V7.6.0 callFunc()

Does the callFunc() feature work in V7.6? Trying to use it based on the sdk and only getting an error that Interface not a member of BrightScript Component (runtime error &hf3). Setting it up as follows.

dialoginterface.xml

<?xml version = "1.0" encoding = "utf-8" ?>
<component name = "mydialog" extends = "Scene" >
  <interface>
<function name = "generalDialog" />
    </interface>
<script type="text/brightscript" uri="pkg:/components/dialogs/Dialogs.brs" />

  <script type = "text/brightscript" />
</component>


setinfo.brs


function setinfo()
dialogtitle="TITLE TEST"
dialogmessage = "MESSAGE TEST"
params = {title:dialogtitle, message:dialogmessage}
m.mydialog.callFunc("generaldialog", params)
end function




dialogs.brs
function generalDialog(params as Object) as Object
?"in generalDialog"
title= m.top.findNode(title)
message=m.top.findNode(message)
m.background  = m.top.findNode("Background")
example = m.top.findNode("instructLabel")
examplerect = example.boundingRect()
centerx = (1280 - examplerect.width) / 2
centery = (720 - examplerect.height) / 2
example.translation = [ centerx, centery ]
m.top.setFocus(true)
di = CreateObject ("roDeviceInfo")
serial=di.GetDeviceUniqueId()
dialog = createObject("roSGNode", "Dialog")
dialog.title = title
dialog.optionsDialog = true
dialog.message = message
m.top.dialog = dialog
end function

    Maybe the function name is case sensitive when using callFunc? you are calling "generaldialog" but the function is defined as "generalDialog". Just a guess.

    also, what's up with this code? you aren't using your params and the findNode call expects a string.
    title= m.top.findNode(title)
    message=m.top.findNode(message)

    You maybe correct. I'll try and post whether it made a difference.  Thanks for the catch.

    Update: matching the case didn't fix it. Still get Interface not a member of BrightScript Component (runtime error &hf3).
    Thanks anyway

    FWIW, I am using callFunc extensively without issue. The biggest mistake I keep making is defining a function then calling it with dot notation like I am using a normal language, ha ha.
    You should comment out all the code in your function except a print statement, then test. posting the actual telnet log would help.

    Are you creating the interface field in a scene as I have done in the code above?

    I only use it on components that extend Group and Task, not sure if functions are allowed on a Scene.

    I have pretty much cut it down to nothing  and getting error "Member function not found in BrightScript Component or interface."

    mysetup.brs
    function mysetup()
    m.mytestTask=CreateObject("RoSGNode", "mytest")
    m.mytestTask.callFunc("functiontest")
    end function

    functiontest.xml

    <?xml version="1.0" encoding="utf-8" ?>
    <!--********** Copyright 2016 Roku Corp.  All Rights Reserved. **********-->
    <component name = "mytest" extends = "Task" >
      <interface>
    <field id = "content" type = "node" />
    <function name = "functiontest" />
    </interface>
     <script type="text/brightscript" uri="pkg:/components/functiontest.brs" />
    <script type = "text/brightscript" />
    </component>


    functiontest.brs
    function functiontest()
    ?"I AM HERE"
    end function

    All of the above files are located  pkg:/components directory. I understand the error but not sure why it's not seeing the function.

    weird. 
    I looked through my code and I only use functions in components that extend Group. Perhaps SG doesn't allow functions on Tasks?

    I'll try that and see what happens. I don't think I can cut it down much more than what I posted. Not sure if it makes any difference but during the process of trying to call the function I have a busy spinner running, not sure but maybe this causes a problem. Thanks for looking.

    I just tried to add a function interface to a Task, and it doesn't work. I guess the Task node type doesn't support this.

    Warning calling function in myTask
    no function interface specified for test
