Re: [xmlvm-dev] Crash in XMLVM new-ios-api when app is started from another app

[Arno P. <ar...@pu...>]

that is some fine debugging you did there!

Please note that the patch you sent makes changes to code that was 
generated by crossmobile. For a proper fix, checkout crossmobile, edit 
file advisor.xml and look for the line <alias name ="__NSCFDictionary"/>

Underneath you should add a second alias for __NSDictionaryM. Once you 
have done that, run ant gen-xmlvm-ios in the crossmobile directory. This 
will re-generate the wrapper code.
