Upgrade to PrimeFaces 7

[mheppler]

Saw this warning in my server log today while on the create dataset form, and it reminded me to create this placeholder issue for the eventual move to PrimeFaces 7 (released Mar '19).

Info:   autoUpdate attribute is deprecated and will be removed in a future version, use p:autoUpdate component instead.

For a background on this component, see my comment on the PrimeFaces 6.2 Upgrade issue

Accessibility improvements are also a big selling point for the upgrade.

Various components have been enhanced for accessibility related to keyboard support and screen readers.

From the PrimeFaces upgrade guide:

https://github.com/primefaces/primefaces/wiki/Migration-Guide

6.2 to 7.0

Breaking Changes

• Push has been removed. Please use the JSF2.3 socket or OmniFaces now.
• Mobile has been removed in favor of responsive features.
• RequestContext has been replaced by PrimeFaces.current(). RequestContext is still available as PrimeRequestContext but it's internal PrimeFaces API and should therefore be avoided to use.
• autoUpdate attribute of outputPanel, fragment, messages and growl has been removed. Use p:autoUpdate instead.
• OverlayPanel: appendToBody has been removed. Use appendTo="@(body)" instead.
• Button/Link/MenuItem: The url/href attribute isn't automatically prepended by contextPath anymore. Use the outcome attribute for referencing JSF views in the same application or manually prepend url/href with #{request.contextPath}. See OutcomeTargetRenderer: unwarranted and possibly erroneous inclusion of the context path primefaces/primefaces#3506.

Others

• Schedule: Schedule was updated to the newest FullCalender version and therefore some attributes are deprecated.
  • Instead of slotMinutes, use slotDuration now (format: 12:30:00).
  • Instead of firstHour, use scrollTime now (format 12:30:00).
  • Instead of ignoreTimezone, use clientTimezone='local'
  • Instead of axisFormat, use slotLabelFormat

[mheppler]

Regarding the autoUpdate attribute of outputPanel, we need to review the recent additions of this component + attribute combination to editFilesFragment.xhtml (#5565) and dataset.xhtml (#1219). The use of these are filling the server log with message reported in my previous comment.

@mheppler - does this upgrade include Bootstrap 4 or will that be a different effort?

[mheppler]

Like our last effort to update PrimeFaces (6.2 #4220) and Bootstrap (3.3.7 #4219), they can be developed separately, but released together. This was due to both needing to be in sync, using the same version of jQuery.

UPDATE: It appears that the jQuery requirements of our last upgrade efforts would not effect us for this upgrade. With that last upgrade, we bumped up to jQuery 3, and that was the major hurdle. Looking over the migration guides for both, we should not be blocked to upgrade these independently. It is worth pointing out in this discussion that Bootstrap 4 is considered a "major rewrite of the entire project".

[mheppler]

With #6035 and #5977 prioritized and moving through development, anything of note related to primefaces/primefaces#4849 (h/t @PaulBoon) should be relevant to this issue. Which might mean waiting for the release of PrimeFaces 7.1.

Still no 7.1...

Did a quick switch over to 7.0 in my pom, and just watched the compilation errors pile up. Missed the RequestContext breaking change outlined above. And we apparently use Push more than I thought, because I didn't think we used it at all. I'm gonna put this issue back down and let someone a lil more familiar with the java handle it. Sorry.

Reviewed at tech hours. The two major sources of errors seemed to be:

• from org.primefaces.push, which we don't actually use, so is just code that should be easily removable
• org.primefaces.context.RequestContext no longer being available - there is good documentation* on the methods for doing the same things, so should be (several) straightforward changes, e.q. change RequestContext.execute() to Primefaces.executeScript()

*See https://www.primefaces.org/docs/api/6.2/org/primefaces/context/RequestContext.html

And the reference fot the new object:
https://www.primefaces.org/docs/api/7.0/org/primefaces/PrimeFaces.html

There also was a Base64 issue - it looks like we are using the a primefaces class for encoding to a string in https://github.com/IQSS/dataverse/blob/develop/src/main/java/edu/harvard/iq/dataverse/dataaccess/ImageThumbConverter.java (line 531) and we can just change that to something like java.util.Base64.getEncoder().encodetoString().
