After a clean install, following a number of dead ends i have mnaged to isolate what appears to either be a bug or something hidden somewhere that needs to be turned off or removed.
I haev set up SilverStripe 2.3.0-rc2 with blog and forum, i was hoping to be able to embed the occasional object such as a flash movie into the blogs and on the main site but it appears that even if you manually edit the HTML via the admin interface an object such as this.
<object width="550" height="400">
<param name="movie" value="/assets/flash/evil-icon.swf">
<embed src="/assets/flash/evil-icon.swf" width="550" height="400">
seems to get filtered and both the
<param.....> tag and <embed...>
I have updated tiny_mce_improvements.js and tinymce.template.js but this did not seem to resolve the problem.
However if i deleted the object from the page i could then sage the page.
Im not an expert but it seems to me that upon saving the information it is being run past a filter. any pointers would be appreciated as to either how to fix this or where to start looking. I would say from what i have seen that once this is resolved then it should also fix the problem with using the GUI to add/embed flash items.
