HTTP Error 404 when creating a custom field that contains a variable

*SYMPTOMS:
In Report Designer, when a variable is inserted in a custom field and not yet created, the following message displays:

" A variable is still undefined. Do you want to define it now ?"

After clicking on Yes, the dialog for creating the variable opens. For some expressions, this dialog window displays the following error message :

ERROR:
"The page cannot be found
The page you are looking for might have been removed, had its name changed, or is temporarily unavailable.
HTTP Error 404 - File or directory not found"


*REASON:
This error message may occur when the expression used to defined the custom field contains certain characters that security tools such as "URLScan" blocks (for instance, the character "<" with URLScan 3.1).
This is occurring because the page URL contains the expression of the custom field, including the blocked character.

*WORKAROUND:
Define the variable before using it in the custom field expression.
