what's mean of the error?

[badgunnokia]

i have a class implements from commandListener:

class MyListener implements CommandListener
{
private MIDlet midlet = null;
MyListener(MIDlet mid)
{
midlet = mid;
}

public void commandAction(Command com, Displayable dis)
{
/*
if(dis == Display.getDisplay(midlet).getCurrent())
{

}
*/
}
}

when i remark :/*
if(dis == Display.getDisplay(midlet).getCurrent())
{

}
*/
my app run successfully, otherwise , the emulator report the error like below:

Are you sure that you always preverify your MIDlet?

It looks like if you forget to preverify, when you remove comment...
