Introduction:
This describes best practices when changing icons or customizing the service catalog UI.
Failing to properly maintain customized files can cause problems such as missing buttons and links or more serious issues in the UI.
Instructions:
If you are going to customize the service catalog UI, remember to always first copy the file you want to customize from it's location under:
%USM_HOME%\view\webapps\usm
to the equivalent location in:
%USM_HOME%\filestore\custom
Then customize the files from the custom folder. These files will take precedence over the files in the normal path.
However, it is very very important that:
1) After you apply any patch, you review the list of files that are updated, and displayed by the patch, and then if you have customized any of those files in your filestore you will need to copy the new file from the patch and make similar custom changes to this new file.
2) If you upgrade, then again you will need to add your customizations to the new files for your new version. You should never copy custom files over from an older version of the product
