sl_customization - Update Lookup Table Data (Non-Standard Format)

-In the link below, section "Propagate Nonstandard Format Lookup Table Data", an example is given on how to propogate non-standard lookup table data to the workspace. Is there a way to propogate this to a data dictonary variable instead? The data that is propogated is just the table data and not the breakpoint data, can the breakpoints be accessed as well?

If this isn't possible is there a way to access the table editor data programmatically?

As far as propagating modified data back to its source variable, it doesn't matter whether the source variable is in the base workspace or a SLDD. Try it and it works when the variable is in a SLDD.

I'm still not sure how to prevent a worspace variable from being created using the example provided. The line of code in the example " blkInfo.tableWorkSpaceVarName = 'table3d_map_custom';" makes a workspace variable once the "myConvertTableFcn" is called. How do I set a SLDD variable instead? Also do you know how to access the breakpoints as well?

[Fangjun Jiang]

Migrate your model with base workspace data to using a SLDD. All the changes will be reflected to the SLDD. Use a 2d table example so you will be able to view and change the table data and propagate it back to SLDD.

-My Model is already using a data dictonary. The code I'm using below. You can see in the function "myConvertTableFcn" I had to access the SLDD in order to get anything to be saved to the SLDD. I believe the issue is in tableWorkSpaceVarName class below (Next to the ISSUE HERE? comment). Is there a different class call for the data dictonary?

function sl_customization(cm)
cm.LookupTableEditorCustomizer.getTableConvertToCustomInfoFcnHandle{end+1} = ...
@myGetTableConvertInfoFcn;
end
function blkInfo = myGetTableConvertInfoFcn(blk,tableStr)
        global currentSystem block 
        block = blk;
        currentSystem = gcs;
        nameOfTable = lower(get_param(block,'Name'));
        blkInfo.allowTableConvertLocal = true;
        blkInfo.tableWorkSpaceVarName = nameOfTable; %%%%%%%%%%%%%%%%%ISSUE HERE????
        blkInfo.tableConvertFcnHandle = @myConvertTableFcn;
end
% Converts 3-dimensional lookup table from Simulink format to
% nonstandard format used in workspace variable
function cMap = myConvertTableFcn(data)
    global currentSystem block nameOfTable
        nameOfTable = lower(get_param(block,'Name'));
        tableDimensions = get_param(block,'NumberOfTableDimensions');
        dataDictonary = Simulink.data.dictionary.open(get_param(currentSystem,'DataDictionary'));
        dDataSectObj = getSection(dataDictonary,'Design Data');
        tableEntry = getEntry(dDataSectObj,nameOfTable);
        oldTableVal = getValue(tableEntry);
        if(strcmp(tableDimensions,'1'))%if this table has 1 dimension set y val
        oldTableVal.Value.y = data;
        setValue(tableEntry,oldTableVal);
        elseif(strcmp(tableDimensions,'2'))%if this table has 2 dimension set z val
        oldTableVal.Value.z = data;
        setValue(tableEntry,oldTableVal);    
        end
       cMap = data;
end
