Module would not save HTML tags in the Alternative content parameter field

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Enter text   test<br />  in Alternative content parameter field and click 
Apply

What is the expected output? What do you see instead?
I expected test<br /> to be saved.  Instead the text  test  is save and the <br 
/> is stripped out.

What version of the product are you using? On what operating system?
Joomla 1.6.1 / mod_swfobject_v2.1

Please provide any additional information below.
I fixed it for me by updating modules\mod_swfobjext\mod_swfobject.xml, 
add parameter, filter="safehtml", to alt_content
eg
        <field name="alt_content" type="textarea" cols="35" rows="10" default="" label="Alternative content" description="HTML to display if flash player is not detected." filter="safehtml" />

Maybe Joomla 1.6 specific, also another setting might be filter="raw" (?)   

Thanks for a great Module.
Hope this helps.
Bryn

Had to comment-out the line <p><?php echo JText::_('Requirements');?></p> in 
tmp/default.php as well.

I also had to remove the line <p><?php echo JText::_('Requirements');?></p> in 
tmp/default.php as well. Otherwise you get the text "Requirements" displayed 
below your  NON-HTML version of the module.

I also have the same issue in Joomla 1.7.
The Alternative content box is stripping all content contained within valid 
HTML tags and leaving only text.

I had this issue in joomla 2.5 as well, the OP's fix worked like a charm.

And thanks for the really handy module!

Updating modules\mod_swfobjext\mod_swfobject.xml worked for me, too. Using 
Joomla 2.5.6
Didn't need to edit tmpl/default.php.

That's saved me hours of trying to figure out what's going on. THANK YOU!
