Model Advisor "Fix" Button Disabled in Toolbar but functional via "Fix this Check"

I have a functional model advisor custom check with a "fix" solution implemented (also functional). However the "fix" button is disabled in the toolbar, but I can right-click the failed check and click "fix this check", and the fix solution works as expected. How do I get the toolbar enabled?

All of the help I see on the topic uses a style type of "DetailStyle" whereas I am using "StyleOne" (this is older code I am using in a newer version of matlab). I would like to avoid changing the style type.

My fix is implented as follows:

if self.HasFix
    myAction = ModelAdvisor.Action;
    myAction.setCallbackFcn(@self.Fix);
    myAction.Name = self.FixName;
    myAction.Description = self.FixDescription;
    rec.setAction(myAction);
end

Everything works, just the toolbar "fix" button is disabled for some reason!

Hi Natalie,

I was able to come across the function “setActionEnable” to enable the “fix” icon in the toolbar for the custom Model Advisor check which you have authored.

On a high level, the function can be used inside your “StyleOne” check as follows:

mdladvObj = Simulink.ModelAdvisor.getModelAdvisor(system);
mdladvObj.setActionEnable(true);   

You can take a look at the full sample code that I’ve written below:

function sl_customization(cm)
% register custom checks
cm.addModelAdvisorCheckFcn(@defineModelAdvisorChecks);

end
% -----------------------------
% defines Model Advisor Checks
% -----------------------------
function defineModelAdvisorChecks
% Create ModelAdvisor.Check object and set properties.
rec = ModelAdvisor.Check('com.mathworks.sample.StyleOne');
rec.Title = 'Check whether block names appear below blocks';
rec.TitleTips = 'Check position of block names';
rec.setCallbackFcn(@SampleStyleOneCallback,'None','StyleOne');
% Create ModelAdvisor.Action object for setting fix operation.
myAction = ModelAdvisor.Action;
myAction.setCallbackFcn(@ActionCB);
myAction.Name='Make block names appear below blocks';
myAction.Description='Click the button to place block names below blocks';
rec.setAction(myAction);
mdladvRoot = ModelAdvisor.Root;
mdladvRoot.publish(rec, 'My_Demo');
end


function result = SampleStyleOneCallback(system)
ft = ModelAdvisor.FormatTemplate('TableTemplate');
setTableTitle(ft,{'Blocks in Model'});
setColTitles(ft,{'Index','Block Name'});
allBlocks = find_system(system);
for inx = 2:length(allBlocks)
    addRow(ft,{inx-1,allBlocks(inx)});
end
result = ft;

mdladvObj = Simulink.ModelAdvisor.getModelAdvisor(system);
mdladvObj.setActionEnable(true); 
end


% -----------------------------
% This action callback function changes the location of block names. 
% -----------------------------
function result = ActionCB(taskobj)
mdladvObj = taskobj.MAObj;
checkObj = taskobj.Check;
resultDetailObjs = checkObj.ResultDetails;
for i=1:numel(resultDetailObjs)
    % take some action for each of them
    block=Simulink.ID.getHandle(resultDetailObjs(i).Data);
    set_param(block,'NamePlacement','normal');
end

result = ModelAdvisor.Text('Changed the location such that the block name is below the block.');
mdladvObj.setActionEnable(false);
end

I’ve found the following resources useful regarding the “StyleOne” Model Advisor checks and you may want to refer to the same:

The following documentation explain the input and outputs for the various “callback” styles:

https://www.mathworks.com/help/slcheck/ref/modeladvisor.check.callbackstyle.html

Documentation for “SetActionEnable” function:

https://www.mathworks.com/help/simulink/slref/simulink.modeladvisor.setactionenable.html?s_tid=doc_ta

Refer the “Object Functions” section in the documentation for ModelAdvisor.FormatTemplate. Some of these pages have examples of “StyleOne” Model Advisor callbacks:
