Google App Engine Go SDK update problems with template

I`ve just updated my GAE Go SDK to the newest release. I ran the gofix on my code, but there were still some errors. The code used to look:

   AnkietaTemp = template.New(nil)
   err := AnkietaTemp.ParseFile("ankieta/ankieta.html")

but now passing nil doesn't seem to work, so I replaced it into:

   AnkietaTemp = template.New("")
   _, err := AnkietaTemp.ParseFile("ankieta/ankieta.html")

Tried running my app, but in HTML source I get:

 <td width="400"><img src="images/{.section One}{@}{.end}"
alt="images/{.section One}{@}{.end}" width="100%"/></td>

Instead of a neat reference to an image file.

What is the proper way to parse the template files now, after the update?

In the new template package the template tag syntax changed, as you can see in the documentation. E.g. dot (.) is used instead of @ for referencing the "current" item and the template tags are indicated with two curly braces instead of one.

Edit: Oh, and there's no .section tag any more. You didn't provide the structure you pass to template's Execute() method so I can't provide details on how mitigate that exactly, but I guess you can use {{with}} tag like {{with One}}{.}{{end}} or maybe {{.One}}.
