I started looking into overcoming this. Obviously, there is a fairly straight-forward approach - modify the application.master. Ouch. Then, any changes to design in one file have to be replicated elsewhere, with one file in the Master Page Gallery, and one on the file system.

Alternatively, I found a neat solution at David’s blog. This uses an HTTP Module to reset the master page for any pages looking for application.master.

But after following his instructions, my admin pages wouldn’t work. I just got the error page ‘Unknown Error’.

Digging into the logs, I found what was going on - there were 2 content placeholders that the application.master uses which weren’t on my ‘normal’ master page. Make sure you add place holders for:

<asp:ContentPlaceHolder id="PlaceHolderPageDescriptionRowAttr" runat="server"/>
<asp:ContentPlaceHolder id="PlaceHolderPageDescriptionRowAttr2" runat="server"/>

The full list of placeholders used in both files is:

• PlaceHolderPageTitle
• PlaceHolderAdditionalPageHead
• PlaceHolderBodyAreaClass
• PlaceHolderBodyLeftBorder
• PlaceHolderBodyRightMargin
• PlaceHolderCalendarNavigator
• PlaceHolderFormDigest
• PlaceHolderGlobalNavigation
• PlaceHolderGlobalNavigationSiteMap
• PlaceHolderLeftActions
• PlaceHolderLeftNavBar
• PlaceHolderLeftNavBarBorder
• PlaceHolderLeftNavBarDataSource
• PlaceHolderLeftNavBarTop
• PlaceHolderMain
• PlaceHolderMiniConsole
• PlaceHolderNavSpacer
• PlaceHolderPageDescription
• PlaceHolderPageImage
• PlaceHolderPageTitleInTitleArea
• PlaceHolderSearchArea
• PlaceHolderSiteName
• PlaceHolderTitleAreaClass
• PlaceHolderTitleAreaSeparator
• PlaceHolderTitleBreadcrumb
• PlaceHolderTitleLeftBorder
• PlaceHolderTitleRightMargin
• PlaceHolderTopNavBar
• PlaceHolderUtilityContent
• SPNavigation
• WSSDesignConsole
• PlaceHolderHorizontalNav Normal master page only
• PlaceHolderPageDescriptionRowAttr Admin master page only
• PlaceHolderPageDescriptionRowAttr2 Admin master page only

For example, using a StringBuilder to create my CAML query (for my SPQuery object), this might look like:

caml.Append("<Leq>");
caml.Append("<FieldRef Name='MyDueDate'/>");
caml.Append("<Value Type='DateTime'>");
caml.Append(System.DateTime.Today.ToString("u"));
caml.Append("</Value>");
caml.Append("</Leq>");

(This query contains the date contained in the MyDueDate column with the current date and time).

Part I, Part II, Part III

(For content accessible to employees/partners only, I presume it’d be a normal client access license).

Update: See the Logical Architecture Model: Corporate Deployment document for details on this, and dealing with partners. That’s quite interesting - you can host partners sites on Internet or Intranet farms.

Given that you can do all of what you do with Master Pages it does make me wonder - what are Themes for?

Updated: Heather Solomon has looked at it, and her suggestion is to just put your styles in the Master page.

Don’t forget to add into the System.Workflow.ComponentModel.WorkflowCompiler section of the web.config file.

Repeating fields in Infopath forms are unusable. Nobody knows how to do this. I spent ages working on it, but I didn’t get anywhere. I couldn’t write to these properties through the task properties at all. Indeed, the whole TaskChangedProperties.ExtendedProperties hash is daft. Forcing everything to flatten, well, sucks. Can’t I have a stream? Or a node-child tree of some sort? I mean, is it surprising to want to send InfoPath forms to/from a workflow task and a library? You know, use the workflow for routing, and the xml form in a library as the data store? That should be easy - it’s not.

Debugging workflows is hard. I mean, apart from Visual Studio crashing as I connect it to the appropriate service, there is a question over actually being able to get meaningful error messages out of workflow, and getting it able to breakpoint in the right places. In fairness, this is a complex thing. I have no idea how I’d set about allowing debugging in Visual Studio, say, after a Delay activity had expired. But it would be cool to have something a bit better.
