TMS Web Core is an increditble tool for developing web apps using much of the same tooling and knowledge that has become second nature for Delphi developers. But developing a form for a web page is a very different thing than developing a form in a VCL app or even a FireMonkey app. Different doesn't necessarily mean worse, just different. There are quite a few things that are likely to trip up even the most accomplished Delphi developer along the way.
This post is meant as a repository for this kind of thing, so I'd like to invite everyone to add something here that they've run into that might help others along the way. Or maybe a link to another post either here in the TMS Support Center or elsewhere that was helpful in tackling a particular problem. Mostly thinking of simpler just-getting-started kinds of problems here, not esoteric only-ever-applies-to-my-project-on-the-second-full-moon-of-an-odd-numbered-month kinds of problems
