Is there anyway to send a message to a message handler on another page in ignition perspective? I currently have a button that runs this: messageType = “assetParameterHandler” system.perspective.sendMessage(messageType) system.perspective.navigates("/Utilities/Test_Asset") On the page “/Utiliti…

So a couple things here. When you want to send a message across a different scope, you have to set the listener to the scope and then you also need to specify the scope in the script: https://docs.inductiveautomation.com/display/DOC81/system.perspective.sendMessage . See specifically the part about …

[image] Cody Mallonee: system.perspective.navigate("/parameterizedView/2/SomethingElse") here you are sending a hard coded as a param. Is it possible to send as a variable that contains some data?

In 8.1.13 you can also pass URL-encoded query parameters: https://docs.inductiveautomation.com/display/DOC81/Pages+in+Perspective#PagesinPerspective-PassingParameters(URLParameters)
