After clicking Action Links, Calendar Prompt is initialised to Today

zoomok

I created a dashboard with 2 dashboard pages and each has date calendar prompts......

Those calendar prompts has Default value as Today (from Repository variable).

In first page, display data lists between today-7 and today (1 week list default) and when I click calendar to any days (for example 2017/05/02), it shows appropriate data list as well..

I added action links to move to second pages with "Navigate to web page" and when I click the list, it move to second page and shows specific records.

But when I move back to first page...the calendar returned to default date today (2017/05/10)..I want to keep '2017/05/02' calendar data.

Only when I click action links..the calendar date is initialised...(I setup prompt scope to "Page")

Anybody can help me?
