I'd like to create a Simulink mask where I can comment through or uncomment a sub block of the mask based on one of the mask parameters.

E.g., let s = 0 or 1 be one of the mask parameters. In the Initialization tab of the Mask editor, I have:

mask_block = gcb
switch s
  case 0
      set_param([mask_block '/test_block'], 'Commented', 'through')
  case 1
      set_param([mask_block '/test_block'], 'Commented', 'off')
  otherwise
      error('s must be 0 or 1')
end

This gives an error as soon as I click Apply in the mask editor:

Error in 'test_lib/test_mask':Initialization command cannot be evaluated Caused by: Block 'test_lib/test_mask/test_block/ cannot be commented during execution of a callback.

The interesting thing is that I have no issue if I want to delete the block instead. Am I forced to delete and recreate a block (which could be pretty complicated) in order to get the right dynamic mask behavior? That would be a shame when this very convenient comment through feature is available.

I think I solve the problem at least in Matlab 2023a I haven't test in prevous versions.

try allowing the modification of the mask by using this line in the initialization code of the mask

set_param(gcb, 'MaskSelfModifiable', 'on');

if this is not enough try adding this line for each block you want to modify:

set_param(block_name,'MaskSelfModifiable','on')

you can inspire yourself with this page :

I am having the same issue. Strange that there is no problem deleting blocks or adding new blocks, yet commenting one out is not allowed.

I'm also looking to do something similar - have a button which runs a script to comment out debug logic & scopes in a model. Would like to hear if there's a workaround to the 'cannot be commented out/through during execution of a callback' problem.
