Matt Cooper commented on TRINIDAD-1930:
---------------------------------------
Other changes for consistency with other components in the trh namespace:
UIComponent class: org.apache.myfaces.trinidad.component.html.HtmlMeta
Component type: org.apache.myfaces.trinidad.HtmlMeta
> Ability to easily create a meta tag

> Issue Type: Improvement

> Reporter: Matt Cooper

> Ability to easily create a meta tag (e.g.
> http://developer.apple.com/library/safari/#documentation/appleapplications/reference/safarihtmlref/articles/MetaTags.html
> or http://www.webmarketingnow.com/tips/meta-tags-uncovered.html ) via a new
> trh:meta tag.
> Currently it is quite tedious to create a meta tag out of a component:
> <tr:document ...>
> <f:facet name="metaContainer">
> <tr:group id="metaContainer">
> <tr:outputText escape="false"
> value='<meta name="viewport"
> content="width=device-width">'
> id="metaTag1"/>
> <tr:outputText escape="false"
> value='<meta name="apple-mobile-web-app-capable"
> content="yes">'
> id="metaTag2"/>
> <tr:outputText escape="false"
> value='<meta http-equiv="refresh"
> content="2;url=./test/index.jspx">'
> id="metaTag3"/>
> </tr:group>
> </f:facet>
> </tr:document>
> It would be much better if we had a trh:meta component that looked like this:
> <tr:document ...>
> <f:facet name="metaContainer">
> <tr:group id="metaContainer">
> <trh:meta name="viewport" content="width=device-width"/>
> <trh:meta name="apple-mobile-web-app-capable" content="yes"/>
> <trh:meta name="refresh" nameType="http-equiv"
> content="2;url=./test/index.jspx"/>
> </tr:group>
> </f:facet>
> </tr:document>
> So I would like to see a new trh:meta component that has an API like this:
> Tag name: <trh:meta>
> UIComponent class: org.apache.myfaces.trinidad.component.core.CoreMeta
> Component type: org.apache.myfaces.trinidad.CoreMeta
> The meta component generates an HTML meta tag and is intended to be used
> inside either the trh:head tag or the document component's metaContainer
> facet.
> Events
> Type Phases Description
> org.apache.myfaces.trinidad.event.AttributeChangeEvent Invoke
> Application, Apply Request Values Event delivered to describe an
> attribute change. Attribute change events are not delivered for any
> programmatic change to a property. They are only delivered when a renderer
> changes a property without the application's specific request. An example of
> an attribute change events might include the width of a column that supported
> client-side resizing.
> Attributes
> Name Type Supports EL? Description
> attributeChangeListener javax.el.MethodExpression Only EL
> a method reference to an attribute change listener. Attribute change events
> are not delivered for any programmatic change to a property. They are only
> delivered when a renderer changes a property without the application's
> specific request. An example of an attribute change events might include the
> width of a column that supported client-side resizing.
> binding org.apache.myfaces.trinidad.component.core.CoreMeta Only EL
> an EL reference that will store the component instance on a bean.
> This can be used to give programmatic access to a component from a backing
> bean, or to move creation of the component to a backing bean.
> id String No the identifier for the component. The identifier must
> follow a subset of the syntax allowed in HTML:
> * Must not be a zero-length String.
> * First character must be an ASCII letter (A-Za-z) or an underscore ('_').
> * Subsequent characters must be an ASCII letter or digit (A-Za-z0-9), an
> underscore ('_'), or a dash ('-').
> rendered boolean Yes whether the component is rendered. When
> set to false, no output will be delivered for this component (the component
> will not in any way be rendered, and cannot be made visible on the client).
> name String Yes the name or http-equiv attribute of the meta attribute
> (see nameType)
> nameType String Yes "name" or "http-equiv" indicating which kind of
> name attribute is desired ("name" is the most common attribute but some older
> meta tags need "http-equiv")
> content String Yes the content of the meta attribute
