[xwiki-devs] Two problems about wysiwyg

Hello , I an sorry it's also simple problems about wysiwyg. The first one .can I use component in wysiwyg plugin. (The component is to get and save data in database which is not the table created by XWIKI, and not mapped by hibernate )I hava used it ,but it can't run .So , I wander it is the problem in my code or XWIKI doesn't support it (I thinke there is something wront with the grammer .I don't know how to say it correctly ,but I think you can understand it). The second one is when I use js to operate the wysiwyg, I use editor.getRichTextArea().contentWindow.document.body to get the document ,but all the operate to the html do nothing to the source , and {{html}} tag which I think will work also take no effect. So ,If I append html child to the document ,The change can't be saved .Is there method to make it or the method to operate the source .I don't think getSourceText can achieve it .. Thank you!
