JComboBox doesn't show all Rows in the View Object

Hi,
I've got a JComboBox which shows only 25 rows of the VO and I'm sure there are at least 50 or more rows.
I'm also sure this is not JComboBox.maximuRowCount's fault, which just in case i've set to Integer.MAX_VALUE.
Why is this happening? How could i change it?
Thanks in advance. Pablo.

set the RangeSize attribute of the iterator that is populating the
list values to minus one (–1). This will ensure that all of the possible list
items will appear in the list. Failure to do this will restrict your lists to a
maximum of 25 entries, the default value of the RangeSize property.

How to Insert the row in the View object

I want to insert the row in the view object by instantiating Impl.java file
Could someone please let me know how to insert the blank row
Thanks

Inserting onto a view object should be done the following way:
//vo is your view object
Row aRow = vo.createRow();
//Set your attributes
aRow.setAttribute("AttributeName", objectValue);
//insert
vo.insertRow(aRow);
That should work for you if you are programming the input. If you are using java components bound to columns in a view object then the input should be done automatically for you when you commit.

ICal doesn't show all text for the activity

When I updated to iCal version 8.0 i noticed that when I am in week-view, iCal doesn't show all the text for an activity, although there is plenty of room. For example I have a lecture from 9 am - 4 pm and in the activity I put down all the things I have to do, but it only shows the first line for my activity. I need to drag the box or double click on it to see all the text. Can I change this?

Gabriella,
Sometimes making the Calendar window bigger, or using full screen allows additional text to be displayed.
View>"Make Text Smaller" is also an option for those with Eagle Eyes.

Is it possible to show all content in the view?

When using the viewer window content that falls outside of the bounds of the composition is cropped. Is there a way to show all content similar to how flash works? This would arranging things a whole lot easier!

Haha! I was about to say how this is annoying - i'm trying to make a big structure and then zoom around it and then I realised....build the structure and then make the camera move, not the object! It's obvious really! Ugh...you've got to love fridays.
Thanks anyway!

MF60 Pull List doesn't show all components in the BOM

I just switched to REM and use MF60 for replenishment. I have some products that use 2-3 FGS in the BOM. While MF60 lists out requirements for components, it does not list any requirements for FGs in the BOM. For eg product Y contains A (FG) and B(comp). However when I run MF60, it shows me to pull only B even though A is missing. I would appreciate if someone can help.

Dear KB,
What's the specific reason for treating A as a finished product and why to include A under the BOM of Y(Finished Product)?
Check if there is sufficient stock for A, already in the required production storage location,in this case the system does not
show the material A in the missing parts for staging.
Check and revert back.

JDeveloper doesn't show all files in the directory

Hello,
I think some basic functionalities are missing in JDeveloper, one of these basic functionalities is the importing of files. You can't import existing business components in your project, so you have to put them in a directory physically.
I did it like that and now I'm facing this problem that some file's aren't being shown in the application navigator while I select system navigator, I see that they are in the correct path. I really don't understand why my project doesn't include the files in the application navigator...
Can anyone tell me what's wrong or what to look for?
Thanks.

NumChildren doesn't show all children in the movieclip

Hi, I have 2 movie clips inside another movieclip, when I trace numChildren on the parent movieclip it only shows 1. Anyone know why?

Without seeing what you have the only guess anyone might have is that you are mistaken in your thinking and there is one child in the movieclip. Is the second child a child of the other child?

Programatically inserting rows of a view object trouble

Hi,
I'm using JDev 10.1.3.3. I'm trying to use the application module specific to my app to create rows in a viewobject. User is on page "view", goes to page "new" and fills out a form which upon submit sends the data to an Application Module method I've exposed to the client. What doesn't happen, is when I add the row of the view object programatically in my view object, it doesn't display on the "view" page until a commit is done (when navigating back from the "new" page".
Here is some sample code of the insert into a composite (not composition) viewobject. When I insert in the new page, it returns to the view page... and the row doesn't show up until commit happens:
//in my application module
public void doiIt2(String name, String badge, String item){
UserItemViewObjRowImpl row = null;
row = (UserItemViewObjRowImpl)getUserItemViewObj1().createRow();
row.setBadge(badge);
row.setBadge1(badge);
row.setItem(item);
row.setName(name);
row.setNewRowState(Row.STATUS_NEW);
getUserItemViewObj1().insertRow(row);
getUserItemViewObj1().executeQuery();
Does anybody know how to get this row to pop in, like using a "creation form" to a table in a view page? What am i doing wrong??? Do I need to do something special in my pagedef of the "view" page?
Thanks,
Dan

