($document.form.userNameContains.value) of '==' operation has null value. If a reference, it may not be in the context. Operation not possible. templates/allusers.vm [line 24, column 69]

As Ive said previously, you are mixing server side and client side concepts, velocity != javascript.

Prefixing a # indicates that it is a velocity directive, this runs on the server and dissapears by the time it gets to the client. What you are seeing as a server side validation failure, because $document cannot be resolved on the server.

Perhaps you could explain what you are trying to achieve? Where is this velocity triggered from, an action? Perhaps you are looking for the current user that is available (if driven by an action) via $action.getLoggedInUser(), then you can use the various methods on the user for your comparison.

Try #if($document.form.userNameContains.value.equals($element.getName()));

Also check if both the values are not null
