> 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.
