setSelectionPosition() can't get to select text

[pr6i6e6st]

edit: solved! had to use the onChar() function instead of calling the function with onValueChanged()

hey guys. i'm trying to get an autocomplete working for a search function and the autocomplete part is working, but i'm not getting an actual selection in the UI. my Debug pulls up numbers, i'm just not getting the selection so that the autocomplete is removed if one keeps typing.
here's what i've got. is it the control? or am i missing a crucial step?




<basicstring name="searchname">
<anchored position="insidetopleft" height="25">
<left anchor="center" offset="-80" />
<top offset="80" />
<right anchor="center" offset="80" />
</anchored>
<empty text="~NPC name~" />
<script>
function onInit()
LastCheck = 0;
LoopBreaker = true;
end
function onValueChanged()
local testText = Module.getModules();
local DataSourceCheck = window.npcdatasource.getValue();
local DBNPCs = DB.getChildren("npc");
local aAutoFill = {};
-----------clipped irrelevant lines here ------
if DataSourceCheck == 0 then
if #getValue() &gt; 2 then
DBAutocomplete();
end
-----------clipped irrelevant lines here ------
end
end
function DBAutocomplete()
local DBNPCs = DB.getChildren("npc");
local aAutoFill = {};
for k,w in pairs(DBNPCs) do
local kDatabaseNode = DB.getChild("npc", k);
local s = DB.getValue(kDatabaseNode, "name", "");
if s ~= "" then
table.insert(aAutoFill, s);
end
end
Debug.console("getCursorPosition(), #getValue()", #getValue(), getCursorPosition());
if getCursorPosition() == #getValue() then
local Curser = getCursorPosition();
local AutoComplete = StringManager.autoComplete(aAutoFill, getValue(), true);
if AutoComplete then
Debug.console(AutoComplete);
if getValue() ~= "" then
local sNewValue = string.sub(getValue(), 1, getCursorPosition()-1) .. AutoComplete .. string.sub(getValue(), getCursorPosition());
currentType = getValue();
setValue(currentType .. AutoComplete);
setSelectionPosition(#getValue());
Debug.console("#getValue(), getCursorPosition(), #AutoComplete, getSelectionPosition()", #getValue(), getCursorPosition(), #AutoComplete, getSelectionPosition());
end
end
end
end
function endLoopBreaker()
LoopBreaker = true;
end
</script>
</basicstring>
