Channel disconnected error message again and again - Flash builder 4

I'm trying to use server capabilities Flash Builder 4. But using different ways (i use 5 or 6 tutorial) get one and the same error within a week - "Channel disconnected - Channel disconnected before an acknowledgment was received." I looked up "gateway.php" and there was not even a closing tag ?>. Error repeated on a remote server (of course I changed all the settings to the mySQL database). Network monitor also gives error. Show where I can find a solution, please? It m开发者_JAVA技巧ay be to blame Zend? But how to update it?

In your employeeService.php file - as shown below - set the port number to your MySQL port number. Default is 3306.

var $port = "3306";

I can give an example of the error in the tutorial...

If you forget to edit searchBtn_clickHandler method, the Channel Disconnected error will occurs.

Wrong:

getEmployeesResult.token = employeeService.getEmployeesByName(searchTxt.text);

Correct:

if(searchTxt.text!=""){
getEmployeesResult.token = employeeService.getEmployeesByName(searchTxt.text); } else{ getEmployeesResult.token = employeeService.getEmployees(); }
