Hey, Im trying to install an own-made package but when installing I run into the following null reference exception:
At
/umbraco/developer/packages/installer.aspx?installing=businesslogic&dir=D:\Inetpub\umbraco%20(test%20package%20installations)\data\ddc1f406-98b6-42ca-b2e3-060ae1a3e536&pId=6 (Referred by: http://localhost/umbraco/developer/packages/installer.aspx): System.NullReferenceException: Object reference notsetto an instance of an object. at umbraco.cms.businesslogic.web.Document.Import(Int32 ParentId,User Creator, XmlElement Source) at umbraco.cms.businesslogic.web.Document.Import(Int32 ParentId,User Creator, XmlElement Source) at umbraco.cms.businesslogic.web.Document.Import(Int32 ParentId,User Creator, XmlElement Source) at umbraco.cms.businesslogic.web.Document.Import(Int32 ParentId,User Creator, XmlElement Source) at umbraco.cms.businesslogic.packager.Installer.InstallBusinessLogic(Int32 packageId, String tempDir) at umbraco.presentation.developer.packages.Installer.processInstall(String currentStep) at umbraco.presentation.developer.packages.Installer.Page_Load(Object sender, EventArgs e) at System.Web.Util.CalliHelper.EventArgFunctionCaller(IntPtr fp, Object o, Object t, EventArgs e) at System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) at System.Web.UI.Control.OnLoad(EventArgs e) at umbraco.BasePages.BasePage.OnLoad(EventArgs e) at System.Web.UI.Control.LoadRecursive() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint
)
I cannot figure out what the issue is but it seems to be just before the package actions are fired since the actions are not done. However the problem does not lie in the actions since i have tried removing all actions and installing the package with the same result.
The reason for this error was that I had missed installing another package beforehand which contained a datatype that the second package needed. So my bad, and you can close/delete this topic.
One suggestion for future Umbraco versions is to have more detailed error messages for package install problems, or for the logging of the errors. Have had problems with package installs alot and the really difficult part is that the errors are so cryptic.

Any clues or tips would be much appreciated!
