Trouble initializing UIDropDownMenu from XML

[sigEleven]

Hey All, hoping someone can lend me a hand here.

I've been trying to wrap my head around drop down menus for a while now, and it's surprisingly difficult. After following multiple examples and tutorials that don't work, I've hacked together some operable code to get my drop downs working.

However, I'd like to create the dropdowns in XML, and not clutter up my LUA code with it. The problem I'm noticing right now is that I cannot initialize the dropdowns correctly in XML.

This does not work correctly (I end up with a blank drop down box that says "Custom" with no options):

<Button name="BName" parent="Parent_Frame" inherits="UIDropDownMenuTemplate"> 
   <Scripts>
      <OnLoad>  UIDropDownMenu_Initialize(BName, BName_initialize)</OnLoad>
    </Scripts>
</Button>

However, this works fine in LUA, when placed in the drop down's parent frame onload function.

UIDropDownMenu_Initialize(BName, BName_initialize)

Hopefully I'm just missing something simple, anybody have any idea what's up?

Not sure if that's the problem, but the first argument of your function in your XML code is not the same as in your lua code. BName and BName_Filter.

(1) XML is hideous and ugly, and far more cluttered than any Lua.

(2) Is your "BName_initialize" function already loaded when your XML loads? If not (eg. if you are loading the XML file first, and then the Lua file where the function is defined) then that is your problem.

Thanks for the replies,

Haleth: I caught that, and did an edit, but I guess you got your reply in first. I did confirm the function is correct.

Phanx: I agree; call it an OCD thing, but I'd like all my elements statically created in XML, in a separate file. Confirmed functions (lua file) loading first, then xml.

Has anybody been able to duplicate this, or have any other ideas?

...and needlessly inserting their names into the global namespace.

Yeah, because that bit of memory allocation is going to kill people's machines. Thanks for the help Torhal.
