Steps to reproduce: 1. Create a new XHTML document; 2. Go to the source view and paste the following snippet into the "body" tag: <applet height="100px" width="100px"><param name="foo" value="bar" />Fallback content</applet> <p>Type something here</p> 3. Go to WYSIWYG view and type something into the paragraph that follows the applet tag; 4. Change to source view again (or just save the document). Expected results: Modifying any content within the page (step 3) would be harmless. Actual results: Modifying the paragraph that follows (step 3) and switching to source view (step 4) breaks the applet tag completely: <param name="foo" value="bar" /> <p>Fallback content <p>Type something herex</p> This kind of breaking affect the whole document also, which is serious. Additional information: The problem seems to be triggered by including the "param" element. A standalone "applet" element is left untouched. The problem is seen in HTML documents as well, just use the HTML way of closing empty elements. This was originally reported by Francesco [1], later confirmed/clarified by Chaals [2]. My environment is: * Amaya 11.3.1 (Dec 9 2009), VC9 flavor; * Windows Vista SP2. Workarounds: A potentially plausible workaround can be using other tags [3] to include Java applications: "object" (standard) or "embed" (supported in most browsers). A quick test performed with "object" elements shows that it doesn't seem to trigger the same behavior.

The red button in the lower right corner is lit. If you click it, you get an error message explaining the problem. 2 - If the document does not use this DTD (it uses for instance HTML 4.01 or XHTML 1.0 Transitional), then the <applet> element is allowed. But there was a bug in Amaya: the <param> elements included in an <applet> element were moved by the parser outside of the <applet>. This bug is fixed: the <param> elements stay now within the <applet>. Vincent.
