This commit ( https://github.com/codecat/angelscript-mirror/commit/3599b250cb1c0df820f38e71c91c7d46338cef90​ ) seemed to have broken a lot of my script bindings that relate to using ?&in parameters. For example:

[    ScriptEngine] [12:56:25] [VehicleState]  VehicleState/Debugger/Main.as (45, 2) : INFO : Compiling void TabPlayerStates()
[    ScriptEngine] [12:56:25] [VehicleState]  VehicleState/Debugger/Main.as (76, 4) :  ERR : Multiple matching signatures to 'UI::PushID(const wstring&)'
[    ScriptEngine] [12:56:25] [VehicleState]  VehicleState/Debugger/Main.as (76, 4) : INFO : void PushID(const ?&in)
[    ScriptEngine] [12:56:25] [VehicleState]  VehicleState/Debugger/Main.as (76, 4) : INFO : void PushID(const string&in id)

And:

[    ScriptEngine] [12:56:25] [PluginManager]  PluginManager/src/Interface/Tabs/Plugin.as (64, 2) : INFO : Compiling void PluginTab::CheckRequestChangelog()
[    ScriptEngine] [12:56:25] [PluginManager]  PluginManager/src/Interface/Tabs/Plugin.as (79, 5) :  ERR : Multiple matching signatures to 'warn(Json::Value@&)'
[    ScriptEngine] [12:56:25] [PluginManager]  PluginManager/src/Interface/Tabs/Plugin.as (79, 5) : INFO : void warn(const string&in)
[    ScriptEngine] [12:56:25] [PluginManager]  PluginManager/src/Interface/Tabs/Plugin.as (79, 5) : INFO : void warn(?&in)

Is this a bug or an expected consequence of the change? If it's expected, is there a better way for me to handle this, or perhaps an engine property that reverts this behavior?

This appears to be a bug, it was definitely not an intentional change.

May I ask what your conversion operators for wstring and Json::Value to string look like, i.e. the function signature? I'll try to reproduce this and understand why this is happening after the change in above commit.

Can you provide your engine configuration again? (see WriteConfigToFile from the helper functions add-on )

I would also like to see the code for TabPlayerStates and PluginTab::CheckRequestChangelog, especially the code related to the error messages.

Relevant string behavior & methods:

void f(const wstring &in) // Constructor
wstring opImplConv() const // Method

For wstring:

void f(const string &in) // Constructor
string opImplConv() const // Method

For Json::Value:

Value@ f(const ?&in) // Factory
string opImplConv() const // Method

The source code for TabPlayerStates: https://github.com/openplanet-nl/vehiclestate/blob/3d106901a5e6b0c932bf08be00ded7b51fc50e1e/Debugger/Main.as#L76​

The source code for CheckRequestChangelog: https://github.com/openplanet-nl/plugin-manager/blob/c1d86473d0cb5a8f27591f7e5edb3f8b0ae2a6c5/src/Interface/Tabs/Plugin.as#L79​​

Let me know if you still need the WriteConfigToFile output. Takes me a bit longer to set up :D

I've fixed this in 2877. Let me know if you have any more issues.

Thanks,
Andreas
