
<Publish Dialog="CustomizeDlg" Control="Next" Property="InstallWebApp" Order="10"><![CDATA[$CMP_WEB_APP_REGISTRY < 3]]></Publish>

<!--If one of WebApp feature required components request state is Absent. it means uninstall.-->
<Publish Dialog="CustomizeDlg" Control="Next" Property="UninstallWebApp" Value="1" Order="11"><![CDATA[$CMP_WEB_APP_REGISTRY = 2]]></Publish>
<!--else clear the property .-->
<Publish Dialog="CustomizeDlg" Control="Next" Property="UninstallWebApp" Order="12"><![CDATA[$CMP_WEB_APP_REGISTRY <> 2]]></Publish>

注意：如果用户没有对选择树进行任何更改，功能组件的操作/请求状态将是未知的 = -1。

现在我可以使用上述属性在更改/修改模式下对对话框进行排序：

<!--collect WebApp setting if WebApp to be installed, WebAppDlg will handle where to go next.-->
<Publish Dialog="CustomizeDlg" Control="Next" Event="NewDialog" Value="WebAppDlg" Order="13"><![CDATA[Installed AND InstallWebApp]]></Publish>
<!--collect Database setting if WebApp not to be installed and Database to be installed or uninstalled, DatabaseDlg will handle where to go next.-->
<Publish Dialog="CustomizeDlg" Control="Next" Event="NewDialog" Value="DatabaseDlg" Order="14"><![CDATA[Installed AND NOT InstallWebApp AND (InstallDatabase OR UninstallDatabase)]]></Publish>
<!--user made no changes go to verify ready dialog.-->
<Publish Dialog="CustomizeDlg" Control="Next" Event="NewDialog" Value="VerifyReadyDlg" Order="15"><![CDATA[Installed AND NOT InstallWebApp AND NOT InstallDatabase]]></Publish>
