    Default Genius / Jedi guidance needed on A Coldfusion Grid Dilema

    Genius / Jedi guidance needed on A Coldfusion Grid Dilema


    Hope you're all well.

    Sorry to trouble you like this, but I was wondering if you could give me some advice on a problem which I simply can't iron out?

    The below code is for a Coldfusion 10 Ext 3.1 Grid. Using Firebug I can rule out any reported errors; clicking on the the console tab within Firebug I can see the returned query but it simply doesn't populate the Grid itself.

    Can you boys see what I'm doing wrong?

    All the best,

    I don't see anything wrong...


    Give your grid and ID (or just find the generated id), and in the fb console write Ext.getCmp('mygridid').getStore().data and confirm your store is populated with data. Is it?

    If it is, try simplifing your column config and record to only include one field or two. Drop the rowNumberer() (that might be actually a good place to start), and see if that helps. Then add the columns back in one by one. Basically just simplify things to help debugging.
