I have an object with ports and I want to check if they are all connected.
But when I do something like this:

@cnt = '0'
foreach .TopicPublisher {
do #PubSubConnector {
 @++cnt%null
 @connected = 'F'
 do ~ToTopic~From.() {
@connected = 'T'
 }
 if @connected = 'F' then
@error = 'T'
' not connected' newline
 endif
}}

than the counter is stuck at 2 , this  means only do #PubSubConnector is 'entered' when it is already connected. It seems the connector does not exist if nothing is connected to it. 
So how can I check if every connector (all 4 in the picture below) is connected to something?

Yes, do #() shows all connected ports. To make comparison the generator must compare connections via ports with the all possible ports available. Depending on the metamodel, all possible ports are  defined in a subgraph, as properties of the object (‘TopicPublisher’), or somewhere else.

Demo repository includes a project ‘EAST-ADL’ in which graph type ‘HardwareComponentType’ has quite similar functionality discussed here. Please check generator named ‘Unconnected pins’. It is run as a part of LiveCheck generator showing at modeling time the status of unconnected pins. In this example the pins (ports) are defined in the subgraph, so the generator seeks all available ports from there. If your metamodel defined ports similarly in a subgraph the right would be something like:

subreport '_translators' run
/* Reports the unconnected ports */
foreach .TopicPublisher {
@ports = ' '
@unused_ports = ''
/* Set the ports variable to include all the connected ports */
do #() { local 'ports' append oid ' ' close }
/* Compares all the ports with the connected ports */
do decompositions
{ foreach .(*Port*) { /* take only elements named as *Port* */
if not @ports =~ oid%wildsp then
local 'unused_ports' append id newline close
endif
}
}
/* Report all the unconnected pins */
do @unused_ports where id
{ id ' not connected' newline
}
}

If ports are defined as properties of TopicPublisher the ports must be stored differently etc.
