Fwd: QName::=(NCName':')?NCName error when tml is parsed

[Jens Breitenstein]

Hi Andi, hi Kristian!

We solved the puzzle several days ago, but unfortunately the mail never 
appeared in the mailing list even my phone tells me it is sent :-(

See below

Thanks Jens

It looks like the library mapping name is causing this effect: in 
case the name begins with a digit as first character like "1st" 
component rendering fails. Using "first" instead fixes the problem 
and everything works as expected.

To me it looks like bug, but if it is expected behaviour I would 
prefer an "Illegal libray mapping name" exception. What do you think?

Hi T5 Users!

I am struggling with an strange error in T5.3.7 and hopefully one of 
you can give me a hint how to track it down..

I wrote a "Icon" component to show bootstrap glyphicons:

public class Icon
{
  @Parameter(required = true, defaultPrefix = BindingConstants.LITERAL)
  @Property private String _name;

  boolean beginRender(final MarkupWriter writer)
  {
      // <span class="glyphicon glyphicon-log-in"/>
      writer.element("span", "class", "glyphicon glyphicon-" + _name);
      writer.end();
      return true;
  }
}


So it's possible to show a glyphicon in a page by

<t:Icon name="exclamation-sign"/>

Everthing worked fine until I moved to component to a "common 
library package". After starting Jetty and accessing a page which 
uses this component I get:

Caused by: org.apache.tapestry5.ioc.internal.util.TapestryException:

Even more confusing is the fact the error never appears again it 
only occurs on first access.


Thanks in advance
