is it possible to retain local variable or rule input values after which gets refreshed during Submit action and use them before submit action gets completed?

List of task is represented from which I can deactivate particular required task 

Before deactivating task, I need to check if that task is present as precedent task for any other task or that itself should not have any precedent task

currently after clicking on deactivate icon I am getting validation msg but its for all task, but i want it for only particular task that has been used as precedent task

I need to give show When condition to validation msg for that I need task name, but due to submit link used for deactivate icon all values saved are getting refreshed

is it possible to retain that values and used to show validation msg
