NOT ENTERING FUNCTION

I copied the procedure from the sdk but for some reason the getcontent() function is never entered. Why is this?  If i run the code under getcontent() from inside the init, it works. It does enter the init.

<?xml version="1.0" encoding="utf-8" ?>

<component name="ContentReader" extends="Task" >

<interface>
   <field id="content" type="node" />

</interface>


<script type="text/brightscript">
<![CDATA[
sub init()
print "INT"
m.top.functionName = "getcontent"
end sub

sub getcontent()
Print "GETCONTENT"
iconurl=[]
scrollist=[]
content= createObject("RoSGNode","ContentNode")
url="http://rokulist.php"
ut = CreateObject("roUrlTransfer")
ut.SetUrl(url)
rocontent = ParseJson(ut.GetToString())
 for each items in rocontent.items
iconurl.Push(items.icon)
end for

scrollist=arraySlice(iconurl,0,5)

for each item in scrollist
items = content.CreateChild("ContentNode")
items.HDSMALLICONURL = item
?items.HDSMALLICONURL
end for

m.top.content = content

end sub

function arraySlice(arr, start=invalid, finish=invalid, step_=1):
res = [ ]
for Q = start to finish step step_:
   if step_ = 0 then print "ValueError: slice step cannot be zero" : STOP
   if start = invalid then if step_ > 0 then start = 0 else start = arr.count() - 1
   if finish = invalid then if step_ > 0 then finish = arr.count() - 1 else finish = 0
   if start < 0 then start = arr.count() + start 'negative counts backwards from the end
   if finish < 0 then finish = arr.count() + finish
   res.push(arr[Q])
'?res
 end for
return res
 end function

Re: NOT ENTERING FUNCTION

There's nothing in the code you pasted that actually runs the Task.  You need to set the task's control to "RUN" to get it to spin up its thread.
