    Unable to create forms / no document tree on 4.4.0

    Hey all,

    I'm unable to get a new install of forms to work. The installer works fine, but when I click into the Forms section of the backend I get an immediate error.

    Consequently, the 'Welcome to Forms' overlay shows up and I can actually click on the "Create a Form!" button to make my first form. After that, though, with no left-tree to use to navigate, I am unable to do anything else.

    Any help would be greatly appreciated. I am using Umbraco 7.4.3 and installed Forms 4.4 manually via the ZIP file.

    Hi Leo and welcome to our :-),

    Sorry to hear that you have issues with Umbraco Forms. One thing to check when you say that you have no left-tree to use to navigate.

    Can you please check how your tree.config in the /config folder looks like the check that you have these added. 

    <add initialize="true" sortOrder="2" alias="datasource" application="forms" title="Datasources" iconClosed="icon-folder" iconOpen="icon-folder-open" type="Umbraco.Forms.Web.Trees.DataSourceTreeController, Umbraco.Forms.Web" />
<add initialize="true" sortOrder="0" alias="form" application="forms" title="Forms" iconClosed="icon-folder" iconOpen="icon-folder-open" type="Umbraco.Forms.Web.Trees.FormTreeController, Umbraco.Forms.Web" />
<add initialize="true" sortOrder="3" alias="prevaluesource" application="forms" title="Prevalue sources" iconClosed="icon-folder" iconOpen="icon-folder-open" type="Umbraco.Forms.Web.Trees.PreValueSourceTreeController, Umbraco.Forms.Web" />
<add initialize="true" sortOrder="3" alias="formsecurity" application="users" title="Forms Security" iconClosed="icon-folder" iconOpen="icon-folder-open" type="Umbraco.Forms.Web.Trees.FormSecurityTreeController, Umbraco.Forms.Web" />

    Hope this helps,

    /Dennis

    All of those entries are present in trees.config and seem to be in order.

    A few more things I've tried/discovered since. The users section is similarly affected, as soon as I try to access either it or the forms section I get that error pane, but any other section remains accessible and fine.

    We bought a license anyway thinking maybe it was a licensing issue and are still seeing this error. Not sure where to start, I can't seem to get visual studio to debug on anything. This is a real show stopper, any troubleshooting suggestions would be very much appreciated.

    This is the error pane

    I think I managed to fix this, and it seems like an enormous gotcha to not have documented anywhere.

    I'm using dependency injection for my application so I had to add this (using AutoFac since thats what the original documentation had examples for and suggestions)

     builder.RegisterApiControllers(typeof(Umbraco.Forms.Web.Controllers.UmbracoFormsController).Assembly);
builder.RegisterControllers(typeof(Umbraco.Forms.Web.Controllers.UmbracoFormsController).Assembly);

    Luckily Forms is available on Nuget, something I don't think I saw mentioned anywhere else(?) so I didn't have to do any weird shenanigans with adding it as a reference.

    This makes everything load now, If there's any other issues or gotchas i'll report back.
