I have an application that through ajax calls a task.
It goes like this, webpage->rest controller->system( task)-> response -> webpage.
The problem is that the task has some "Cli::write(stuff)" that get somehow inside the response of the rest controller...
I cannot get rid of them (I don't want to stop using Cli::write) even if I return $this->response(array('no'=>'thing');
What on earth is happening? I checked out the Rest core code. It seems ok. If this was C I would say that something is writing in somebody's else memory...
Cli::write() writes, like echo does, to the output device. Normally for a task that is the console, but if you call it interactively (or through a rest service), the writes will be part of the output.
You can remove this by wrapping the call to the task in output buffering, using ob_start() and ob_clean(), this will buffer and remove any console output the task produces.
