Custom Master page set as a default on feature activation in Moss

Question

I've a site in moss. I have created feature in my solution and on feature activation it will set the custom master page
CustomMaster.master as a default master page and on feature deactivation it will set as a default master page
default.master.
The problem I'm facing is that if I'm activation the feature at first time then it will set the CustomMaster.master as a default master page but when I'm deactivate the feature it will remove the
CustomMaster.master page and module. but when I'm again activate feature at that time it will not create mo1dule and CustomMaster.master in "_catalogs/masterpage/". So, no error was given on feature activation but
it will give error while I'm accessing my site as a "File Not Found" because
CustomMaster.master is not created.
Code of Module.xml file
<Module Name="Master" Url="_catalogs/masterpage"> <File Path="Master\CustomMaster.master" Url="Master/CustomMaster.master" IgnoreIfAlreadyExists="TRUE" Type="GhostableInLibrary"/> </Module>
Code of method which is call on feature activation
public void SetCustomMasterPage(SPFeatureReceiverProperties properties, string MasterPageName)
try
#region SetMasterpage
SPSite siteCollection = properties.Feature.Parent as SPSite;
if (siteCollection != null)
foreach (SPWeb web in siteCollection.AllWebs)
// Get the Site Collection root path to get the master page gallery.
string siteCollectionRoot = web.Site.RootWeb.Url;
// Set the Site Master to Custom.master
var siteMaster = new Uri(siteCollectionRoot + "/_catalogs/masterpage/Master/" + MasterPageName);
web.CustomMasterUrl = siteMaster.AbsolutePath;
web.MasterUrl = siteMaster.AbsolutePath;
// Clear the Alternate CSS
web.AlternateCssUrl = string.Empty;
// Save the changes back to the web
web.Update();
#endregion
catch (Exception)
Code of methods which are call on feature deactivation
public void SetDefaultMaster(SPFeatureReceiverProperties properties)
try
SPSite siteCollection = properties.Feature.Parent as SPSite;
if (siteCollection != null)
foreach (SPWeb web in siteCollection.AllWebs)
// Get the Site Collection root path to get the master page gallery.
string siteCollectionRoot = web.Site.RootWeb.Url;
// Set the Site Master to Custom.master
var siteMaster = new Uri(siteCollectionRoot + "/_catalogs/masterpage/default.master");
web.CustomMasterUrl = siteMaster.AbsolutePath;
web.MasterUrl = siteMaster.AbsolutePath;
// Clear the Alternate CSS
web.AlternateCssUrl = string.Empty;
// Save the changes back to the web
web.Update();
catch (Exception)
public void RemoveCustomMasterPage(SPFeatureReceiverProperties properties, string MasterPageName)
try
using (SPSite sitecollection = (SPSite)properties.Feature.Parent)
using (SPWeb web = sitecollection.RootWeb)
string WebAppRelativePath = sitecollection.ServerRelativeUrl;
if (!WebAppRelativePath.EndsWith("/"))
foreach (SPWeb site in sitecollection.AllWebs)
WebAppRelativePath = site.Url;
if (!WebAppRelativePath.EndsWith("/"))
WebAppRelativePath += "/";
String MasterUrl = WebAppRelativePath + "_catalogs/masterpage/Master/" + MasterPageName;
SPFile fileUrl1 = site.GetFile(MasterUrl);
if (fileUrl1 != null)
SPFolder folder = fileUrl1.ParentFolder;
fileUrl1.Delete();
web.Update();
//attempt to delete the folder if it is now empty
if (folder.Files.Count < 1)
folder.Delete();
catch (Exception)

Hello Sameer,
When you are calling "RemoveCustomMasterPage" function?
Also make below change in web.config file your web application to know the problem:
1. Open up your sites web.config, and make the standard custom errors edit. You want it to be < customerrors mode="Off"/>
2. Then, search for the CallStack="false" and change it to CallStack="true", you should find this in the "<safemode>" node.
3. Find:   <compilation debug="false" />, Replace with: <compilation debug="true" />
