BACK Button to undo multiple actions

Sat, 17 May 2014 18:12:37 GMT

Hi All,

I am facing a problem on BACK Button.

In general,the BACK function work well after making selections on listbox or making changes on any variable without any triggers.

However, if there are variables with multiple actions behind the variables to be triggered, the BACK function can't work property once after changes on variables. For example, when there is a change on variable with 3 actions behind to be triggered, I need to press 3 times the BACK button in order to change back the variable and get all thing look like before the variable get changed.

Attached QVW is the scenario on my case for your reference.

Thanks in advance for any help.

Yes. The back button works.

However, when the dashboard has variable event triggers.

In my example, there are 3 actions created on the variable 'vIncludeCat'. i.e, when there is any change on the value of the variable (e.g from 'Yes' to 'No') , the variable will trigger 3 actions (=3 steps taken on dashboard).

That mean, if I want the dashboard go back to the status before I made changes on the variable, I need to press the BACK button 3 times.

Under general situation (make a selection on list box), click the BACK button 1 step back is fine.

But, how can I click the BACK Button 1 time to go back 3 steps while sometime it only need to go back 1 step??

How can the back button know how many steps it should go back??

Many thanks for your help!

Hi.

The back button works this way.

Each action is selection, so it's stored separately in history.

Change the logic or try to make your own 'back' button that knows the number of steps backward.
