[Laszlo-dev] Re: [Internal-Dev] Fwd: [JIRA] Created: (LPP-975) context menu stops working when modal dialog is displayed

[Henry Minsky]

Here's a meta-issue also, for the language architects ...

If I want to define new LZX tags <contextmenu> and <contextmenuitem>,
I can add these manually to the primitive schema, and add an entry to the
magic
table that maps these to "Lz" class names (i.e., LzContextMenu,
LzContextMenuItem).

That means adding this stuff to the LFC. But we frown on bloating the LFC,
so instead we could put the whole implementation in an optional or
auto-loaded library. But if we're defining the classes in LZX, we don't have
this duality of class names. So would we name the tag <contextmenu> or
<LzContextMenu>? Because if someone wants to generate these menus
procedurally at runtime (Elliot does), then they would the expect the
classes to be named LzMumble, right?

We're digging ourselves into a hole either way -- we really need to bring
the LZX and script naming conventions for classes into better alignment
somehow.
