Subclass webutil object group problem

Hi,
I am using 10g form.
I download the webutil demo and got a form called WU_TEST_106 in which there is
a object group called WEBUTIL.
Then I create a new form and drag the object group WEBUTIL of the form
WU_TEST_106 to the object group of the new form and choose 'subclass'.
When I check the content of the WEBUTIL data block in the new form, there
is no items there.
There should be some bean area such as WEBUTIL_FILE_FUNCTIONS and
WEBUTIL_HOST_FUNCTIONS etc.
Anyone can help ?
Ivan

Do not subclass WEBUTIL from another form. In folder <DevSuiteHome>\forms there should exist file webutil.olb. Open this file directly in Form Builder using
File | Open
and subclass the objects contained within.

Problem with subclassing of object groups

Hi All,
I've a template form which i use to create new forms (for creating our own toolbar, triggers etc).
When i subclass the object group of template form to my new form, it creates form level triggers, toolbar data block etc in my new form.
One of the trigger being subclassed is ON-ERROR form level trigger.
The code inside this trigger is std_blk_on_error; // this procedure is a program unit written by us.
But, when i try to compile this new form, it gives me internal error (deplu 3) on this trigger.
Error 0 at line 1, column 1
statement ignored.
Can any one please help me with this?
Regards,
Navnit

std_blk_on_error; // this procedure is a program unit written by us.or is the code
std_blk_on_error;and this fails on all Forms ?
and it works if you remove this trigger from the object group ?

Added webutil object group with JDAPI - adjust the webutil block sequence ?

Hi all,
I'm using the JDAPI to subclass in the webutil object group into Forms in an application. Annoyingly, the webutil block becomes the first block on the Form - which means on some Forms it displays on startup. Is there anyway (programmatically using JDAPI) that I can move the block the end of the block list after I've subclassed in the object group ?
TIA
Steve

Hello,
move
void move(JdapiObject nextObject)
Reorders an object with respect to its siblings in the collection it belongs to. This is similar to using drag and drop in Form Builder to move a block in a list. This method represents a way to do the same thing programmatically. For example, if you want a block appear immediately before Block5 in a list, you pass the object representing Block5 as the nextObject argument.
Pass null to this method to move the object to the end of the list. If the specified object and the next_object do not share the same owner, or do not have the same type, the method throws an exception.
You cannot use this method to move objects between parents. For example, it cannot be used to move an Item from one Block to another. If you want to move an object from one parent to another you will have to do something like:
// to move 'itmA' to be positioned before 'itmB' in block
// 'blkB' (when 'itmA' is in another block)
// copy itmA into a new parent (blkB) using same name
Item newItmA = itmA.clone(blkB, itmA.getName());
newItmA.move(itmB); // move new item relative to itmB
itmA.destroy(); // delete original object
itmA = newItmA;
Parameters:
nextObject - the object next to which the specified object is to be moved.
Throws:
JdapiException - if you attempt to move an object next to an object that does not share the same owner or is not of the same type.

Attaching the WebUtil object group to a form

Hi. I'm hoping for some help on how to attach the WebUtil object group to a form. I go to the Object Groups node in the object navigator and click the '+' button, but I'm not prompted to attach .olb files. How do I do this? Without it attached I'm receiving the message "The WebUtil object group is not available in this form. WebUtil cannot work." when I run my application. Thanks in advance.

Okay I opened the .obl and it appears under the Object Libraries Node. Then I double-click on the Object Groups node in my form and it simply creates a new object named OBJECT_GROUP100. I can't seem to drag and drop from the Libraries Node to the Object Groups node in my form. It just shows a circle with a line through it indicating that I can't drag it. Any suggestions? (Sorry, I've not done this before).

Problem subclassing an object group from an object library

Hi
I've created an object group using Forms 6i (can't tell you the exact version just now) containing a number of objects, including a couple of alerts, a couple of data blocks, canvas, window, program units etc. I've saved the object group into an object library and used it successfully for some time. Now I've gone to a new job, I suspect that I'm using a subtly different version of Forms 6i (6.0.8.16.1), but I'm finding a strange behaviour when I try to add the object group to a form.
Dragging the object group over, I get the 'Do you want to copy or subclass the object?' message. If I select 'Copy', everything gets copied across fine - the datablocks have all the items in them and the program units are fine. However, if I select 'Subclass', the items all appear in the object navigator, but are 'empty', so the data blocks contain no items and the program units are just 'begin' and 'end' statements with nothing in between.
Funnily enough, if I 'copy' the object group into a form (so everything's present), then create another copy of the object group in the current version of Form Builder and save it in a (new) object library, the behaviour is still the same.
Has anyone come across this situation before (I couldn't find anything exactly comparable on Metalink), and what workaround (if any) did you find?
regards
Andrew

Hi again
The answer to this strange behaviour became apparent when I found bug 2772326 on Metalink.
Basically, either the OLB has to be on the FORMS60_PATH, or the option in Forms Builder under Tools->Preferences->Access->Subclassing Path has to be set to 'Keep' rather than 'Remove'. Doing either of these things solves the problem.

