We are trying to use FlexJS 0.8 with a Visual Studio Code (VSCode) setup (nextgen actionscript extension).
Everything works fine. However, when we use the -source-map option of the compiler (in the asconfig.json) a source map file is created ({project name}.js.map) with the correct keys, but no values ! Here is a copy of the content of the {project name}.js.map : { "version":3, "file":"myproject03.js", "lineCount":1, "mappings":";", "sources":[], "names":[] } I have understood that the map generated from MXML files should be named .mxml.map. But this is not our concern (we can rename the file until this small bug is fixed). The problem is of course that the file is "empty". The project consists of a single mxml file (with a button, a label and a listener displaying an Alert, nothing very complicated !). The listener is inside a script tag, of course, not inlined. We have the latest version of VSCode (august 2017), the latest version of NextGenAS extension (0.6.0). The only specific (?) setting is that we use the --output argument since we want to sent the compiled output to our web server (the output dir is one level BELOW the web root but of course the output dir is specified as an absolute windows path, not as a URL). And also we output JS only (--target JSFlex). The generated output in bin-debug runs fine... What did we miss ? Many thanks Nicolas
