Please give a brief summary of your issue:
I’m using PDFTRON to display a PDF Form which is bi-directionally coupled to an HTML form. I watch for changes to the PDF fields, and then update the HTML form; I also watch for changes to the HTML form and use field.setValue() to update the PDF field. Because field.setValue() fires a fieldChange event, I end up with extra logic to avoid a cascade of setValues => fieldChanged => setValue => etc…

Is there a way to either:

  • Call setValue without firing the fieldChange event, or
  • See why a fieldChange event was fired (e.g. user input vs programatic change).

Hello Tim,

Unfortunately, there is no API that can do this as of now.

However, I suggest using a state variable to keep track of when a user updates the value within your application and use it to determine which logic to execute resetting it to false after the event.

Please let me know if this doesn’t work for your application.
