Hello,

I'm desperately trying to listen to different blocks from my simulink model. The listeners are executed and work properly. I tried to send it to different static fields in my GUI figure. one field for each block. But it doesn't really work. There are 5 Blocks and it works for only (sometimes 2) one of them. The values of the other 4 blocks are shown in the other static field one after another instead one field one block. A few weeks ago everything worked fine.

I'm not able to figure out the problem. I have no clue why it only works for one / two blocks ?!

the programming for the listeners are all the same:

in the GUI.m File's opening function

rto = get_param('simulink_mdl/blk1','RuntimeObject');
str = num2str(rto.OutputPort(1).Data);
statestxt = findobj('Tag','blk1_field');
set(statestxt,'string',str);

and in the block's callback startfcn

set(0,'ShowHiddenHandles','on');
block_1 = 'Simulink_mdl/blk1';
event = 'PostOutputs';
listener = @GUI.m;
h(1) = add_exec_event_listener(block_1, event, listener);
