Naming of view components

I'm trying to implement an application using a fairly typical MVC architecture. Basically I have a number of classes which represent my data, a variety of interfaces (such as tree interfaces, recordset interfaces) which some or all of my data classes implement, and a variety of UI components which are able to view/edit objects which implement certain interfaces. I've run into a bit of a conceptual problem with exactly what the contract of my view components should be. At present I've given them names like TreeModelView and RecordModelView. However, I want to implement a number of different components which view objects of type ITreeModel in different ways. Maybe I should give them names like EditableTreeView, GridView etc to reflect the way in which they are viewed rather than what they view. Any general advice/pointers to information about this would be greatly appreciated!

If I wanted a Tree View to display a Table Model, I'd
write a TreeModel implementation which adapted a
TableModel in to some form of tree (for however that
made sense for the application...).Imagine you have a table like this:
---�---�---�---�---
A � 1 � 1 � 1 | 1
A � 1 � 1 � 1 | 2
A � 1 � 1 � 2 | 1
A � 1 � 2 � 1 | 1And so forth. It's a table, alright, but isn't it better presented as a tree?
A
+-1
� +-1
�   +-1
�     +-1
�     +-2
�   +-2
�     +-1
� +-2
    +-2
      +-1The view is responsible for showing a tree. The model can still be a table. Or the other way around. You need a transformation, but since the transformation is for "optical" purposes only, I think the view needs to do it, instead of creating a whole new and completely redundant tree data model. So the class should be a SomethingTreeView, and not a SomethingTableModelView. That wouldn't give you any info about what would appear on the screen - which is the important part.
Surely you need the view to be able to understand the model, but when it comes back to naming the view's class, I think it shouldn't have the name of the model, rather than the name of its appearance.

JavaFX as renderer for JSF view components

I don;t know if I am asking the right question.
Since javaFX has GUI components, Does sun provide JavaFX as a default renderer for JSF applications. Wouldn't that be cool say I define my view in some standard format and just configure a renderer in some xml and then with a magic, the UI is all based on JavaFX

ejp wrote:
So my question is primarily 'does this make sense?' Yes. I don't see why this wouldn't make sense.
If so, secondly, does this imply I should/shouldn't use Facelets?For now on, it's recommend to start with it. It will be the default supported view technology as per JSF 2.0 and it offers much more advantages than the legacy JSP. Here's a nice document to start with: [https://facelets.dev.java.net/nonav/docs/dev/docbook.html].
Thirdly, what else might I need in the stack?Maybe a 3rd party component library to take out the boring UI and ajaxical work from your hands. For example RichFaces.

Unable to view components in Object Browser & Properties window- Xcelsius

Hi - I have prepared a dashboard which consits of many labels and just a few components. But as I proceed with taking more components on the dashboard ,I am unable to see the components in the object browser and properties window (it is just visible placed on the canvas but not visible in obj browser and Property window)....can any1 suggest the reason and how to proceed ?

HI,
Check in the object browser, whether there is any group element. if all your components are grouped, then they will appear under that group. if you click on any component which is grouped the property window of the group will be displayed.
if you want to see the propery of each individual component, in the object browser-- expand the node and double click the component to see its properties.
hope this helps

Viewing components of BOMs that are components of a top level BOM

Hi All,
Can anyone help with the following issue; in EAM I have an Asset BOM, which has a list of components. One of the components is itself a BOM (a sub assembly) but I can work out how or even if it is possible to see the components of the sub assembly in any reports for work orders usiing the Asset BOM rather than just the name of the sub assembly component. This is in version 12.1.1.
Many Thanks for any help or suggestions,
Paul

If you are on the BOM screen , you can simply go to tools > define subassembly to open the subassembly bom.
If you want similar screen on the Work order scren, you will have to write a quick personalization that opens up the Subassembly bom.
If you want it on a report, you will have to customize it.
The other option is that on your Parent BOM, you can make supply type of the subassembly = Phantom. This will make the subassembly components show up on the Parent's work order as well as on all WIP reports. But it also means, you will not get a demand for the subassembly at all. Instead, WIP/ MRP will explode the demand to the components of the subassembly. Make sure that your mfg. process supports this change.
Hope this answers your question

Excel View web part - multiple named items

Are you able to define more than one named item in an excel viewer web part? I am for instance displaying a power pivot chart with a name chart1 and i also have some slicers added to the sheet in excel. can i show both the chart and the slicers in the
same excel viewer web part?
yaddaimean

Hi yaddaimean ,
No, you cannot define more than one named item in an excel viewer web part. In an Excel Web Access Web Part, you can display one or more worksheets (in Worksheet view) or a named item such as a chart
or an Excel table (in Named Item view).

