It’'s model validation rules issue
Please read this I hope it may be some help.
Ok this is my _form.php
<?php
/* @var $this IssueController */
/* @var $model Issue */
/* @var $form CActiveForm */
?>
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'issue-form',
'enableAjaxValidation'=>FALSE,
)); ?>
<?php echo $form->errorSummary($model); ?>
<?php echo $form->labelEx($model,'Title',array('class'=>'control-label')); ?>
<?php echo $form->textField($model,'Title',array('size'=>25,'maxlength'=>25)); ?>
<?php echo $form->error($model,'Title'); ?>
<?php echo $form->labelEx($model,'ProjectId',array('class'=>'control-label')); ?>
<?php echo $form->DropDownList($model, 'ProjectId',CHtml::listData(Project::model()->findAll(), 'Id', 'Name'),
array(
'ajax' => array(
'type'=>'POST', //request type
'update'=>'#Issue_ProjectVersionId', //selector to be updated-drowdown to update
'data'=>array('ProjectId'=>'js:this.value','YII_CSRF_TOKEN' => Yii::app()->request->csrfToken), //'data'=>'js:javascript st
//atement' any other data like CSRF tocken to be passed
//if commentd all things will be passed
'url'=>CController::createUrl('ProjectVersion'), //url to call.i.e controller's-action to
),
'empty'=>'Select Project'
));?>
<?php echo $form->error($model,'ProjectId'); ?>
<?php echo $form->labelEx($model,'ProjectVersion',array('class'=>'control-label')); ?>
<?php echo $form->DropDownList($model, 'ProjectVersionId', array('value'=>isset($model->projectVersion->VersionName) ? $model->projectVersion->VersionName : "Select Version")); ?>
<?php echo $form->error($model,'ProjectVersion'); ?>
<?php echo $form->labelEx($model,'BrowserId',array('class'=>'control-label')); ?>
<?php echo $form->dropDownList($model,'BrowserId' , CHtml::listData(Browser::model()->findAll(), 'Id', 'Name'),
array('ajax' => array(
'type'=>'POST', //request type
'update'=>'#Issue_BrowserVersionId', //selector to be updated-drowdown to update
'data'=>array('BrowserId'=>'js:this.value','YII_CSRF_TOKEN' => Yii::app()->request->csrfToken), //'data'=>'js:javascript st
//atement' any other data like CSRF tocken to be passed
//if commentd all things will be passed
'url'=>CController::createUrl('BrowserVersion'), //url to call.i.e controller's-action to
),
'empty'=>'Select Browser'
)); ?>
<?php echo $form->error($model,'BrowserId'); ?>
<?php echo $form->labelEx($model,'BrowserVersionId',array('class'=>'control-label')); ?>
<?php echo $form->DropDownList($model, 'BrowserVersionId', array('value'=>isset($model->browserVersion->VersionName) ? $model->browserVersion->VersionName : "Select Version"),array()); ?>
<?php echo $form->error($model,'BrowserVersionId'); ?>
<?php echo $form->labelEx($model,'attachedfiles',array('class'=>'control-label')); ?>
<?php
$this->widget('CMultiFileUpload', array(
'model'=>$model,
//'name'=>'files',
'attribute'=>'attachedfiles',
'accept'=>'jpg|gif|png',
));?>
<?php echo $form->error($model,'attachedfiles'); ?>
<div class="row buttons" style="margin-left: 160px">
<?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save',array('class'=>'btn btn-primary')); ?>
<?php echo CHtml::resetButton('Cancel', array('class'=>'btn btn-primary'));?>
</div>
<?php $this->endWidget(); ?>
And The Controllers Actions
public function actionProjectVersion()
{
if ($_POST['ProjectId']!=='')
{
$data=Projectversion::model()->findAll('ProjectId='.($_POST['ProjectId']));
$data=CHtml::listData($data,'Id','VersionName');
foreach($data as $value=>$name)
{
echo CHtml::tag('option',
array('value'=>$value),CHtml::encode($name),true);
}
} else {
echo CHtml::tag('option',array('value'=>''),CHtml::encode('Select Version'),true);
}
}
public function actionBrowserVersion()
{
if ($_POST['BrowserId']!=='')
{
$data=Browserversion::model()->findAll('BrowserId='.($_POST['BrowserId'])); //if u remove data in _form.php then use ($_POST['Issue']['BrowserId']));
$data=CHtml::listData($data,'Id','VersionName');
foreach($data as $value=>$name)
{
echo CHtml::tag('option',
array('value'=>$value),CHtml::encode($name),true);
}
}
else {
echo CHtml::tag('option',array('value'=>''),CHtml::encode('Select Version'),true);
}
}
Create and Update actions are as it is …

You’re creating the drop down list wrong here:
<?php echo $form->DropDownList($model, 'ProjectVersionId', array(
'value'=>isset($model->projectVersion->VersionName)
? $model->projectVersion->VersionName
: "Select Version")); ?>
Look at the API if you’re unsure how to use a method; it has a pretty good search facility.
Check the correct parameters to provide for CActiveForm::dropDownList() here.
First Problem:
The third parameter is supposed to be the array used to populate the drop down list options. This should be an array in the following format:
array(
'value1'=>'Display Name 1',
'value2'=>'Display Name 2',
...
)
in your case, each value will be a ProjectVersionId and each display name will be the name of that project version.
This is often generated using the CHtml::listData() method.
Second Problem:
The CActiveForm will assign the value automatically, you do not need to do this yourself. If you want to show a prompt, use this form:
$form->dropDownList($model, 'AttrName', $options, array('prompt'=>'Select Version'));
The points above also apply to your browser version drop down list.
I suggest you pay close attention to the API as you try to unpick these problems.
Thank you for taking me to right. n sorry I didn’t get your this point. I mean how it will possible can u pls do the favor.
I tried bt whenever i click on update, it displays "Select Version"(for projectversion)
Done for Updating the existing. But Now the problem is creating new . cos for new the projectId in null.
Thank you my friend i’ve done it. bt i dont knw whether it is right way or not
<?php echo $form->DropDownList($model, 'ProjectVersionId',$model->isNewRecord ? array('prompt'=>'Select Version'):CHtml::listData(Projectversion::model()->findAll('ProjectId='.$model->ProjectId),'Id','VersionName')); ?>
If any, pls draw me to right way …
