[Building Sakai] html links in announcements and T&Q

[Fischbein, Scott A.]

Karen and Steve - thanks for your help with this.

I tracked down the source of our problem - somehow, our "formattedtext.properties" file contained entries surrounded by quotes. So, for instance, we had: 

goodTags = "a,abbr,acronym,address,b,big,blockquote,br,center,cite..."

instead of 

goodTags = a,abbr,acronym,address,b,big,blockquote,br,center,cite...

So the parser was presumably including the quote along with the <a> and therefore not accepting <a> tags, but all the others were working.

I have no idea how we ended up with the quotes in there in the first place (we're running 2.7.0, and I double checked the Sakai SVN version and it doesn't contain the quotes), but now that they're removed, everything is working as expected.

Thanks again for the help.

Hi Chris,

Announcements certainly does support HTML links, confirmed on the nightly trunk, what version Sakai are you using?

cheers,
Steve

If it's an FCK field, you can either use the Insert/Edit Link icon or just type something like <a href="http://google.com" target="_blank">google.com</a> under source mode.
