better performance!
--------------------------------------------------------------------------------------------------
Key: WW-2077
URL: https://issues.apache.org/struts/browse/WW-2077
Project: Struts 2
Issue Type: Improvement
Components: Component Management
Affects Versions: 2.0.10
Environment: All
Reporter: Felipe Rodrigues
I'm thinking about open an issue to make put parseWidgets: false on djConfig
initial load. This would improve the performance so much.
The fact is that dojo walk through each DOM node in a document looking for
widgets to parse, so it makes the footprint very slow.
The solution is to tell to dojo what are our widget, based on widget id. A
simple solution would be put a line in each ftl template to render some dojo
widget. Something like that in FTL:
<div dojoType="struts:BindDiv"
<#if parameters.delay?exists>
delay="${parameters.delay?c}"<#rt/>
</#if>
<#if parameters.updateFreq?exists>
updateFreq="${parameters.updateFreq?c}"<#rt/>
</#if>
<#if parameters.autoStart?exists>
autoStart="${parameters.autoStart?string?html}"<#rt/>
</#if>
<#if parameters.startTimerListenTopics?if_exists != "">
startTimerListenTopics="${parameters.startTimerListenTopics?html}"<#rt/>
</#if>
<#if parameters.stopTimerListenTopics?if_exists != "">
stopTimerListenTopics="${parameters.stopTimerListenTopics?html}"<#rt/>
</#if>
<#if parameters.refreshOnShow?exists>
refreshOnShow="${parameters.refreshOnShow?string?html}"<#rt/>
</#if>
<#if parameters.separateScripts?exists>
scriptSeparation="${parameters.separateScripts?string?html}"<#rt/>
</#if>
<#include "/${parameters.templateDir}/ajax/ajax-common.ftl" />
<#include "/${parameters.templateDir}/simple/scripting-events.ftl" />
>
<script>djConfig.searchIds.push("${parameters.id}");</script>
>From what I've seen this would be a little change that would make us improve
>the performance of Struts2.
