Hi,
JBoss tools eclipse plugin for JSF development provides visual representation of UI and
provides a mechanism to drag and drop JSF component (Core JSF and Richfaces) on Visual
editor.
We are trying to get a similar feature where user should be able to drag and drop managed
beans properties on Visual editor, which should create the corresponding JSF component
(depending on the data type of the element) on visual page editor.
For e.g. if user drags an element (of data type String) and drops on the VPE then a pop up
should come up where he selects the type of input component he wants and say ok. This
eventually will add the code corresponding to JSF (along with databinding) on VPE.
We observed that "Web Projects" view (which is provided by JBoss) lists all the
managed beans and user can drag and drop bean properties on Visual editor. When the user
drops the element on VPE then value binding gets added to it.
Is there a way to add a hook between these (Web projects plugin and VPE plugin) to achieve
our objective.
Or is there some other mechanism to achive this (may by extending any plugin etc.).
Regards,
Kaushal

At present, dnd to VPE does not provide an extension point. We have implemented three
cases of dnd: items from Palette, bean attributes from Web Projects, files from Package
Explorer. When a file is dropped, a wizard is displayed with choice of relevant tag to be
inserted (e.g. for xhtml it is ui:include and s:decorate; all available options are
described in code). A similar wizard could be displayed when a bean attribute is dropped.
Then, we have to provide an extension point to allow adding proposals for custom
components and bind them to bean attribute type. Please add a feature request to JBoss
Jira for JBossTools project.
Alternatively (or in addition), should we provide an opportunity for a user to bind data
types and components in preferences, so that on a bean attribute drop, the wizard would
read suggestions from preferences rather than from added plugins? Not many users would
bother to write plugins to extend a feature, it is easier to customize it in preferences.
String bean attribute can be bound to most attributes of most JSF components, should
wizard try to show them all, or only some 'favorite' options?

Suggesting preferences, I meant only the drop of bean attributes from Web Projects view,
that is, objects well known for JBoss Tools. Preference could map Java type of bean
attribute to {tag library uri + tag name + attribute name to put EL in}, or even to a
snippet where user will specify all sub components. Then the drop would be processed in
the same way as it is for a Palette item, with the only difference that a specified
attribute will be prefilled by EL. Maybe for common Java types like String this
functionality will not be of greate advantage, but for specific cases like
List<Person> user might find quite helpful to have a nice snippet and apply it with
one mouse drop.
There is now no extension point for registering new implementation of IDropCommand. We can
readily add such a point, but I think we may allow to bind it only with a new transfer
data type to prevent it from conflicting with existing IDropCommand implementations. In
this way, dnd from some new view may be supported. For currently supported transfer data
types, we can provide extensions through the existing implementations. For example, for
the drop of bean attributes from Web Projects view, PaletteDropCommand may request
extensions if they have for a given bean attribute to provide a snippet (or choice of
snippets) and/or wizard to customize it (then the above-mentioned usage of preferences is
an example of implementation of that extension).
