I have a template with a repeater that repeats a custom button template. The parent template's custom property is bound to a tag. The repeater's templateParams, inside the parent template, is bound to a SQL query. Once the SQL executes and repeats my custom button template, I need to toggle the first button. What I have tried is to execute a script when the repeater's templateParams changes. However at this point, getLoadedTemplates() returns an empty array. Is there a different approach to this?

Meh, so instead I am watching the “instanceName” property of the child template. When I see a change, I call a function on the parent template which increments an internal property. When that internal property == repeater’s templateParams, then I execute a ‘onTemplateReady’ function where I can use getLoadedTemplates(). Seems to work ok. ---

do you have sample code sir? ---

This might be a good place to use [`system.util.invokeLater`](https://docs.inductiveautomation.com/display/DOC79/system.util.invokeLater)? I can’t remember if template loading is synchronous (probably) so invokeLater should put your actions after the template loading in the EDT. ---

Question, how would you do this from a Client Message Handler? My example: - window with a repeater, repeatBehavior=Count - Window.internalFrame.internalFrameActivated call system.util.sendMessage - Inside the message handler, find the repeater and call getLoadedTemplates() I tried different threading models for the message handler and I also tried invokeLater within the message handler. None worked.
