---------------------------------------
Summary: Provide API to discover location of document that
contains tag definition for a given component
Key: TRINIDAD-2397
URL: https://issues.apache.org/jira/browse/TRINIDAD-2397
Project: MyFaces Trinidad
Issue Type: Bug
Components: Components
Affects Versions: 2.0.1-core
Reporter: Prakash Udupa
There are custom tags and components that insert other dynamic contents (i.e
subtree of components) into the component tree. The tags for such dynamically
added components come from a document fragment that is different from where the
inserting component / tags come from. For example in Oracle's ADF component
library, there are "region", "pageTemplates" and "declarativeComponent" that
does such dynamic includes.
There is often a need to know the document where the corresponding tag is
defined for a given component. A couple of usecases are:
1. Browser based "page editor" or "Designtime @ Runtime" kind of products where
they will need to change the tags in the document when a component is
customized / edited at runtime.
2. Ability to store any runtime customizations for components against the
document where its tag belongs. (For example. when the columns of dynamically
added table is reordered)
The inserting tags / components and the inserted components would be used best
to determine the location of the fragment document that they include / or where
they came from. We need to provide some hooks where the authors of such tags /
component are able to provide the URL for the documents given the components.
This enhancement asks for providing an API that provides URL for such
documents, and also to publish the necessary hooks that tag / component authors
can implement when then the URL providing API can use.
