Hello Thiago,
Well, in Tapestry 5.0.6, if you just add a column using BeanModel.add,
it doesn't show any label, unless you have a <added column name>-label
entry in your app.properties.
Don't even have such a property file, but yes - it shows a label (just
tried it again to make sure). In your example down there it would be
"action".
beanModel.add("action", null).label("any label you want, including an
empty string.");
Like I said, when I try "giving null, an empty string or a whitespace
results in a tapestry exception stating "Parameter label was null or
contained only whitespace"".
I've posted a related JIRA,
https://issues.apache.org/jira/browse/TAPESTRY-1983, asking for a new
parameter in Grid to add new columns without the need to create a
BeanModel explicitly as we have to do now.
Ah, great! Just added a comment that this would be useful for
BeanEditForm too - and voted for it. :)
