Details:
This is a spin-off from bug #46115 (host container message delimiter issue),
and bug #37223 (JavaScript-to-Flash ExternalInterface issue).
While I was testing on Gnash's container-player communication issue,
I have found that while Gnash's implementation of `ExternalInterface.call()`
calls JavaScript function with correct (String) arguments;
return value from JavaScript, however, *is passed to ActionScript as
`undefined`*.
I have created a minimal Flash file (Flash 8) using MTASC, to demonstrate
the issue by calling a simple JavaScript function from ActionScript side.
Following is a trace log from `flash2js.html` on browser with Adobe Flash
Player:
flash2js: calling JavaScript function "flash_call"...
flash2js: OK: JavaScript function correctly returned "Too"
You'd see that JavaScript is called and its String return value is passed
correctly.
Following is a trace log from `flash2js.html` on browser with Gnash:
TRACE: flash2js: calling JavaScript function "flash_call"...
TRACE: flash2js: failed: expected return value "Too", got "undefined"
You'd see that JavaScript's return value is passed to ActionScript code as
`undefined`.
Test Flash file, build scripts, debug logs, plugin-player communication logs,
and screenshots are attached as `flash2js.zip`.
Note: This problem is likely to be originated from the player itself
(not libgnashplugin), as the return value string is correctly shown up
in container-to-player communication log.
