[Catalyst] Jason Kohles' tutorial on ExtJs editable data gridsandCatalyst

[jagdish eashwar]

Hi,
I ran into some trouble while trying to extend Jason Kohle's tutorial from
a  one-table database to a two-table database.

The tutorial had a people table with the following columns: id, name, and
affiliation. I altered the affiliation column into an affiliation_code
column. And then I created another table called affiliation to hold the
affiliation_code and the affiliation_description. I also specified that the
affiliation_code column in the people table was a foreign key which
referenced the affiliation table's primary key.
I then recreated the Model in the Catalyst Application. So now the people
table had a 'belongs to' relationship with the affiliation table.

With this arrangement, I am able to populate the grid with data from the
affiliation table, but Catalyst throws up an error when I try to populate
the grid with data from the people table.
The error I get is :
"[error] Caught exception in AdventAjaxGrid2::View::JSON->process
"encountered object
'AdventAjaxGrid2::Model::AdventAjaxGrid2DB::Affiliation=3DHASH(0x91b8270)',
but neither allow_blessed nor convert_blessed settings are enabled at
/usr/local/share/perl/5.8.8/JSON/Any.pm line 426."

I couldn't figure out how to enable those settings from the JSON-Any write
up on CPAN. How is that to be done?
