Lukasz Lenart updated WW-5835:
------------------------------
Fix Version/s: 7.5.0
> Emit each static script src once per request in the script component
> --------------------------------------------------------------------
>
> Key: WW-5835
> URL: https://issues.apache.org/jira/browse/WW-5835
> Project: Struts 2
> Issue Type: Improvement
> Components: Core Tags
> Reporter: Lukasz Lenart
> Priority: Major
> Fix For: 7.5.0
>
>
> Tag templates that need a framework script include it per instance with
> {{<@s.script src="..."/>}}. A page that renders the same tag N times, for
> example inside an iterator, therefore emits N identical {{<script
> src="...">}} tags.
> Templates that include a static script per instance today:
> * {{simple/inputtransferselect.ftl}}
> * {{simple/optiontransferselect.ftl}}
> * {{simple/updownselect.ftl}}
> * {{simple/combobox.ftl}} and {{html5/combobox.ftl}} after
> [WW-5774|https://issues.apache.org/jira/browse/WW-5774]
> The scripts guard themselves with a window-level flag, so the duplicates do
> not re-bind listeners. They are still redundant markup, and each one is
> fetched or cache-checked by the browser.
> Proposal: let the {{Script}} component remember which {{src}} values it has
> already written during the current request, for example in a request
> attribute, and render nothing for a repeated {{src}}. This removes the
> duplication for every static script at once, instead of handling it in each
> template.
> Raised during the review of [PR
> #2074|https://github.com/apache/struts/pull/2074].
