sol | A C11 Lua wrapper - Sol is a C library binding to Lua

The error in this line llaveObj.llaveFa.add(randomNum); coming from llaveFa is not initialized. Let me explain this, in "Nota" class you are declaring in this line ArrayList llaveSol, llaveFa; llaveFa and llaveSol are initialized with null, to fix this you can initialize the variables right in the class itself with something like that: ArrayList llaveFa = new ArrayList();

Your code sends ETH (stated in the _amount variable) from the smart contract to the _recipient. So it doesn't require any ETH to be sent in order to execute the transferEther() function.

If you want your contract to accept ETH, the function that accepts it (or the general fallback() or receive() function) needs to be marked as payable.

Example:

Your code is correct. And TreeTable does show all columns, you just miss the horizontal scroll at bottom of the grid.

To fix the situation, you need to

• init UI in container ( currently it is atached to the body ). To do so you need to add container property to the UI configuration

The .append() function modifies the existing string, so nothing is returned.

So you can just call

You have a couple of issues here. You are displaying a subset (50 records) of the original dataset with 150 records. However, you are trying the change the values in the original dataset. That will not work if you choose anything other than the first selection for Species. Also, when you change your selection, the previous changes are lost. To retain the changes, you need to make the changes in the original dataset also. Next, to ensure that the edited changes are reflected in the sub dataset, you need to subset it outside of output$iris_datatable. Try the code below.

You're trying to invoke renderBirds method but its not defined yet.

Tip: Whenever you code and something doesn't seems to work appropriately try checking console errors. They might help you a lot!

There's currently no namespacing or import X as Y, that would allow to use both interfaces with the same name.

If you don't want to merge the files, you can keep both but need to change the actual interface name of at least one them.

Example:

• ./interfaces/IPair.sol imports ./Pair/IERC20.sol, which defines interface IERC20 {}

  • change the definition to interface IPairERC20 {} and all occurrences that instantiate it (new IERC20() to new IPairERC20())

• ./interfaces/IMasterChef.sol imports ./MasterChef/IERC20.sol, which defines interface IERC20 {}

  • change the definition to interface IMasterChefERC20 {} and all occurrences that instantiate it (new IERC20() to new IMasterChefERC20())

The v, r, and s parameters are a result of signing a message with a private key. The signature has 65 bytes, which are split into 3 parts:

65 byte array (of type bytes in Solidity) arranged the following way: [[v (1)], [r (32)], [s (32)]].

Sign off-chain (because you're using a private key).

Note the address in the comment, we'll verify it on-chain later.

You need to enable gas before You store variables. tvm.accept can do it.
