Details

The following example works on NS6.X and NS7.X and MOZ1.1. In javascript one way to write "back" to the plugin is to use the following code: document.frm2.open("text/html"); document.frm2.write("Hello World"); document.frm2.close(); To do this one needs 2 frames in a window. One holds the javascript, the other window is written into. The code above when executed will dynamically write "Hello World" in the second frame using HTML from javascript in the first frame. I have attempted to perform the same write to my "custom" plugin with no success on MOZ1.1 and NS7.X. This works on NS4.7 using W2K. I am hoping that this is a configuration problem and not yet another loss of functionality per new standards. The obvious question would be why would "built-in" plugins have this capability but custom plugins not. If this is indeed a bug I will send attachments that can reproduce the bug. I am using the legacy plugin model. I have developed other plugins for mimetypes, such as myDoc.xyz, that get launched by clicking on the doucment. They work fine for MOZ1.1.
LiveConnect which was used in 4.x browsers to script plugins from JavaScript is not supported in Mozilla. To retain scripting functionality the plugin needs to be changed to adopt XPConnect mechanism. Please refer to the articles we have mozilla.org/projects/plugins. If you feel this is not correct resolution please reopen and explain.
