1) ace:ajax > Advanced: values rendered on page are not updated when dragging the cursor; the update appears to only work once, then values displayed return to initial values and they can no longer be changed (deltaSubmit=true specific).

Does this occur with the default configuration for the Ajax-Advanced demo, without changing any of the option checkboxes?

2) ace:dateTimeEntry:
> Ajax Submit: selected date is no longer updated on page after unchecking "Display as Popup" checkbox (deltaSubmit=true specific).

Does the failure occur if you don't dynamically change the demo? For example, if you uncheck "Display as Popup", the reload the page, then perform the demo test?

3) mobi:dateSpinner (Date and Time demo, iOS10/iPad):
After changing "Use native" to true or false, the date output value is not updated when changing dates in the component (deltaSubmit=true specific). No issues on desktop.
It doesn't appear to be an issue with the time value, that is updated anytime after toggling 'use native'=on/off.

Does the failure occur if you don't dynamically change the "Use native" attribute? For example, if you check/uncheck "useNative", then reload the page, then perform the demo test?

1) yes, the failure occurs with the default page, only by dragging the cursor to a new position more than once.
2) no, the failure occurs only if unchecking "Display as Popup" before changing dates in dateTimeEntry.
3) no, the failure occurs only if checking/unchecking "Use native".

Okay, I don't think we should worry about the #2, #3 failures since they are not likely real-world usage scenarios that need to be supported. Let's limit the JIRA to #1 then.

Force the rendering of the slider (by adding @this to the render attribute) entry on postback to ensure the server side DOM is updated with the latest value of the slider. By doing this the delta submit can properly calculate the previous parameters off the old document.