How do I use the option "table view" in NetWeaver 2004s Query Designer?

Dear,
We have used NetWeaver 2004s Query Designer, We found a strange problem. The option to select table view is not available. It is greyed out. How can you select table view (tabular) in 2004s Query Designer?
I have read the help doc about tabular view of NetWeaver 2004s Query Designer, I check my query, it has only one structure . but the option is still greyed out. I rebuild the query with 3.x Query Designer in tabular view, and reopen it with 2004s Query Designer, So there is a tab named "tabular view" display, but the option to select table view is still not available, and when users view the query result in web , it is still not in tabular view display. So I am confused, is there a bug with NetWeaver 2004s Query Designer?
Please help me. Thanks!

More than one view with iphone SDK.

Hi
I'm trying to make more than one view in Interface Builder and then switch between them in xcode. But I can not figure it out.
I tryed reading guides, watching tutorials, but with no luck.
Can anyone here give me a small tutorial on how do that?

Your best bet is to look through the code (and xib files) distributed by Apple. I was in much the same position a couple of months ago, except my expertise was in JEE. It is really not that difficult to get going. Just a regular Cocoa development book can also help you (it helped me understand how to get going).
Here is what you will start with
ApplicationDelegate - Will be connected by default in your primary xib file. For simple applications that is all you need. If you need multiple views, you can still make the primary nib file you primary view and lay it out as you need. Add methods as appropriate to remove current view and display next view you want.
Xxx.nib - Your primary xib file. Layout out as required. Create a UIViewController and connect to the File's Owner. That connects your controller to the view. Make connections to the view components in the xib file, event handlers etc. It is not difficult, but IMO IB is not very intuitive, though you will get the hang of it very quickly.

Problem with linking PDF documents using named destinations

Linking from one PDF document to another PDF document using named destinations viewed in Reader works great but once the documents are viewed inside a browser environment the link will only open the go to document and will not go to the named destination.
If I make the links using the page number - yes they will work perfectly in the browser. But my problem is that the documents may change in the future and the links may be on differnt pages, so I need to use named destinations to bring me to the page of the PDF they are on.
Any suggestions? I need them to work in IE.
Thanks

You can link to a named destination with a URL. This might work better in
your case... To do it use the following format:

and in hierarchy viewer added row displayed on level one for session then reload page it is ok why shot in level 1
Where I missed? how to Selected rows assign to hierarchy viewer object? thanks juddi

thanks for your reply shay. i am just trying to understand how a dvt HV could render in iPhone mobile browser (eg. iOS simulator) as its a part of ADF Faces components. as a part of mobile development we have only trinidad components available (not HV) and it renders in iOS simulator.
I have tested a HV app (JDev 11.1.1.6) in Safari web browser and it works fine there. Please share your thoughts on this.

Refresh ADF Business Components

I create view(ADF business components) with my sql statiment
select e.*,d.* from scott.emp e, scott.dept d where e.deptno=d.deptno
on my first page JSP I drop ReadOnly table
on my second page JSP i drop InputForm for edit.
and so
I run my project, on first page have the button "Edit" which is bound my JSF Navigation Case with second page.
I try edit emp.DeptNo and commit change. When I back on first page i see that emp.DEPTNO changed but dept.DNAME not changed.
How I can refresh my first page that see all changed?

Hi Frank!
I use JDeveloper 10.1.3 EA1.

Plant specific component views in BOM

Hi,
I have 2 Plants say, A and B. I have a Product say P which has several components C1, C2, C3 ...
I wish to create a single centralized BOM with all the components. However, Plant A should be able to view components C1 and C2 only whereas Plant B should be able to view components C2 and C3 only.
When I make changes in the centralized BOM, the change should be reflected in the respective Plant views accordingly. I do not want to create BOMs individually at each Plants for the Product.
I tried using Group BOM and Plant Assignment, but not able to restrict component visibility as required above. I tried using Effectivity Filter using Effective Parameter as Plant. But doesn't seem to work ...
Is there any simpler way ...?
Thanks.
Raj

hi
is plant A using only two components C1 &c2
is plant B using only c2& c3
plz let clear your requirement ,why its needed
create alternative bom using authorisation key
probably solve your problem
