Yii Booster Button And Errorsummary Problem

Hi guys

I’ve got this little form with 4 different submit buttons:




<div class="form">


	<?php 

		$form=$this->beginWidget('CActiveForm', array(

			'id'=>'login-form',

			'enableAjaxValidation'=>false,

			'enableClientValidation'=>false,

			'clientOptions'=>array(

				'validateOnSubmit'=>true,

			),

		));

	?>


		<?php echo $form->errorSummary($loginModel); ?>


		<div>

			<?php echo $form->labelEx($loginModel,'usrF1_username'); ?>

			<?php echo $form->textField($loginModel,'usrF1_username',

				array('autocomplete' => 'on')); ?>

		</div>


		<div>

			<?php echo $form->labelEx($loginModel,'usrF1_password'); ?>

			<?php echo $form->passwordField($loginModel,'usrF1_password',

				array('autocomplete' => 'off')); ?>

		</div>

		

		<!-- Buttons -->		

		<div> 

			<!-- Yii Booster Button Group -->

			<?php		

				this->widget('common.extensions.bootstrap.widgets.TbButtonGroup', array(

				'buttons'=>array(

					array('label'=>'Submit', 'url'	=>	Yii::app()->createUrl("site/login"),),

				),

			)); ?>

			

			<!-- Yii Booster Single Button -->

			<?php $this->widget('bootstrap.widgets.TbButton',array(

				'label' => 'Submit', 'url'	=>	Yii::app()->createUrl("site/login"),

			)); ?>

			

			<!-- Yii CHtml::link Button -->

			<?php

				echo CHtml::link('Submit','#', array('submit'=>$this->createUrl('site/login'),)

			); ?>

			

			<!-- Twitter Bootstrap Button -->

		    	<div class="btn-toolbar">

			    <div class="btn-group">

			    	<button class="btn">Submit</button>

			    </div>

			</div>

		</div>


	<?php $this->endWidget(); ?>

</div>



All 4 buttons find the correct controller/action, but only the last 2 buttons (Yii CHtml and Twitter Bootstrap) results in the errorSummary being displayed.

With the first 2 buttons (Yii Booster), the errorSummary is not displayed.

Any ideas?

Thanx
