10g Preview: No way to rename view link usages in AM

10g Preview (9.0.5.0.0 Build 1375), Win2k SP3.
I generated the entity objects, view objects, associations, and view links from my DB structure. I created an application module with the default data model from the view objects and view links.
I then renamed all of the view links using the Rename View Link dialog. The AM's xml file was correctly updated with the new names of the underlying view links, but the view link usages retained the old names.
There does not appear to be a convenient way of renaming the view link usages in the AM. The workarounds are either to deconstruct the data model and then reconstruct it, or to manually edit the .java and .xml files.
I would like to see, at minimum, the ability to rename the AM's usages via a right-click menu in the Structure pane. This would affect both view object and view link usages. Currently the only option available in the right-click menu is to edit the underlying business object, not the usage. It also would make sense to allow view link usages to be renamed from the Data Model page of the AM wizard.

That worked beautifully. I didn't have the property inspector open originally, so it's nice to know there is a way to rename usages after all.
I wonder if there's a usability issue here though... maybe it's just me, but with the ability to rename some things via the right-click menu in the navigator pane, it seemed natural to look in the very similar structure pane for the same sort of functionality. Now there's a third place to look. Perhaps if the right-click menu in the structure pane simply had a "Properties..." entry or something similar that brought focus to the Property Inspector, it would help the user understand that there's another place to try to make the desired changes.

10g Preview: BUG: Infinite loop renaming entity attribute

9.0.5.0.0, Build 1375, Win2k SP3.
BACKGROUND:
After attempting to rename an EO on which a VO was based I received an error that indicated the VO was dependent on the attribute to be renamed. I removed the VO attribute from the VO's attribute list and saved the changes. I then brought up the Entity Object wizard where I attempted to rename the attribute.
When jdevw.exe is used to launch the IDE, the renaming action results in the IDE hanging. When jdev.exe is used, the console prints the following stack trace and the IDE gives a StackOverflowError.

How to rename a View Link in a data model?

In JDeveloper 9.0.3, I create a simple BC4J project with a master and a detail. The business components are properly created.
When I try to design the data model for the module, I am able to link the view for the master and the view for the detail, there is no problem to rename the view objects that I select in my data model, but I found no way to rename the view links used between the view objects.
I always get an automatically generated name, like "FkForeignDetailLink1". This is what I see in the data model, and also in the structure of the module, in the "View Link Members" section.
I am able to modify the properties of this view link, but not its name. Am I missing something?
TIA

to clarify... In the AM wizard, you are trying to rename the instances of view objects and view links?
If so, you are right, there is no way to rename view links on that panel. We are working on a better way to do that for the next release. The only way I know of to rename the view links is to shut jdev down and edit the XML for the application modele. This can be dangerous if you get it wrong, so make a backup before attempting this. The hint with renaming things OUTSIDE JDeveloper, I already know, but I don't like much.
As for the AM wizard, I just noticed that I cannot do it inside. But that's no problem for me, as lots of details cannot be done inside the wizard, but there is a way to customize them afterwards. My real problem is that didn't find ANY way of doing it.
A question for you if I may. Why are you renaming the view link instances? I though most users would use the detail view instance directly. The detail view instance would in turn look up the appropriate view link into, what ever its name was. The only place where I saw the bad view link names displayed in JDev was the Structure pane of the AM, under View Link Members. But there is no way to modify them there. As for the detail view instance, I didn't find a place to get to the view link at design time (in 9.0.3.988).
Could you be more precise, please?
Thanks again,
Adrian

Change View Link Name in BC4J

I wonder if there is a way to change the name of a view link member in a application module, in a BC4J project?

Hi Song,
I assume that renaming your View Link (the actual component) is not an option for you.
If you just want to rename the View Link instance:
1. Shut down JDeveloper.
2. Find the file YourAppModule.xml
3. Open the file in your favorite text editor.
4. Find the <ViewLinkUsage> tag that contains the View Link Usage you want to change.
5. Change the "Name" attribute.
6. Save the file, exit, and restart JDev.
Hope this helps.
Best,
Avrom

When previewing images by clicking on the thumbnail in an Event for example, I've been finding that many images preview in a 'zoomed in' way so only a small part of the photos is previewed in a highly magnified view.

When previewing images by clicking on the thumbnail in an Event for example, I've been finding that many images preview in a 'zoomed in' way so only a small part of the photos is previewed in a highly magnified view.
Initially I could find no cause. Then I tried right click - Edit and on the affected images, always get this warning:
"Image Cannot Be Edited - This photo was previously edited with another application or with an early version of Iphoto. Duplicate this photo to edit it." and a "Duplicate To Edit" Button is displayed.
The external Editor defined for iPhoto is Adobe Photoshop Elements.
Now, I reckon the MUST be others out there affected by this same apparent Preview bug, yet my searches have not revealed any answers. Also seems impossible to find a contact number for adobe???
Thanks

Is there a way I can view/manage devices linked to my iCloud account?

