Description
Make it possible to specify a default value for attribute@cascade.
I'm writing definitions for a legacy project and we don't have the luxury of a flat template that directly inserts each defined attribute.
To have to specify cascade="true" on every put-attribute seems excessive verbosity.
One solution would be to add a boolean attribute cascadeAttributes to Definition.
For example:
<definition name="myapp.homepage" template="/layouts/classic.jsp" cascade-attributes="true">
<put-attribute name="header" value="/tiles/banner.jsp" />
<put-attribute name="menu" value="/tiles/common_menu.jsp" />
<put-attribute name="body" value="/tiles/home_body.jsp" />
<put-attribute name="footer" value="/tiles/credits.jsp" />
</definition>
instead of today's
<definition name="myapp.homepage" template="/layouts/classic.jsp">
<put-attribute name="header" value="/tiles/banner.jsp" cascade="true" />
<put-attribute name="menu" value="/tiles/common_menu.jsp" cascade="true" />
<put-attribute name="body" value="/tiles/home_body.jsp" cascade="true" />
<put-attribute name="footer" value="/tiles/credits.jsp" cascade="true" />
</definition>
Implementation:
+ add to FillDefinitionRule.begin()
definition.setCascadeAttributes("true".equals(attributes.getValue("cascade-attributes")));
+ change in PutAttributeRule.begin()
definition.putAttribute(attributes.getValue("name"), attribute,
"true".equals(attributes.getValue("cascade")) || definition.getCascadeAttributes());
+ add to Definition the getter and setter methods: getCascadeAttributes and setCascadeAttributes