Chris,
Thank you for looking at my problem. The row is not inserted into the table (on the view page) with the code I shared. The criteria for the table's VO is simply a select all, with no where clause, so I don't think I'm excluding it... Upon hitting a commit button, the new row does pop in to the table witch is further evidence that the criteria for the VO isn't excluding the new row.
I have tried insertRowAtIndex(), even before I posted this with no luck.
BTW, if I add to the bottom of the code I shared, getDBTransaction().commit; or getDBTransaction().postChanges(), the row does pop into the table when the "view" page is navigated to.
Am I doing something wrong with my construction of my ViewObject? It is a composition (I got that wrong in my initial post) between two entities. The Item entity is updateable, and not a reference using an association between the two entities on the Badge attribute.
I am trying to have new composite VO rows always show up as the first item in a table. I've read that the Row.STATUS_NEW will always do this... so I'm trying to avoid posting/committing the new row. I'm also not above inserting at a particular location, but some of the pages I hope to use this pattern with re-execute the VO every time the page is rendered, instead of just rebinding the Iterator with the VO rowsets. I'm being led to believe that if a Row is posted or committed, re-executing the query will resort all rows based on 'order by', etc.
Also, I have setup a similar yet even more complicated example using three entities. I was able to make this work as expected. The difference is that I was using an ADF Creation Form. ( I did have some work in the model to make all the keys line up though.... posting order... etc.).
I have gotten similar things like this to work with single entities VOs. I'm just having trouble when I do composite VOs. That is supported, isn't it?

Package Body in the tree doesn't show all procedures

I am using Sql Developer 1.0.0.14.67 on Win XP Professional,
DB servers Oracle 9i on both Linux Red HAt and Win XP Professional
I have troubles with one of packages - in the tree under Package Body SQL Developer doesn't show all procedures of this package body.
On the right panel all package body source is shown, but in the tree under Package Body it shows names of only procedures up to certain line in the source code - up to line where first Private (not included in Package Spec) procedure code starts.
BUT, there are more Public procedures in package body below this Private procedure - and all of procedures below first private are not included in the tree under Package Body

I find this quite annoying. I cannot use the navigation panel on the left to find the location of all functions and procedures in the package body. The 'missing' procedures are listed under the package spec, and double clicking on them takes me to the spec and not the body.
I'm running v1.2.1.32.13. Is this a know issue and is there a fix planned?

Report Region show all rows?

Hi,
I have a report region in which I want to show all rows. Setting the pagination scheme to No Pagination doesn't
seem to do the trick. I have set Number of Rows and Maximum Row Count both to NULL. Nothing seems to work.
Is there some trick to get all rows to be displayed?
Thanks in advance!

Hi,
I have two report regions on different pages. On both I have set 'Number of Rows' and 'Maximum Row Count' to null. One report will return all the records in a query (~800), the other report will only return 500. I can't see any other differences in the reports that would cause this behaviour.
I didn't really want to restrict my reports to a set number of rows, is this really the only option?
Thanks,
Rochelle.

InsertRow does not show the inserted row on the view

hello:
The code below works well and shows the row on the view when added. However, when there are several existing rows and I have to scroll to next pages. an insert button on that page does not show the new Row at all. Is there a way for me to see the row even if I scroll over to the last page and try an insert?
ViewObject myVO = this.getMyView();
Row newRow = myVO.createRow();
newRow.setAttribute("Id", myId);
myO.insertRow(newRow);
Thanks

Hi,
I also have problems with code above for inserting a new row.
When I insert a new row in a table and click on column header (to change sorting), that row (and any other new row before committing) disappears from table. And if I commit that table (without missing row), the missing row reappears with next refresh.
Selection in that table (using SelectOne component with Autosubmit=true) also doesn't work with new rows (with existing rows it works fine). Selection allways sticks on first inserted row!
Something weird is happening here...
Please help.

Syncing iphone and can't seem to transfer audiobooks that i have put in a playlist. Sync menu doesn't show all playlists. Help

syncing iphone and can't seem to transfer audiobooks that i have put in a playlist. Sync menu doesn't show all playlists. Help

I have the same problem with podcast playlists. When I go to the music window in my iPhone devices section, the playlists I have created on my macbook pro in iTunes do not appear as an option to sync with the iPhone. I know some web radios streams, like the BBC, won't transfer because of compatibility issues, but the playlists of podcasts that I have created consist entirely of podcasts downloaded from the podcasts section on the iTunes Music Store. They used to show up and sync properly before I upgraded to OS 5.1.1, but now they don't.
Does anyone have a fix and am I right in surmising that the cause is a glitch in OS 5.1.1?

ATV doesn't show all photos in slideshow

My ATV3 doesn't show all my photos in slideshow. It seems to repeat the same, say 50, over and over, even though I have about 400 in the folder on my windows7 PC.
Whats the fix?
Thanks
Andy

For the avoidance of doubt are you talking about the screensaver or the slideshows.
Slideshows should show all your photos, but screensavers will not. Screensavers need to save the photos to the Apple TVs flash storage, the Apple TV doesn't have a lot of this and so limits the number of photos it uses.
