[GregP]

Added code to clear out Search box text, fixes 2 BZs. Keeps Search text while navigating through accordions on a page, but clears out Search text when button is clicked and renders unfiltered data display.

@GregP i think this should be outside of if @explorer check

@h-kataria Ready for review.

@GregP do we need to only clear search text for Infrastructure VM explorer, wondering if it will just work for all explorers without this if condition

[GregP]

The issue is we do not yet set @explorer value to true when we process this clear text code. Timing issue at this point. But, yes, eventually, the preference is to provide app wide fix. Need more analysis before enabling all explorer pages.

[GregP]

@h-kataria Refactored code to pass along explorer. Back in [WIP] mode for now to see if this change works for application wide explorer pages.

@GregP, @h-kataria : I think that this PR breaks the clear search button in the Hosts.

[GregP]

@martinpovolny @h-kataria Per discussion, this fix was only intended for Explorer type pages. New code "funnels" all Search Text clearance user requests though a new central point, but only Explorer type pages then clear the search text box and reload page contents. All other pages, non Explorer type including Hosts page, act same way they used to prior to this fix: search text is cleared, but page contents not reloaded automatically. Hope this helps and resolves the issue/concern.