Breaking Subclass/Removing Object Group/Without loss of code for child form

Hi all..
This is regarding Forms 10g (breaking inheritance)
I have a base form as well as client form.
The child form is having some properties as common to the base form. so child form is having sub class(inheritance) from the base class with the help of Object Group. This is the exiting setup
Now, client wants the same information as child form with out link with base form.
i.e., they want to remove the Object Group with out distrubing the child form.
Finally, they want the child form as independant from base form. i.e., child form should not have inheritance from the base form and at the same time they don't want to loss of any code to the child form.
There are 1000's of forms like that are need to re-work.
Is there any tool/script available to do this process of work automatically.
Please provide the necessary deatils and help me regarding this.
Regards
Madhava

You CAN add new items to the subclassed block or change triggers code or even add new triggers. Form Builder won't let you create items in-between existing subclassed items or triggers. So if you need to create a new item, create at the end of subclassed item or trigger...
You can not DELETE items of subclassed block or the block itself if it is subclassed. But you can remove the subclassed object from your child module --- by removing class info from the object group in child module --- but it will also remove all the subclassed child objects.
If you delete or change anything in master object, it will directly affect the subclassed object and you can see the change immediatly in the child modules.
When you drag the master object to child, it asks you if you need to subclass or copy, selecting copy will create a separate copy which you can play with in the child module.
And below is brief help on the matter:
If you don't want all the objects in the subclassed object group, then you might consider either subclassing the desired objects individually, or creating an object group which contains only the desired objects.

how to solve a problem Thank you

Looking at both of your posts on this topic, this one and Found Error FRM-13008 Cannot find JaveBean with name oracle.forms.webutil.o I really believe that your WebUtil configuration is not complete. I ran into this same issue when I was configuring WebUtil for the first time. I attempted to take a few short-cuts because I didn't think they mattered or I thought they were already complete. After spending about 2 hours and still not getting anywhere I decided to start over and intentionally complete each step of in the Configuration section of the manual - even if I had already completed the task. Fifteen minutes later, I had WebUtil configured and working. I kicked myself for not doing that the first time! :8} You might want to consider doing the same.
Hope this helps,

Is it possible to nest object groups in froms?

Title says it all, but to explain further - I'd like to create some object groups and the objects I'd like to include within these groups are themselves objects groups.
Is that possible?

No - But you could subclass an object group and then add extra children to it.

Object Group Vs Object Libraries

Hi ,
I have not used Object Groups and Object Libraries extensively....and am trying to understand them
Having read the form builder help ,I am still not clear with the following.
My questions are as follows
1)When should I be giving preference to Object Group over OBL?
2)Why will i use an Object Group ,when an object group's object is just a pointer to the
object in the form module?
Grouping of similar objects for one single form module only,does'nt provide me much benefits?
3)How will I reference an Object group's object and not a form's object which I have
moved into the object group and vice versa?
4)OBL module has a data block(say emp) as one of its many object,
how can I use this data block in my new forms module(will I be copying this data block
object from the attached OBL to the data block node of the form module in OBJECT navigator?).
will i have to create a Layout manually if I use the data block of OBL or will forms
builder automatically create a layout for this OBL data block.?
5)What are the types of objects which CANNOT be included in OBL and Object groups?
I am aware that I can't include an item of a data block if i don't include the data block itself.

1)When should I be giving preference to Object Group over OBL?Depends on the requirement. The objects in the Object group are limited to the current form module. However, Object libraries can be used across the forms. Of course, you can subclass this object group in other modules.
>
2)Why will i use an Object Group ,when an object group's object is just a pointer to the
object in the form module?Its like a template. You define set of properties (say width, height and font for a text item), and then subclass the object to all the object you create in your form. So, they all will look similar. Also, once after creating the object group, you can add the object group to the object library. This can be very useful.
Grouping of similar objects for one single form module only,does'nt provide me much benefits?
So, here we use Object Library
3)How will I reference an Object group's object and not a form's object which I have

You cannot reference the individual objects in the object groups.
4)OBL module has a data block(say emp) as one of its many object,
how can I use this data block in my new forms module(will I be copying this data block
object from the attached OBL to the data block node of the form module in OBJECT navigator?).
will i have to create a Layout manually if I use the data block of OBL or will forms
builder automatically create a layout for this OBL data block.?You can add all the Blocks, canvaces, etc to the Object grou, add the object group to the object library. Then, if you just copy/subclass the object group from the Object library, all the blocks, items, canvaces would be created automatically in the target form.
>
5)What are the types of objects which CANNOT be included in OBL and Object groups?
I am aware that I can't include an item of a data block if i don't include the data block itself.
Only the Parent objects can be included in the Object Group (Child objects cannot). However, in the Object Library, you can add the parent as well as child objects. Here, for ex, parent is a data block and child are the items inside the data block

Forms10g Migration : Sub-Clasising Object Groups again.

