How to access Workflow variables in Form Designer?

Question

Hello,
I am wanting to set certain subforms to readonly depending on which part of the workflow the form is currently on. I already have the JavaScript code working to set the subform fields to readonly, but now I cannot figure out how to trigger this and where do I keep a variable to keep track of which part of the workflow I am currently in.
I assume I will have a variable in the workflow itself and then I can use the Set Value QPAC to change the variable for each workflow step before it goes to the User QPAC, but what about within the form? I don't understand how the form javascript will know to execute, so how does my workflow "talk" to the form to set these fields to readonly?
Right now the JavaScript code is sitting in the root::initialize part of the form. I was assuming I could have something like "if my workflow variable is equal to XX then set this subform to read only". But, how do I access my workflow variable in the form designer?
Also, since I have digital signatures, I am having to pass all the form data in document variables, will this affect how I need to do this? I was also thinking of possibly accessing/setting a hidden field in the form, but thought the above way may be better.
I hope that made sense!
Thank you,
Jennifer

Answer 1

To follow-up, I spoke with Adobe support this morning and they said that I cannot access Workflow variables within Designer (besides those Workflow variables that are already provided).
He mentioned that if I use the hidden fields, that I would need to Render the form each time before going to the User to trigger this to happen. So, I am not sure what I will do just yet. I probably not worry about making the fields readonly for the time being; it was a little extra thought I had and isn't required for our process.
