Implemented: Rendering widget screen from ftl with the current context
(OFBIZ-12310)
Currently, when you would be rendering a widget screen from a ftl template,
you can use a element screen present on context to call the renderer :
${screens.render("component://common/widget/CommonScreens.xml#countries")}
This rendering is realized with the context present when the object screen
has been initialized.
To simplify the screen call from freemarker template, I implemented a new
macro ofbizScreen
You can call a Ofbiz screen with the ftl context with simple macro
<@ofbizScreen>component://mycomponent/widget/MyComponentScreens.xml#MyScreen</@ofbizScreen>
You can also write
<@ofbizScreen
location="component://mycomponent/widget/MyComponentScreens.xml"
name="MyScreen"/>
Or set a default location on your context
action :
context.defaultTemplateLocation =
"component://mycomponent/widget/MyComponentScreens.xml"
widget :
<@ofbizScreen>MyScreen</@ofbizScreen>
When the screen would be call, the context to rendering the screen would be
use the current context:
<#list contactMechs as contactMech>
<#assign contactMechId = contactMech.contachMechId/>
<@ofbizScreen>component://mycomponent/widget/MyComponentScreens.xml#DisplayContactMech</@ofbizScreen>
</#list>
