Trying To Get Property Of Non-Object

[ahmad_albab (Ahmadalbabxxx)]

hi guys…

may i know what does "Trying to get property of non-object" mean?

how and where can i look for the error?

thank you…

This means that you’re trying to access property of something, that is not an object.

For example, if you do something like this

$model = MyModel::model()->findByPk('non_existent_primary_key');

the $model will be null, so if you do

echo $model->id;

you’ll get this error.

Seems like the problem is somewhere here

C:\BitNami\wappstack-5.4.22-0\apache2\htdocs\yii\framework\zii\widgets\grid\CDataColumn.php(137): CComponent->evaluateExpression("$data->neg->neg_lawat", array("data" => Permohonan, "row" => 4))

I guess that your ‘neg’ relation is null sometimes (left join), so calling $data->neg->neg_lawat will cause this error.

Also i think that Permohonan must be either quoted or dollar-signed ($Permohonan), so check your XController.
