Ejuicombobox Throwing Undefined Offset Error On Specific Model Attributes - autocomplete

Question

I downloaded the Editable combo box control with Auto-complete and added the extension. I am having problem with patient_id and problem_definition_id attributes of the model. Works fine for problem_duration_id and some other attributes. When I use them for the combo box I receive the following error:
Following is the code that i have used in my view:
$this->widget('ext.combobox.EJuiComboBox', array(
'model' => $PatientProblem,
'attribute' => 'problem_definition_id',
'id'=>'eeed',
'data'=>Yii::app()->cache->get('PATIENT_PROBLEM'),
// options passed to plugin
'assoc'=>true,
'options' => array(
'allowText' => false,),
// Options passed to the text input
'htmlOptions' => array('size' => 6),
));
Following is the my model:
<?php
/**
* This is the model class for table "patient_problem".
*
* The followings are the available columns in table 'patient_problem':
* #property integer $problem_id
* #property integer $problem_definition_id

Any help would greatly appreciated.

Answer 1

I used to have the same error for EJuiComboBox, too. It happens whenever NO DATA is found to feed the Textfield in the combobox, it is a PHP Error.. I made the following change to the run method of EJuiComboBox to stop it from throwing this PHP error when no data is found
public function run()
{
list($name, $id) = $this->resolveNameID();
if (is_array($this->data) && !empty($this->data)){
//if $data is not an assoc array make each value its key
$data=($this->assoc)?$this->data:array_combine($this->data, $this->data);
//does the same as array_unshift($data,null) but does not break assoc arrays
$data=array(""=>"")+$data;
}
else
$data = array();
if ($data == array()) {
echo "No hay registros";
return;
}
if ($this->hasModel())
echo CHtml::activeDropDownList($this->model,$this->attribute,$data,$this->selectHtmlOptions);
else
echo CHtml::dropDownList($name, $this->value, $data,$this->selectHtmlOptions);
echo CHtml::textField(null,($this->hasModel()?($data[$this->model->{$this->attribute}]):$data[$this->value]),array('id'=>$id.'_combobox'));
$this->options = array_merge($this->defaultOptions, $this->options);
$options = CJavaScript::encode($this->options);
$cs = Yii::app()->getClientScript();
$js = "combobox({$options});";
list($id, $js) = $this->setSelector($id.'_combobox', $js);
$cs->registerScript(__CLASS__ . '#' . $id, $js);
}
Using this method will result in a simple rendering of "No data found!" whenever there are No members in the data for the ComboBox.

Answer 2

I solved the problem. By default, Yii gets the Not Null attribute of a column during runtime from the database, so if a column is marked as Not Null in database, it applies zero (0) as its default value. When "$this->model->{$this->attribute}" was getting executed, it was putting "0" instead of "problem_definition_id" which was throwing error. After making the column to Nullable in database, the error vanished. But since this does not seem a good solution. So after I created the $PatientProblem object, I explicitly set the problem_definition_id to null and it resolved the error.
