Hi, I started to learn Solidity by examples in Ethereum Studio. Everything worked fine, but some day (maybe after some updates), the sample projects stopped working. For example the Hello World project:
- I can create and open a new project based on Hello World template
- It is also possible to compile and to deploy the contract
- Direct interaction with the contract through the leftside panel also works fine, I can change the message and I see the transactions in the right side “Transactions” panel.
- But: the preview pane doesn’t show the values - the values in the Message and Block number fields are empty. As the script wouldn’t have acces to the contract in blockchain.
It seems that the java script in app.js cannot somehow access the contract. In the console window of the browser there is no error message. The call to the contract by this.instance.message() is called from within the app.js script, but no response comes from the blockhain contract. And therefore nothing is shown in the preview pane.
I tried different browsers and I tried also on another computer.
Nothing has helped.
Can you help please?
