Hello,
recently, i keep getting this warning whenever i run or save my simulink model:
Warning: Error using Simulink.SLXPart (line 74)
Part name must start with a slash
Error in slxPackager/partDefResources>i_partinfo
Error in slxPackager/partDefResources>i_save
Error in Simulink.SLXPartHandler/pExecute (line 105)
feval(cb,packager);
Error in Simulink.SLXPartHandler/doSave (line 66)
pExecute(obj(i),packager,cb,'Save',logger);
Error in Simulink.SLXPartHandlerRegistrar/executeSaveCallbacks (line 94)
doSave(obj.getHandlers,packager);
Error in slxPackager/executeSaveCallbacks
Error in slxPackager/save
Error in slprivate (line 11)

Error in SimulinkStudio.callbacks.saveCB (line 14)
SLM3I.saveBlockDiagram( cbinfo.model.Handle );
Error in SLStudio.ToolBars
Please give me some tipps on how to solve this issue, thanks :)

Hello Sobhi,
unfortunately no, but since it is only warning and does not disturb the simulation, i just ignore it. Thanks for your question.
Brian

This typically happens when there are unresolved image annotations in the model. When copying an image from the clipboard as an annotation into the model, Windows may not preserve the right path name. So when copying from the clipboard the Windows path may point to a temp folder or a URL if it is from your browser. The result is an annotation with a missing image and hence you get this warning when you try to save the model. The problem should be resolved by using the insert image dialog box for your annotations.

Is there a method to easily identify these unresolved image annotations? The warning does not provide a link/path to the offending image.

Thank you very much. After 4 years I went through my model block by block and I found two image annotations that I deleted and resolved this issue.

I also just had this problem - and it is really annoying. Here is a proposal about how to find such broken annotations, where "bdroot" is the actual Simulink model:
clc
hAnno = find_system( bdroot, ...
'FindAll', 'on', ...
'Type', 'annotation' ...
);
for n = 1 : length(hAnno)
disp('-----------------------------------------');
disp( [' > ' get_param(hAnno(n), 'Parent') ':'] );
disp( get_param(hAnno(n), 'Name') );
end
In the resulting list on the commandscreen, you might see XML-like content, beginning with
<!DOCTYPE HTML PUBLIC ...>
When you see content like this, then it's ok:
<img src="[$unpackedFolder]/simulink/resources/mwimg_ ... -8fae7932e4e5.tif"/>
When you however see something like this, then it might be the cause of your problem:
<img src="D:\users\ ... /mwimg_ ... -2160b69c8c0c.png" />
The, use the Parent of the annotation to navigate to the Simulink SubSystem.
