PartialTriggers to a trh:script is not working.

Question

<af:panelGroupLayout layout="scroll"
id="pgl3">
<af:panelBox text="Click arrow at left to hide message"
id="pb3" clientComponent="true"
binding="#{TextScrollerBean.tickerPanel}"
inlineStyle="margin-right:10px;margin-left:10px;"
contentStyle="height:55px;"
rendered="#{TextScrollerBean.panelRendered}">
<trh:script id="ppr-hook" partialTriggers="::poll1" text="alert('button pressed');"/>
<af:poll id="poll1" interval="5000"/>
</af:panelBox>
</af:panelGroupLayout>
Does not work. I am expecting the alert to appear, but nothing happens. I have tried "poll1" for the partialTriggers and that does not work either. And I have also tried "pb3:poll1".
Please tell me how to get this to work. It is urgent because it is part of a Proof of Concept for a customer.
Thanks,

TheGoose,
oh, and mixing trinidad and adf is supportedIn general, that is not true. It may have been true in the past, but things do change ({thread:id=2280199}). In your case, it's may be OK, but:
af:resource is the supported way in 11.x to include custom JavaScript in a page.
At any rate, putting a partialTrigger attribute on a trh:script doesn't cause any function in the script to execute when it is triggered by PPR (it could possibly update it's contents via changes to the script or text attributes, but it doesn't AFAIK cause the script to fire). There are 2 ways I can think of to do what you want:
1). Do the update on the server side in a poll listener
2). Use a poll listener on the server side to inject JavaScript back to the client (search the forum or Google for extendedrenderkitservice to find an example or 50)
If this is for your "ticker" - having your af:poll fire every .4 seconds isn't going to be "nice" from a performance perspective, so I'll add another possibility or two (both of which are going to involve some complexity):
3). Write your own custom component to display your ticker, retrieving "chunks" of data from the server (in other words, don't poll every .4 seconds).
4). If you really need something to be updating in "real-time," you could use something like an applet
