Have you ever tried to assign a custom master page to the system pages in SharePoint?
This is what I used to do up to now.
Create a feature that deploys the master pages.
add in the onet.xml to the configuration with id 0 the following two lines:
MasterUrl=~SiteCollection/_catalogs/masterpage/My.master
CustomMasterUrl=”~SiteCollection/_catalogs/masterpage/My.master”
Deploy the solution.
Check that the masterpages are there and that they are used by the site created using my template template … Only the default master page is set but the system master page isn’t set.
I then had a look at the following page
http://msdn.microsoft.com/en-us/library/bb687712.aspx
What did I do wrong?
I created my module within a feature.
instead of adding the following to my onet.xml.
[code lang=text]
<Module Name=”MyMasterPages” Url=”_catalogs/masterpage”>
<File Url=”My.master” Type=”GhostableInLibrary”>
</File>
</Module>
[/code]
So what went wrong then?
It’s all about the order that things get activated. I was creating the master page after the site was created using my site collection feature.
Adding the master page using a module in the onet.xml resolved this issue.
