Subject: RE: [xsl] Infinite Loop when trying to use String-Replace From: "Ivan Pedruzzi" <ivan@xxxxxxxxxxxxxxx> Date: Wed, 31 Oct 2001 22:12:06 -0500 |
Hi Jeff, Stylus Studio detects possible infinite loop when the same template has been invoked more then one time with the same parameters. This is a warning and not an error, If you want you can turn it off (Tools->Options->XSLT Editor->XSLT Settings). The infinite loop detection avoid to hang the processor compare to other applications that freeze forever.
