Question

Having issues initialising a variable length storage struct, can anyone

explain what I'm doing wrong please?

struct Example {
uint8[2] eg;
bool[2] ex;
address someAddress;
string myString;
}

Example[] internal examples;

function addExample(Example[] _examples) external {
for (uint256 i; i < _examples.length; i++)
examples.push(_examples[i]);

if (_examples.length > 0)
examples[0].eg[1] = 9; //ERROR HERE
}

I'll check this - I'm using it in my base contract, but the error occurs in an inherited contract which doesn't have this in the header so I'll add and make sure this isn't the issue. I think I can use pragma abicoder v2 now as it's no longer experimental
