Hi Holger,
Great, Thanks for the Edit Forms response, that helps to know where to
focus effort and where to wait for your enhancement roadmap.
I have another question on the logic behind ui:instanceView and how a
form layout is selected for displaying an instance in a form.
Your SWA documentation has a short explanation about the "/mechanism
used by SWA to select the most suitable form for a resource/" using
swa:TitledForm on rdfs:Resource, but I haven't been able to figure the
logic of how the "/most suitable/" form is selected.
I am using a Meta-model to define meta-concepts that I then use in my
Concept model. (BTW I am not sure that I have the Subclassing/Typing
of relationships across the two models correct so that may be a source
of my problems)
Anyhow, I have a scenario that seems to be giving me inconsistent
results (at least from what I am expecting) in the display of forms
via ui:instanceView. For example:
*Meta-Model Class Hierarchy:*
Shape
- Box
- Circle
- Triangle
*Concept Model Class Hierarchy:*
DiagramShape (typeOf Shape)
- DiagramBox (typeOf Box)
- DiagramCircle (typeOf Circle)
- DiagramTriangle (typeOf Triangle)
GraphShape (typeOf Shape)
- GraphBox (typeOf Box)
- GraphCircle (typeOf Circle)
- GraphTriangle (typeOf Triangle)
I have a ui:instanceView defined on the Class of Shape that I want to
apply to all Shapes. Using the Default Application against my
ConceptModel, when I look at the Class nodes for DiagramShape or
GraphShape in the Class Hierarchy my form displays correctly in the
CenterPanel, but when I select any of the subClass nodes I just get
the default form from rdfs:Resource.
You indicate it may be an issue with imports and having the metaclasses
defined in another model. Are you sure the imported metaclasses are
available for the SWP application? Note that the _base argument to the
servlet should contain something like
_base=http%3A%2F%2Frdfex.org%2FwithImports%3Furi%3D...
which instructs the engine to also merge in the imported subgraphs -
identical to ui:graphWithImports(...)
I did notice at one point that when I changed my Class/Type
relationships in my models it had an effect on the form that was
displayed but I haven't been able to replicate it. Is there any way I
can override the built-in logic and give a specific ui:id for a form.
The only thing I can say from the distance is to use ui:id="form" on all
these form views.
