How to set first Item in combobox

Hi all,
I am struggling to find out how to set the first item of the
combobox as say "Select" because the fields i display in the
combobox
are optional for the user to select.
I have in the dataprovider of combobox set to an
arraycollection populated by a call to fill method.
But these items should be displayed below "Select".
Can anyone help me on this.
Thanks,
Lakshmi

Hi
Try
yourcomboxox.prompt = "Select";
yourcombobox.selectedIndex = -1;

How to set an item when I redirect using OWA_UTIL.redirect_url

I am using OWA_UTIL.redirect_url to redirect users.
but I am lost in how do I set an item doing this. I have an item called :P101_MSG and I want to set it to 1.
I added &:P101_MSG=1 this: OWA_UTIL.redirect_url ('f?p=&APP_ID.:101:&SESSION.*&:P101_MSG=1* ');
but that was wrong.
Can someone tell me the syntax to set P101_MSG=1 when I redirect.
Howard

Hi
I'm not quite sure of what you're doing or where you are but this isn't how you set APEX items in the URL.
See this example
f?p=:&APP_ID.:&APP_PAGE_ID.:&APP_SESSION.::::P1_ITEM1,P1_ITEM2:A,BThis sets item1 = A and item 2 = B.
Is this what you mean (make sue you get the number of colons correct...

How to set the item property to restrict the user to not to copy from above

Hi Guru's,
I have a requirement like, There were two items on the form name email Id, Confirm email Id.
I have to ristrict the user to not to copy from email Id item.. make him/her to enter the value into confirm email id item field manually.
How to set the item property to restrict the user to not to copy from above item and paste it in this item.
Please help.
Thanks!!

Just an opinion here, but that is about the dumbest requirement I have ever seen.
I am always annoyed by web sites that ask me to enter my email twice. I ALWAYS copy the email address from the original entry and paste it into the second one.
People enter their email addresses so often, it takes a real klutz to not get it right. And what makes you think that if they enter it twice, that they won't enter it wrong both times anyway???

How to get first item of hashMap w/out knowing the key

Hi
can someone tell me if there is a way to get first item from a hashMap when you dont know what the key is. as the get method expects a defined 'key'
reason I am asking this:
I am using struts 2 UI <s:radio> tag. this tag takes a hashmap and creates radio maps. it has a 'value' attribute and if something is passed to this attribute then that radio button is checked by default. the list that contains radio buttons is created dynamically so i dont know what is actually in the hashMap key's. but i do know that key's are string.
so just wondering if there is a way to get first item from a hashmap without knowing the key...

thanks for the quick reply.
posted in java forums because thought it was a java API/workaround question. gave a little history because i didnt want people to start questioning my use of HashMap for this purpose..
anywhose..i've found a workaround.
If someone has a similar problem:
as the hashmap is being populated dynamically....set a String member of class to contain the first key thats being put in the hashmap. then have struts tag pick up that value.
also, through your post and reading hashMap api...its usefull to know that hasMaps do not gurantee the order of elements in it. So now I am using a TreeMap.
Thanks

HOW TO SET A ITEM DEFAULT VALUE to today

I have a item using select list and I like to set this item default value as
today's date , such as "select to_char(sysdate,'YYYY-MM-DD') from dual"
HTMLDB failed recongnize the default value, or throw error Error ERR-9132 Error in PLSQL expression for item default code, ...". I have tried each of 3 avaialable Default Value Types
Per http://forums.oracle.com/forums/thread.jspa?messageID=443287, it is used to be doable, but the default value type (sql) is no longer avaialble in HTMLDB 2.0
I would appreaciate it very much if anyone has successfully done this before, either set to today or current month

Ching - Did you try a PL/SQL Expression using to_char(sysdate,'YYYY-MM-DD')?
There have been no changes to the item default types available in HTML DB. The thread you referenced is for Oracle Portal, a separate and unrelated product.

How to set selected item of SelectOneMenu

HI,
I want to manually set the selected item of SelectOneMenu, can anyone tell me how can I do?
Below is my code:
<h:selectOneMenu binding="#{Monitor.dropdown1}" id="dropdown1" onchange="submit();" valueChangeListener="#{Monitor.pageItemsValueChange}">
<f:selectItems binding="#{Monitor.dropdown1SelectItems}" id="dropdown1SelectItems" value="#{Monitor.pageItems}"/>
</h:selectOneMenu>I tried to use dropdown1.setValue to set it, but I wonder which class type I can use.

