def above(that: Element): Element = {
val this1 = this widen that.width
val that1 = that widen this.width
elem(this1.contents ++ that1.contents)
}
Note line 2 and 3:
val this1 = this widen th...

The problem is, the new librar...

I'd like to embed a link to a secure page of my application in one of my unsecure pages.
The secure tomcat port is configured in the server.xml file. In some deployments it's 443, 8443 etc.

Alternatively, simply getting acc...
