tinymce_hammer can't save link

Hi, guys. I created a new a Rails 3 program to test tinymce with
tinymce_hammer gem. I was able to save bold font, bulleted-list format,
etc in the database and display it on the page except the "insert link".
On the edit page, I could insert the link to the highlighted text and
even open the link in new tab/window by clicking the highlighted text.
However, after I saved it, the highlighted text became plain text and
the inserted link on it was gone.
I am using tinymce_hammer 0.2.2 and tinymce 3.5 Jquery package.
Thanks in advance.

This plugin looks outdated.

Try to use this one

And remember to use the html_safe method to show the content, otherwise rails will not display as html.
