How to have an address inside a solidity Struct?

Question

My problem

Suppose I have this struct:

struct TextThatWorks {
        bytes32 text;
        uint reads;
}

How can I add a address variable to it?

What I tried

I tried simply adding address someadress; inside the struct declaration, like so:

struct TextThatDoesNotWork {
        bytes32 text;
        uint reads;
        address addr;
}

I have seen many examples doing this exact same thing. Example: Solidity Docs

But when I do this, my functions break.

What happens when I try the above

What works

So, in my contract I have a Text array:

TextThatWorks[] public textArray;

And I have a function to recall the texts inside this array, which returns arrays:

function listTexts () public view returns (bytes32[], uint[]) {

        bytes32[] memory texts = new bytes32[](textArray.length);
        uint[] memory readsArray = new uint[](textArray.length);

        for (uint i = 0; i < textArray.length; i++){
            texts[i] = textArray[i].text;
            readsArray[i] = textArray[i].reads;
        }

        return (texts, readsArray);

}

This returns a nice array in the format [["some hexadecimal example"],[12]]

What does not work

The second struct, TextThatDoesNotWork, only differs of TextThatWorks because it has an address field.

When I use it, my listTexts() function stops working. It always returns empty arrays like [[],[],[]]

To accomodate the additional field, my listTexts() function becomes the following:

function listTexts () public view returns (bytes32[], uint[], address[]) {

        bytes32[] memory texts = new bytes32[](textArray.length);
        uint[] memory readsArray = new uint[](textArray.length);
        address[] memory addresses = new address[](textArray.length);

        for (uint i = 0; i < textArray.length; i++){
            texts[i] = textArray[i].text;
            readsArray[i] = textArray[i].reads;
            addresses[i] = textArray[i].addr;
        }

        return (texts, readsArray, addresses);

}

How I fill the array

function put(bytes32 _text, uint _reads) public returns (uint){
    return textArray.push(TextThatDoesNotWork({
        text: _text,
        reads: _reads,
        addr: msg.sender
    }))-1;
}

Answer 1

Make sure that you fill the array properly

TextThatDoesNotWork[] textArray;

function put(bytes32 s, uint r, address a) public {
    textArray.push(TextThatDoesNotWork({
        text: s, 
        reads: r,
        addr: a
    }));
}
