Blocks not showing in Simulink Library browser (R2015a)

I upgraded from R2014a, and noted that our self-developed libraries are showing empty in the Library browser.

I loaded the library file, then did | set_param(gcs, 'EnableLBRepository', 'on'); | and saved it. I checked by quitting MatLab that after a restart/reload that this property is on, and it was.

I'm using a 'Standard' slblocks.m file next to the .slx library file:

    function blkStruct = slblocks
      % Specify that the product should appear in the library browser
      % and be cached in its repository
      Browser.Library = 'CSI_lib';
      Browser.Name    = 'CSI Library';
      blkStruct.Browser = Browser;

After a LB refresh this library is visible in the LB, but when selecting it the right-hand pane doesn't show any of the blocks that are supposed to be in there.

I was also able to run into this in R2015a, but it was resolved when I saved the model and refreshed the Library Browser.

The problem is that when you do that set_param command, it doesn’t show the model as “dirty” (that is, with the * next to its name). However, you still have to save it first.

From a command-line perspective, you can do:

slxFile = 'mylibname'; 
load_system(slxFile);
set_param(slxFile,'Lock','off');   
set_param(slxFile,'EnableLBRepository','on');  
save_system(slxFile);
