我看到WiX的一些奇怪行为让我头疼。
业务规则：允许用户覆盖安装目录。 允许用户覆盖配置文件安装目录(使用安装目录作为之前设置的默认路径)。
对话框流如下所示(标记如下)：WelcomeDlg->InstallDirDlg->LogConfigDlg
<UI Id="MyWixUI_InstallDir">
<UIRef Id="WixUI_InstallDir" />
<!--Add default dialogs: BrowseDlg, DiskCostDlg, InstallDirDlg, InvalidDirDlg, LicenseAgreementDlg, WelcomeDlg, VerifyReadyDlg, etc.-->
<!--<DialogRef Id="AppConfigDlg" />-->
<!-- Override the next and back buttons on the WelcomeDlg and InstallDirDlg to skip the License agreement page of the installer -->
<Publish Dialog="WelcomeDlg" Control="Next" Event="DoAction" Value="regSetINSTALLDIR" Order="1">PREVIOUSINSTALLFOLDER</Publish>
<Publish Dialog="WelcomeDlg" Control="Next" Event="NewDialog" Value="InstallDirDlg" Order="2">NOT Installed</Publish>
<Publish Dialog="InstallDirDlg" Control="Back" Event="NewDialog" Value="WelcomeDlg" Order="1">1</Publish>
<Publish Dialog="InstallDirDlg" Control="Next" Event="DoAction" Value="SetLOGCONFIGDIR" Order="2">WIXUI_DONTVALIDATEPATH OR WIXUI_INSTALLDIR_VALID="1"</Publish>
<Publish Dialog="InstallDirDlg" Control="Next" Event="DoAction" Value="regSetLOGINSTALLDIR" Order="3">PREVIOUSLOGINSTALLFOLDER</Publish>
<Publish Dialog="InstallDirDlg" Control="Next" Event="NewDialog" Value="LogConfigDlg" Order="4">WIXUI_DONTVALIDATEPATH OR WIXUI_INSTALLDIR_VALID="1"</Publish>
<Publish Dialog="LogConfigDlg" Control="Back" Event="NewDialog" Value="InstallDirDlg"></Publish>
<Publish Dialog="LogConfigDlg" Control="Next" Event="NewDialog" Value="VerifyReadyDlg"></Publish>
在"InstallDirDlg"上，接下来我想做几件事。 首先是将输入到"LOGCONFIG_DIR"属性中的"路径"传递...
<Publish Dialog="InstallDirDlg" Control="Next" Event="DoAction" Value="SetLOGCONFIGDIR" Order="2">WIXUI_DONTVALIDATEPATH OR WIXUI_INSTALLDIR_VALID="1"</Publish>
<CustomAction Id="SetLOGCONFIGDIR" Property="LOGCONFIG_DIR" Value="[TESTSAVVY_SERVICES]" />
<!--Required for InstallDirDlg-->
<Property Id="WIXUI_INSTALLDIR" Value="TESTSAVVY_SERVICES" />
<!--Required for LogConfigDlg-->
<Property Id="LOGCONFIG_DIRECTORY" Value="LOGCONFIG_DIR" />
接下来是检查LOGCONFIG_DIR的注册表值，此逻辑完美运行。
<Publish Dialog="InstallDirDlg" Control="Next" Event="DoAction" Value="regSetLOGINSTALLDIR" Order="3">PREVIOUSLOGINSTALLFOLDER</Publish>
<CustomAction Id="regSetLOGINSTALLDIR" Property="LOGCONFIG_DIR" Value="[PREVIOUSLOGINSTALLFOLDER]" />
<Property Id="PREVIOUSLOGINSTALLFOLDER">
<RegistrySearch Id='LOGCONFIG_DIRRegSrch' Type='raw' Root='HKLM' Key='Software[Manufacturer][ProductName]' Name='LOGCONFIG_DIR' />
</Property>
最后导航到下一个对话窗口。 所以问题出在"发布 - 事件="DoAction"值="SetLOGCONFIGDIR"'上。 该目录不会反映用户在 InstallDirDlg 中输入的内容，除非用户按下"LogConfigDlg"中的"后退"按钮，然后在"InstallDirDlg"上第二次按"下一步"。
为什么用户第一次从"InstallDirDlg"按"下一步"时没有触发此操作，如上所述，用户必须返回该页面并再次按下一步？ 任何想法将不胜感激。
奇怪的是，另一个操作(设置方式几乎相同)在注册表项存在时工作正常。
更新
下面我在导航到下一个对话框窗口"LogConfigDlg"时包括日志部分。
当注册表项存在时记录("regSetLOGINSTALLDIR")，这有效...

如您所见，当注册表存在时，这两个操作都会被触发。 并且注册表项的覆盖正确发生。
问题是由"订单"属性创建的。 我很确定我的问题是由我使用 WiX 托管对话框窗口 (InstallDirDlg) 引起的。 修复最终将"SetLOGCONFIGDIR"事件的"订单"属性设置为"3"，下面是"下一个"的完整链的示例......
