While trying to port an existing application from 2.7.7 to Lift-2.0-scala280-SNAPSHOT I discovered a issue where elements containing ajaxInvoke is not rendered when using setHtml in Comet.

When invoking the following partial update nothing seems to happen:

partialUpdate(SetHtml("field", <input type="button" onclick={ajaxInvoke(() => JsRaw("alert('hi')"))._2} value="Say hi"/ >))

This works as expected however:

partialUpdate(SetHtml("field", a(() => JsRaw("alert('hi')"), <span>Link</span>)))

Link to example application:
git://github.com/tbje/Lift-2.0-scala280-SNAPSHOT-issue.git

The application compiles and runs as expected by editing pom.xml by replacing

  <scala.version>2.8.0.Beta1</scala.version> 
  <lift.version>2.0-scala280-SNAPSHOT</lift.version>

with

  <scala.version>2.7.7</scala.version> 
  <lift.version>2.0-SNAPSHOT</lift.version>
