View Full Version : One value from jsonResponse missing on my Grid

19 Sep 2012, 12:35 AM
Hi there,

I have a grid with several columns and all of them show correctly the value except one that for some reason receives an undefined value, this is very weird and I have never seen it before.

I have created my own columns extending from Ext.grid.column.XXX (depending on the column) and it works perfectly for other values but not for this one, it just gets lost somewhere and I cannot find where, I have debugged since the request is thrown until the renderer but I am still not able to find where this value is lost, has someone seen something like this?

This is the definition of my column class:

extend : 'Ext.grid.column.Column',
alias : 'widget.bw-column',

constructor : function(c)
Ext.apply(this, c);

renderer : function(value, metaData, record, rowIndex, colIndex, store)
if (typeof value === 'undefined') return 'value is undefined!'; //just for the example
return BW.th.templates.plainText.apply({text: BW.exists(value.text) ? value.text : value});

This is the column as I generate it in my JSP:

"dataIndex": "implementationDate",
"enableResize": true,
"flex": 1,
"text": "Implementation date",
"hidden": false,
"isOperation": false,
"menuDisabled": false,
"showColumn": true,
"sortable": true,
"xtype": "bw-column",
"cls": "implementationDate "

Here you have a screenshot of my JSON response:


where you can see that the implementationDate is present, and this is the output of the grid:


Where you can see that for the "Implementation date" column the received value is undefined.

For all the other values I have no problem but this specific one is just missing.

Any idea of where my implementationDate value is would be highly appreciated :)

You should check the store to see whether or not it is populated with data from server. What do your model and store look like?

You pushed the correct button, Sir. I had a missconfiguration on the Model. Solved now :)

Thanks for your support!!
