type mismatch

[mohamed]

Have you any idea how can I solve this problem,

model tableau
 String tab[8];
equation
 tab=getVariableNameTable(2,8);
end tableau;
*************


function getVariableNameTable
  extends modelInExpressionBase;
public
  input Integer indexModel ;
  input Integer dim;
  output String variableNameTable[dim] ;
algorithm
   if indexModel == 1 then   // model1
    variableNameTable[1:size(model2,1)]  := model1[:];
   elseif indexModel == 2 then  // model2  
    variableNameTable [1:size(model2,1)]:= model2[:];
   end if;
end getVariableNameTable;
********************************************

record modelInExpressionBase
public
    final constant String model1[8] =    {"a", "b", "c", "d", "e", "f", "g","h"};
    final constant String model2[8] = {"a", "b", "c", "d", "e", "f", "g", "i"};
end modelInExpressionBase;
********************************************

Error: Type mismatch in assignment in variableNameTable[{1,2,3,4,5,6,7,8}] := {\"a\",\"b\",\"c\",\"d\",\"e\",\"f\",\"g\",\"h\"} of String[dim] := String[8]
Error:
 Error occurred while flattening model tableau

Thank you in advance,

Best regards,
