Change HTML file name


probably a simple question....

I have an existing project called Project and a unit called Unit7. This produces a Project7.js and Unit7.html when compiled.

The settings shows I can change the name of the html file. If I change this to index.html it says the file does not exist.

What is the correct procedure to change this so it produces index.html.

You need to change the filename in the project manager. Did you do it from there?
The project HTML file in the project manager is the one that gets added to the output folder of the web client app.