While performing the forms10g migration , is it necessary to Subclass the object groups from the referenced forms in the referencing forms again. If so , what for is this necessary.
Please advise.

U dont need to subclass again. However make sure that the form from which u have subclassed is upgraded first.

SOLVED: Oracle Forms Object Groups

Hi,
I have an object group on one main form. this object group has dozens of object group children. I've copied and subclassed the object group to my dependent forms.
Now i add a object (a parameter for instance) to the main form object group... but the dependent forms object group does not add the new object and i have to subclass it manually... what's wrong?
solved sorry!

Subclass the WebUtil Object

Hi. I'm attempting to Subclass the WebUtil Object. I've attached the library to my application and I've opened the WebUtil Object Library. But how do I do this 'subclassing' to my form?
At this point I'm assuming I need an entry under the Object Group node of my form. How do I do this?
Thanks in advance.

After you've opened the object library in forms builder, double-click on it and then drag and drop the 2 webutil objects into your form. The object group goes into your object groups node, and the parameter goes into into the parameters node.
Then you need to reorder canvases and blocks so that the webutil components do not appear first when you run the form

Subclass / Object Group / Object Library error?

Forms [32 Bit] Version 10.1.2.0.2 (Production)
I am experiencing a strange problem with classes, object groups and object libraries - I have tried all sorts of combinations, but I always get the same problem.
1. Create a form
2. Creat a property class - PC1 and add a when-button-pressed trigger that does 'null'
3. Create another property class PC2 that subclasses PC1 - note that the trigger is inherited correctly and the Triger Text shows the inheritance arrow in the property sheet.
4. Create an object group in the form - OBJ1 - and add these two classes.
5. Create a new obejct library and copy the OBJ1 object group.
It is at this point that things go wrong! If you now look back at the PC2 class - the inheritance chain of the trigger code has now been broken?
Well - it ALWAYS is my system - I have tried all sorts of combinations - including changing paths, forms_path, registry etc. etc. but I am coming to the conclusion that it is a bug?
Can anyone confirm that they experience the same problem?
Regards,
Bren

Thanks Gerd!
I have tried on 10g on several machines (some identical) and some with different paths (FORMS_PATH etc.) - but I always get the inherited trigger code disassociated.
Also - and slightly strange, before I copy the object group, the properites of the trigger are perfect and the trigger code shows the inherited arrow. Directly after copying the object group, the trigger code property sheet has the un-inherited red cross, but, if I close the Form, I am not prompted to save the changes? So it's like Forms is making the change, but not internally marking the form as being changed.
Let me know how you get on with 10g - and thanks for your input!

Bren

Using Object Group.

I am using the forms 6i. And i have a problem with attach Object Group.
After attach, the form do not execute.
I have a question: What the values the Object Group utility on the registry?
Or if another sugestion...
Thanks, so much.
Martônio.

1. Did you copy the object group to the new module or subclassed it?
R- Subclass.
2. Did you compile your form module after doing copy/subclass of the object group?
R- Yes.
3. Did you get any compilation error/warning?
R-No. Because the form close before display.
4. Is the base object group is from a form or a object library?
R-Object Library.
5. Is the base form / object library in which the object group exists is there in the FORMS60_PATH?
R-Yes.
Thanks. So much....

ORA-23326: object group "PUBLIC","REPG" is quiesced

I am using Oracle 9i Enterprise Manager.
I have two servers with databases isb.city and rwp.rawat. I completed the whole process of Multimaster Replication. I am working on the SCOTT schema as test. Right now I am working on LAN.
Two servers are connected with each other. I am facing two problems:
1) When I try following command, it shows no rows on both servers:
SQL>SELECT DBLINK FROM DBA_REPSITES WHERE GNAME = 'repg';
no rows selected
2) When I try to insert data in the tables, it doesn't allow it and give following:
ORA-23326: object group "PUBLIC","REPG" is quiesced
I already made changes in init.ora and changed spfile file as well accordingly.
What is wrong with my setup?

Try this:
1. SELECT DBLINK FROM DBA_REPSITES WHERE GNAME = 'REPG';
2. You should change init.ora or spfile (database is using one of them):
show parameter pfile will show you if you are using spfile or not
execute RESUME_MASTER_ACTIVITY to unquisce replication group
