strange problem here. Using Yii framework I have the following class
class HtmlTableUi
{
public function __construct(CWebModule &$module,$data,$actions)
{
//...code goes here...
}
protected function renderTable()
{
//... code goes here ...
}
}
I can call HtmlTableUi::renderTable() from instance of HtmlTableUi in SchedulerModule class which is the main class in a separate application module. My SchedulerModule.php file:
<?php
Yii::import('scheduler.components.HtmlTableUi');
class SchedulerModule extends CWebModule
{
public function init()
{
parent::init();
}
public function beforeControllerAction($controller, $action)
{
return true;
}
public function printUI($data,$actions,$submitPath)
{
$ui = new HtmlTableUi($this,$data,$actions,$submitPath);
$ui->renderTable();
}
}
Here comes the tricky part - when I call SchudulerModule::printUI from view (index.php) this way
<?php
$this->module->printUI($casino,$actions,null);
?>
the code flow goes through SchudulerModule::printUI until reaching the point where renderTable is invoked ($ui->renderTable();) and instead stepping at the first line inside the body of that method it, contrary to any logic and rules, surprisingly jumps to CHttpSession::close !!?
Notice the Call Stack before invoking renderTable
protected/modules/scheduler/SchedulerModule.php.SchedulerModule->printUI:153

Has anyone had similar issue? Can anyone explain that behavior?
I found the solution!!! The access modifier of renderTable is supposed to be public, not protected. This wrong somehow in Yii framework results in unexpected runtime behavior instead of compilation error.
