New 3.9.1 textbox parameter

I'm interested in using the new textbox parameter for some of my text data elements. When I add the parameter, it does not influence the form screen:

I have the following in my Form-Template:

<dt><label for="jform_to">To</label></dt>
<dd>{joodb form|to|textbox}</dd>


But the resulting form continues to be the standard text editor.

Hello Chip,

sorry but the parameter is textarea not textbox.
I have to fix this in the documentation.
