[html-formfu] ExtJS - metaData - Grid population via REST

I pretty new to ExtJS and the Catalyst controller, so forgive me if I 
have missed the blindingly obvious.

Basically I have a grid with gets filled dynamically from a Json store 
thanks to CatalystX::ExtJS and HTML::FormFu::ExtJS.

It seems to work well, except for when I try to use the ExtJS handler 
'metachange' to dynamically set the column headers. It would seem this 
is due the fact that the 'header' key is missing from the metaData 
supplied via the Json store.

I can fix this with the following patch to _Field.pm

+               header  => $self->label,
          type    => "string",

I know this is a hack, but wanted to post here to see if there is a 
better way ... what might the knock on effects might be?  .. anyone else 
had this problem?.. etc. etc.

Many thanks
