[Wxlua-users] bugs in namespace bindings?

[k. h. <kla...@nl...>]

Hi,

I think there is someting wrong with the whole binding registration, and 
that because of that things get mixed up.

In wxLuaBinding::RegisterGeneratedClasses() i enabled the print
wxLogDebug(wxT("RegisterGenClasses %d '%s'\n"), iTag, 
lua2wx(pClass->name).c_str());

And i see that my object becomes registrated, but with the same itag as 
the wx binding.
I don't know if this is what casuing it??

14:14:15: RegisterGenClasses 4 'wxlCanObj'
14:14:31: RegisterGenClasses 4 'wxPageSetupDialogData'

Later on i run the next lua script from a file:

blah = wx.wxPageSetupDialogData()
blah:GetPaperSize()

canobj = wxluacan.wxlCanObj()
canobj:Draw( bitmapDC,  0, 0 )

The canobj is really constructed ( breakspoint in C++), but function 
Draw is called on the wrong object, in fact it is called on the wx 
namespace object  with the same iTag being 4.
So the first function is oke, but the second fails. And that is because 
the pclass is the one of the wxPageSetupDialogData, and not of the 
wxlCanObj.

wxLua_lua_getTableFunc(lua_State *L) in the end is able to print the 
function called, and the output indictaes that soemthing is wrong indeed:

14:53:30: class wxPageSetupDialogData function GetPaperSize
14:53:43: wxLua_lua_getTableFunc 'GetPaperSize' pClass 11590824, 
userdata 1, lightuserdata 0, ttag 4, class_tag 4 lua_State 26287736 
wxLuaStateRefData 26278328

14:53:51: class wxPageSetupDialogData function Draw
14:53:52: wxLua_lua_getTableFunc 'Draw' pClass 11590824, userdata 1, 
lightuserdata 0, ttag 4, class_tag 4 lua_State 26287736 
wxLuaStateRefData 26278328

This is all easy to reproduce on the sample i made. This evening i will 
upload this one, with the right rules and wxluacan.i file.
It looks like the namespace is skipped or it is not legal to have 
classes with the same iTag??
What is this Itag??

Hope this is enough to find the bug, i don't know how to solve it myself.