Is there a way I can view/manage devices linked to my iCloud account? I know how to view the devices linked to my iTunes account, but I am not sure if this is possible to see with an iCloud account.

You can't, except by seeing if they are using services associated with the account. You could, for example, launch Find My iPhone on iCloud.com to see what devices appear (which obviously wouldn't show devices not using Find My iPhone). Similarly, you could go to Settings>iCloud>Storage & Backup>Manage Storage to see what devices appear on the Backups list (which won't show devices not using iCloud backup).

Problem with running Applets in JDEV 10G Preview

Our Jdeveloper project has a default run target which is an Applet HTML page.
Sometimes when a you click Run/Debug the project runs in Applet Viewer and sometimes it spawns an OC4J process and runs it in the container. It seems the execution of our project has a mind of its own. You can run/debug the same project on different developer PCs and have different execution behavior.
How do you configure the execution environment for applets?
If possible, it would be nice to be able to create multiple execution profiles so that we could have this applet run in OC4J sometimes and in AppletViewer other times. But it does not seem like you have control of this under the project properties.
Thanks,
Paul Manning

Hi Paul,
In the 10g preview, the code that launches applet viewer has first crack at whether it should "run" your html file. If that code thinks it should not launch applet viewer, then the code that launches OC4J gets a chance. The applet viewer launcher looks at the contents of the html file and looks for the <applet> tag. Is it possible that the contents of your html file is changing in such a way that my applet viewer launcher code isn't able to find the <applet> tag? If so, can you possibly send me your html file, or describe the applet tag(s), so that I can improve my side? I'd really appreciate it.
In the near term future (the 10g release), when the run target can be started in different ways (like your applet html), the user will get to choose which way when he/she clicks run/debug. If you use the context menu, the run and debug items will lead to a pull-right submenu that lists all the choices. However, if my applet viewer launcher code doesn't find the applet tag in your html file, you won't see applet viewer in the list of choices.
In the long term future we will support real multiple execution profiles.

TP4 ADF BC [BUG] view link are not updated after database synchronization

I have a table with a recursive relationship.
By mystake, I created a recursive foreign key for the same attribute (deptid->deptid instead of deptid->parentdeptid).
I generated entity, view and application module from this schema.
When compiling, errors was produced indicating the problem.
I corrected the problem in offline database, generate the changes into the database successfully.
I ask to synchronize the entity with the database, the changes was identified correctly and a new association was created.
First remark: the old one still there and it was necessary to delete it and rename the new generated one (to be consistent with other name). May be an option to overwriting the old one will be more pleasant, may be asking if the new one has to replace an existing one and show a list of existing ones.
Regenerating the association was correct and one error was removed when compiling again. The error on the view link still there.
I would like to delete the assoc and recreate it from the entity assoc but it was not possible easily because the view link is used in the application module !!!!
It will be nice to permit to regenerate an existing view link from an entity association without deleting it.
May be it is a better way to synchronize ? I would be very interesting to know how to achieve it as the best !

Was the inability to have the synchronization remove the key specific to the existing association's being self-referential, or if your initial association was from DeptId to some other attribute (which you then corrected) would the synchronize have fixed the problem?
The simplest way to achieve what you want given existing features would be to have delete the view link instance, view link, and association, follow by resynchronizing (I believe), then recreating the viewlink and adding back the view link instance.

View link in front of Filter used is giving error

Hello Experts,
Please help me in this:
I have a report made in OBIEE 10g in which ,below the report the filter used in report are shown.
In front of these filter there is a link "View" which when I click it does not view the filter.
As in my case its like below:
Filter1
and filter2 are prompted view
and filter3 are prompted view
and filter4
so when i click the view link above it gives me an error as : 'sawCommandToURLlmpl' is undefined.

Not familiar with the error message, but here are some general ideas you can check.
I believe you are referring to "saved filters" that when displayed in Filter View, have that "View" link at the far right. The link is automatic and points to where the filter is saved. Barring any configuration problems, check to see if the saved filters were saved properly. By this I mean that they were saved in a location that can be viewed by the user who would click on the link. If the permission doesn't allow the connection back to the source, you will get an error. Hope this makes sense.
Other questions to ask and answer:
1) Do all saved filters behave this way (i.e., with an error message)?
2) Do the reports and filter views work as expected when run as Administrator with full access?
3) Does the problem exist in all browsers? Versions?
Good luck.

View Link between two query views

Hi is it possible to create a view link between two views having the where clause bind variables.
How you set the bind variables at the run time for the View objects. It is giving hard time for me to use the Master view in the XmlData bean to generate the Xml document.
I am able to set the Master views bind variables, but for view link destination view
where clause bind variables are not able to set ( link object link condition bind variables are binded run time but the views where chause bind variables of destination view are unable to setand bind)
Thanks
null

Easiest way to do this is to add additional transient attributes to your master view object, and then include those additional transient attributes in the list of source attributes for your view link. This way, you can get BC4J to automatically refer to their values with no additional code on your part.

