Hi Bjoern,
I have hit a problem that i don't fully understand. Disabled items are
SfxVoidItem with Which 0, but inserted with different one. State of Item is
check with TYPE Macro as below
> if ( (*ppFnd)->Type() == TYPE(SfxVoidItem) )
> return SFX_ITEM_DISABLED;

So it just type that decides about disabled state of item. I've changed
places where conditions like
> if( !(*ppFnd)->Which() )
>
to
> if ( (*ppFnd)->ISA(SfxVoidItem) )

because I saw in an assert that this is used. At this moment problem
started, code compiles but fails at runtime with segfault at
itemset.cxx:313 (line like above)
I've checked with gdb that there is no method ISA, but IsA. With the
changed method to IsA code does not compile.

Moreover I tried the way with Type and TYPE with no success, gdb output
below:

Thanks in advance for help :)