Initialize the value to the value you want to select:
<h:selectOneMenu id="model" value="#{SearchVehicle.modelField}">
<f:selectItems value="#{SearchVehicle.models}"></f:selectItems>
</h:selectOneMenu>public class SearchVehicle{
private String modelField = "XYZ";
}

GI:How to set Indicator:Item Not Relevant for Goods Movements LIPS-NOWAB

Hi,
does anybody know what i have to do to get the Indicator: Item Not Relevant for Goods Movements set for a good issue delivey position? (Table LIPS field NOWAB)
thanks in advance
Steffen

Hi,
the thing is the following (maybe it doesn't work at all, i don't know) :
a) i have a "Non-stock" material (e.g.material type NLAG)
b)this material should be picked, so it should be relevant for the delivery (e.g.item category TAX)
c) for a special reason the "Total goods movement status" in the outbound delivery header shouldn't be "Not relevant", therefore i assigned the item category TAX to a shedule line category that has a movement type (e.g. CN)
d)but the bad thing is, that the customer has set the indicators "quantity updating" and "value updating" for the material type NLAG, and so the goods issue posting gets some errors. eg.g missing storage location etc.)
During debugging i found a coding that checks the sign NOWAB of lips, the documentation says:
"You can use this indicator to control whether the item is relevant for goods movement when the delivery is still being created.
When this indicator is set, goods movement is not posted for this item - regardless of the movement type assigned to it."
So i head the idea it might be possible to set this indication (Lips-nowab) somewhere in the sales order or somewhere else but maybe this conflicts with point c) above .
Maybe shomeone knows what to do or has a better idea.
Best regards
Steffen

How to set Lov item property (Action type,event,parameter etc) in PR when page load

Hi gurus
I am new to OAF, First I need to explain my scenerio.
I need to make some field mandatory or non mandatory based on one LOV item (Pick list or message choice list).
for this i extended the controler and apply the changes, but in this case what heppen, It will effect only when i open the list (pop list) and click on more (Available in poplist) and it will open a new form and i select value from that form. But when I open the poplist and select the value from the same list rather going to more option (it does not open new form), then there are no effect. I though the issue with refreshing when selecting value from the same list.
To resolving this issue what i did
1. go to page == > the same LOV
2. Change the Client Action properties (
     Action type = fireAction
     event          = xxevent
    submit = true.
After doing this when i run the page from my OAF enviroement , every thing is OK. Then I transfer the Controler to Server machine and change the controller and run the same page from the server, it has the same refreshing issue, Then I thought because I did not transfer LOV such properties so this is hepening,
Now I want to initilize such properties in Page load or what I need to do, Please advise me.
Regards,
Haq

Edward,
Thank you for the suggestion! It directly lead to my solution wherein I used CASE statements for the column in my Region SELECT such as the following:
WHEN (:P2_GRADING_METHOD = 'CR/NC' OR scs.scs_pass_audit = 'P') AND GET_GRADE_B93 (sac.stc_final_grade, sac.stc_verified_grade) IS NULL THEN htmldb_item.select_list_from_lov (5, 'Enter Grade', 'GRADE_LOV_CRNC','onBlur="return validate_grade(this,''FW_DATE_'||ROWNUM||''')"','NO',NULL,NULL,'GRADE_'||ROWNUM)
When the column is NULL, the Select List (LOV) contains the entry 'Enter Grade' and that is the value displayed on page load. I bypass the value 'Enter Grade' during Submit Processing where database updating occurs.
I did not find the need to enter values for p_null_value and p_null_text since I don't believe that it would cause the 'Enter Grade' value to display on page load for null value columns but rather would enable the user to select 'Enter Grade' from the list and have a specified return value stored in htmldb_item array.
Again, thank you for the help!

How to set static item in PL/SQL

I know this may sound like a stupid quesiton but here's the issue.
I need a PL/SQL function that will set a application item, or page item etc. The items that need to be set are static items. Ex: P1_FIRST_NAME
I know if I use a PL/SQL function withing HTMLDB I can use the :P1_FIRST_NAME := 'Martin';... Problem is that you can not use that syntax if you store the function in Oracle itself.
So I need to know the syntax to set items.
Thanks.
M.

HTMLDB will also recognize variables using the format &VARIABLE_NAME. (with the period at the end). Have you tried this variable naming convention? Oracle may store it as it looks like a runtime variable.
I don't know if it will work for your scenario or not...

How to set first column as date (dd/mm/yyyy) in the specific format in excel

hi need help wat i did need help is tht i need wen ever i send view a excel data the first column set to date but some times wen i view in different type of pc the date format change to mm/dd/yyyy. is thr any way i can set the format?

If you just need to reformat a correct date to show up as dd/mm/yyyy, just use the "Format Cells" command and set a custom format string to exactly that. If, on the other hand, you are finding that Excel just doesn't get that the first value is a DAY, not a month, such as trying to graph a temperature data logger that records data in dd/mm/yyyy:
Reformat the strings as dd/mm/yyyy, using the first method. This will make them LOOK correct, even though the actual date VALUES are still day-month inverted. Now save the table as a .CSV file. This will save the dates as plain text in the correct order, which you can then re-import and have Excel now read the correct date value.

How to set first day of the week?

I'm trying to set up my iPad calendar so that my week view starts on Monday. My calendar on my desktop & MoblieMe starts the week on Monday which is what I want but my iPad starts on Sunday (even though it has been synced with my desktop & MoblieMe too). Please help! Thanks!

Actually, I tried both UK and Australia, and Sunday was still the first day of the week.
HOWEVER!!!
Woohoo!! American Samoa works, and doesn't seem to change any other formats (although admittedly I have not made an exhaustive search - just checked the International Example thing recommended by Matthias suggested.
Matthias, thanks very much by the way!!