ADF BC: both ID and view link object as getter/setter in row impl

I notice something when generating the row implementation of VO that have links to other VO. I can't seem to find the logic behind it...
Following model:
users( id, address_id,name,firstname,...)
address(id, street,number,...)
their is an assosiation between the UsersEO and the addressEO. Their is also a view link between the UsersVO and the AddressVO based upon the assosiation of the EO's.
When we create the row implementation of the UsersVO we find a getter and setter for both the address_id as well as the address row object.
Why is this?
We have this issue because i added the UsersVO and the addressVO to the app module but i haven't added the link to the appModule but when i create the SDO from the appModule, the Users has both the address_id as the address row object.
THis does not seem to make sense. How do you use it correctly? Do you just need to set the address_id and can leave the row object null or do they both need to have the same? What if you set the address_id to 1 but the id in the address row object is set to 5...
How do the databindings handle these things?
To me it seems more logical that the VO only has a getter and setter for the address object and handles the address_id in the background according to the values in the address object.
Can someone explain me why this is implemented this way and how to handle it correctly?

Why is this? The definition of the VL allows you to optionally generate accessors for the underliying VOs, i.e. getAddressVO() in the UsersVO and getUsersVO() in the addressVO.
We have this issue because i added the UsersVO and the addressVO to the app module but i haven't added the link to the appModule but when i create the SDO from the appModule, the Users has both the address_id as the address row object. You should add the addressVO to the AM using the VL instead and not by itself.

As mentioned above, once you add the addressVO to AM using the VL, the framework will take care setting the value of the row objects accordingly.

Is there a way to rename all photos in a folder?

Is there a fast way to rename all the photos in one folder e.g. I have diffreent folders say "wedding" and "birthday" with alot of photos in each. Is there a way to rename all photos in the folder to the same name like all called wedding?
Also when i open photos they automatically open with preview, do I need to impost them into iPhoto or should they just automatically save there?
Tracy

Tracy
Are these photos in iPhoto? If so, then use the Photos -> Batch Change command.
IF not then you can use a batch file renamer such as Name Mangler
iPhoto is a database and can only show pics that have been imported to the DB.

Bug in bc4j?, view links at runtime, multi table relationships, accessor name

The following seems like a bug in the business components framework
to me:
To make things simple, I will use view objects aV, bV, cV,
corresponding rows aR, bR, cR and row iterators aI (not used though),
bI, cI.
I create two view links from aV to bV and from bV to cV at runtime,
with the accessor names "Bs" and "Cs".
ViewLink a2b = createViewLinkBetweenViewObjects(..., "Bs", ...);
ViewLink b2c = createViewLinkBetweenViewObjects(..., "Cs", ...);
First of all this code works perfectly fine:
ViewObject aV = a2b.getSource();
ViewObject bV = a2b.getDestination();
ViewObject cV = b2c.getDestination();
while(aV.hasNext())
Row aR = aV.next();
System.err.println("aR");
while(bV.hasNext())
Row bR=bI.next();
System.err.println(" bR");
while(cV.hasNext())
Row cR=cI.next();
System.err.println(" cR");
Using the accessor name "Bs" at the first level is ok, too:
ViewObject aV = a2b.getSource();
while(aV.hasNext())
Row aR = aV.next();
System.err.println("aR");
RowIterator bI=(RowIterator)aR.getAttribute("Bs");
while(bI.hasNext())
Row bR=bI.next();
System.err.println(" bR");
HOWEVER, USING THE ACCESSOR "Cs" AT THE SECOND LEVEL OF THE MULTITABLE
RELATIONSHIP IN THE FOLLOWING CODE, GIVES ME AN EXCEPTION
oracle.jbo.NoDefException: JBO-25002: Definition Cs of type Attribute
not found. THE SEEMS LEGAL USAGE OF THE ACCESSOR "Cs" TOO ME THOUGH,
THEREFORE MY SUSPICION OF A BUG.
ViewObject aV = a2b.getSource();
while(aV.hasNext())
Row aR = aV.next();
System.err.println("aR");
RowIterator bI=(RowIterator)aR.getAttribute("Bs");
while(bI.hasNext())
Row bR=bI.next();
System.err.println(" bR");
RowIterator cI=(RowIterator)bR.getAttribute("Cs");
while(cI.hasNext())
Row cR=cI.next();
System.err.println(" cR");
(By the way, could make your window for filling in the message a little bit wider,
making it easier to cope with the line breaks).
Feedback is appreciated.

Your results are as expected per the imlementation. Basically you've established (two) ViewLinks between two sets of two instances of VOs.
Now you try and get an accessor to return a set of details. You need to establish a link between that detail set and it's details to use the accessor on the second detail to get the desired results. Basically you've to establish the chaining between appropriate instances of VOs and not just the outer VOs or VO members of your AM.

I created a static view object called StaticDepartments with the data from the DEPT table, but typed in statically.
I created a normal, entity-based EmpView VO over an Emp EO.
I created a 1-to-* view link between StaticDepartments and EmpView based on the Deptno attribute.
I added the master/detail to the AM's data model and tested, and it worked ok.
What's different about the way you're creating the view link here?
