Hi,

You need to define the sequence first, for example:

// Slice
module Common
{

sequence<CFuncMenu> CFuncMenuSeq;

class CFuncMenu
{
    string funcID;
    string levelID;
    string levelName;
    string parentID;
    string instanceName;
    CFuncMenuSeq funcChildren;
};

}

Cheers,
Benoit.

there are still errors as blow:
:/work/Projects/qta/Interface/Common.ice:15: `CFuncMenu' is not defined
:/work/Projects/qta/Interface/Common.ice:24: `CFuncMenuSeq' is not defined

Sorry, you need to forward declare the CFuncMenu class for this to work. The following should work instead:

// Slice
module Common
{

class CFuncMenu;
sequence<CFuncMenu> CFuncMenuSeq;

class CFuncMenu
{
    string funcID;
    string levelID;
    string levelName;
    string parentID;
    string instanceName;
    CFuncMenuSeq funcChildren;
};

};

thks very much, from this point of this, slice is very similar to c etc.

thks again.
