Hi Sean, I'm not sure I understand how to repro this exactly.  The steps I tried are below.  Could you please let me know what to change?

- Open the ng2Boilerplate project in WebStorm
- Add a WebStorm breakpoint on someplace like src/public/index.html line 29 (first line of inline script tag)
- Debug using webstorm with a "npm run devserver" config
- Open in Chrome http://localhost:9089/src/public/index.html#/Login/Login
- Remove the Webstorm breakpoint

ok, what seems to be the issue?
an error?
let me know so I can assist

Could you please check is it still a problem with latest stable and if possible in latest Chrome Canary build?

I am using latest release chrome and still an issue, I am not running the beta version though..

Ok, could you provide step-by-step instruction for repro? There are a lot of different steps on sample project page: https://github.com/born2net/ng2Boilerplate .
Should I use gulp or npm? Or just follow debugging guide?

sure I would be glad to help.
so the best thing is to follow these steps:

git clone https://github.com/born2net/ng2Boilerplate.git
cd ng2Boilerplate
npm install -g jspm@beta
npm install -g gulp
npm install

and to debug run:
npm run devserver

continue by putting a breakpoint, do some saves and more saves (hot-reload will re-inject the module) and continue to remove break points.

after a minute of so you will run into a situation where you will hit a breakpoint that has been already removed.

regards

Sean.

by the way if you want to do a GoToMeeting I can connect to you!

sorry I meant TeamViewer

doesn't work for me, any ideas?

yes it seems to be case sensitive, I will soon fix it to all lower case, so if you for example rename to the case it wants as in starwars.ts it will work.
I am on Windows so its a non issue (and I believe its ok on Mac as well, Linux seems to not like the case diff which again I will fix soon)

ok fixed cases, please re-fork

let me know if all good now as I fixed the case issue.
regards

Thank you! I'm able to reproduce. At least DevTools doesn't update source when hotload actually updated it and breakpoints work bad.
I'll take a look.

GREAT! Glad you can see the issue.
Hot-Reload IMHO is the killer app for Angular2 and a fix for this would be greatly appreciated!!!!

let me know if you need help,

regards

Sean,

Andrey, please take a look.
The problem here:
1. hot-reload send new script source with source map;
2. source map contains a lot of files.
3. files content aren't updated in sources panel;

Because we have at least two early exit in CompileScriptMapping.js in function _sourceMapLoaded:
1. if (this._scriptForSourceMap.get(sourceMap)) - yes, sure we have one, loaded on previous hot-reload;
2. if (this._sourceMapForURL.get(sourceURL)) - yes, we add this file on previous source map loaded but we still need to update its content!

Sean, could you try following steps: 
1. open the dev tools console
2. input: eval('const x = 1;\nconsole.log(x);\n//# sourceURL=somescript.js')
3. input: eval('const x = 2;\nconsole.log(x);\n//# sourceURL=somescript.js')
4. Open the somescript.js source and try to set a breakpoint 
5. input: eval('const x = 1;\nconsole.log(x);\n//# sourceURL=somescript.js')
6. Try to make something with breakpoints.
Does this issue look like issue described by you?

I tried it but not sure how to test with hot-reload!?!?

[DevTools] Fixed breakpoints in hotreloaded scripts

We need to use last arrived script for ResourceScriptFile.
Otherwise _isDiverged check will always return true in case of:
eval("source1 //# sourceURL=foo.js")
eval("source2 //# sourceURL=foo.js")
