PortalSiteMapProvider was unable to fetch children for node at URL: message: Object reference not set to an instance of an object

I was seeing this error the other day on our test publishing site, and tracked it down to an issue in the web.config file.  Seems like our web.config was using the wrong default provider:

<siteMap defaultProvider="CurrentNavSiteMapProvider" enabled="true">

where it should have been to set to:

<siteMap defaultProvider="CurrentNavigation" enabled="true">

EditModePanel Hiding Content in SharePoint 2010

It appears that the functionality of the EditModePanel has changed subtly in SharePoint 2010.  When using PageDisplayMode="Display", like this:

<PublishingWebControls:EditModePanel runat="server" CssClass="editpanel" PageDisplayMode="Display" ID="editmodepanel1">
lorem ipsum dum dolor
</PublishingWebControls:EditModePanel>

in 2007 the content would show to all  users when the publishing page is in display mode.  In 2010, the content will only show to users that have permission to edit the page.  A subtle change to be aware of.

Stapler feature GLOBAL#0 doesn't staple

When adding feature staplers, you can add individual site templates to activate the feature staplee like so:


<FeatureSiteTemplateAssociation Id="c9a041c2-f258-4290-bfa9-96c854a12b24" TemplateName="SPSNEWS#0"/>

where the ID is the Staplee feature ID, and the TemplateName is the [WebTemplate Name]#[Web Template ID].

But when trying to associate ALL site templates, you've got to drop the #[Web Template ID] to get it to work, like this:

<FeatureSiteTemplateAssociation Id="c9a041c2-f258-4290-bfa9-96c854a12b24" TemplateName="GLOBAL"/>
