I think you'll find your answer here in "Struct array errors." Even though this is a class, similar rules apply.

Unfortunately missing [] is not the cause, since adding them causes more errors. The cause is that you cannot assign the same value to all fields of the same name at once, you must do it one at a time, as in the following code:

So you'll need:

for ii=1:100
  vecMyArray(ii).dblMyProperty1 = ii;
end

I know it's not satisfying, but I think it at least helps us to definitively understand this error.
