And indeed, in
> Changeset: https://bitbucket.org/JonathanYap/storm-899
you changed type of the object pointed to by mAttachments from
LLFlatListView to LLFlatListViewEx. The only constructor of the latter
class
<https://bitbucket.org/JonathanYap/storm-899/src/39afebbcccb7/indra/llui/llflatlistview.h#cl-496>
is protected <http://www.cppreference.com/wiki/keywords/protected>, so
only its own methods and methods of its descendant classes may produce
new LLFlatListViewEx objects. LLUICtrlFactory is not a direct or
indirect child of LLFlatListViewEx, but probably responsible for
creating all user interface controls, so this has to fail.
A quick'n'dirty workaround would be to make the constructor public.
Though, looking at the doxygen comment of LLFlatListViewEx
<https://bitbucket.org/JonathanYap/storm-899/src/39afebbcccb7/indra/llui/llflatlistview.h#cl-439>,
the constructor being protected is probably on purpose, as the class "is
intended to be used as a base class for lists which should support two
different messages for empty state.", which might mean it isn't meant to
be used directly.
So the right thing to do is probably to look at its concrete descendants
<http://developer.dimentox.com/d7/dd1/classLLFlatListViewEx.html> (click
"Inheritance diagram for LLFlatListViewEx") and see whether one of them
fits your purpose (maybe LLWearableItemsList?), or, failing that, to
derive your own sub-class from LLFlatListViewEx.
Cheers,
Boroondas
