Hi,
I develop a new application in sencha JS 4.0 with a CRUD interface.
I have a problem with forms (set checkbox value from a dataStore loaded from a sql/php backend)
As I didn't manage to get a form.panel working, I used a grid.panel. I was able to use a CRUD API to GET/PUT data from/to the PHP backend

I would like to use checkbox in a new tab of my application
- I know the number of checkbox
- I can load a dataStore from a json formated file (as a copy of data from the database)
- Checkbox are not checked ...

Of course, the goal is to update a database depending of what you check.

Many people did it by create dynamic checkox object. Should I do it that way ?

Thank you very much
Could you tell me where is wrong ?
Json file : action.json

{
'success': true,
'data': [
{'dID': '1', 'aID': '1', 'action':'on', 'value':true},
{'dID': '1', 'aID': '2', 'action':'off', 'value':true},
{'dID': '1', 'aID': '3', 'action':'dimmer', 'value':false}
]
}

},{

After the form has been created, try setting the values of the checkboxes:


Ext.getCmp('checkboxID').setValue(value);
