If HTML page loaded through portal access includes <a> HTML element without 'href' attribute defined, then explicit execution of 'click()' method for this element leads to defining of an empty 'href' attribute. This may imply re-loading of current HTML page or loading new page with base URL if it is defined.


Current HTML page may be re-loaded accidentally or replaced by another one.


HTML page loaded through portal access with the described conditions.


It is possible to replace click() method calls by explicit execution of the same code as defined in 'onclick' attribute of appropriate <a> element.

Fix Information
