Catalyst Action REST - ExtJS TreeLoader

Catalyst doesn't play with ExtJS TreeLoader by default as the View::JSON returns hashes of JSON data, ExtJS TreeLoader requires an array. However you can setup View::JSON to expose a set hash key only, therefore only the array is returned.

Note that on existing stashes you will need to pre-pend the existing key with an addition key 'json' to ensure existing functionality works.

Catalyst Controller

$c->stash->{json} = \@nodes; #array of treeloader data


Catalyst Application lib/app.pm


__PACKAGE__->config(
'View::JSON' => {
expose_stash => 'json', #extjs TreeLoader requires an array of data
}
);
