response missing after going to a different page

[xcompass]

if I go to the second problem, and then click back to the first problem, it looks like my answers have been deleted. If I hard-refresh the page, I get back to the answer state.

@xcompass Can you explain what you mean by the 'second problem' and 'first problem'? Are these on different units? And when you say 'click back' do you mean using the browser back button, or the lms back arrow?

[richardtape]

To reproduce: LMS. Have two units. Have a component on each (one should be UBCPI, the other is unimportant). Submit an answer to the first part of the UBCPI flow (but not a revised answer) and then switch to the other unit using the edX control bar at the top, then switch back to the UBCPI component. Your submitted answer and rationale do not show. However, if you do a hard refresh, they are visible.

Expected behaviour: On returning to the UBCPI component, your submitted answer should show (just like it does if you do a hard refresh)

Issue still encountered during recent round of student usability testing. Use case: student is on second step and begins typing in revision form, accidentally navigates away using the edX control bar at the top, returns to find exercise has been reset to first step.

Will revise and call assignData with the latest received persistedData

ubcpi/ubcpi/static/js/src/ubcpi.js

Lines 120 to 126 in ff69bbb

	// Assign data based on what has been persisted
	var persistedDataObject = get_data().then( function(persistedData) {
	if ( persistedData.answer_original !== null ) {
	assignData(self, data);
	}
	});
