If you already have a lov to choose "judet" from, why don't you include the id-colum,n also in your lov (with width 0 it would be invisible) and set the return-item to your :elevi.id_judet. WHEN-VALIDATE-ITEM-trigger wold be the right place to do such actions.īut. what's the problem? shouldn't be updated automatically when i select the name of JUDET from a LOV ?īest regards, You shouldn't use the POST-CHANGE-trigger.
Oracle 6i form force text box to contain lov values update#
i have a POST-CHANGE trigger, which i wanna be fired everytime i select a different value from that LOV.ĮND so i wanna update ID_JUDET which the ID of judet each time i change the name for JUDET (from that LOV).īut using that trigger the problem is that the ID_JUDET field isn't updated automatically, just when i click on it, or i do something, but not everytime. I have a problem at a POST-CHANGE triggerįor example, regarding to JUDET Text item. I tried what you suggested, and set the condition like if :id is null. When I slect certain value from the list of ID (this item is not connected with database by lov), the other 2 list items can't populate values from record groups. If :blk.ID is null then go_item('BLK.ID') end if The problem is:

Use a when-new-item-instance trigger on each one of the other items that forces user to enter ID if it is null: Populate_list('PRODUCT_ID','LOVGENERAL') Īmber Use a when-validate-item trigger on ID to populate the other lists. If I choose the value from ID list, and set trigger when_list_changed, then can't populate values anymore. The problem is if I don't choose ID from the list, only set triggers for the 3 items WHEN_NEW_ITEM_INSTANCE with populate_list, only the first list which i click got the populated values, others can't. Also one LOV called LOVGENERAL does the mapping job. A table called GENERAL_TAB has the connection with these 3 items. What I want to do is, when users choose the value from ID list, the form will popluate the other 3 items with the value got from database, the condition is like: select procudt_id, typeid, brand from GENERAL_TAB WHERE typeid=:id. In this block, I have 4 items: ID (list), TYPEID (text item),PRODUCT_ID(list) AND BRAND(list). Populate values in poplist based on other item's value Hi, all,Ĭould anyone give me some hint on what I should do? SELECT '0',0 FROM DUAL excuse me for late. Try re-creating the record group wiht the new query. I have a foreign key constraint on this field in the database? Would this block an additional value from the list? no, a FK should not be a problem. I think I might know why I'm having a problem.
Oracle 6i form force text box to contain lov values code#
I replaced my code with yours (making necessary item name changes, etc) and I still don't get a 0 element in the list. I'm populating the list in several places - WHEN-NEW-FORM-INSTANCE and as part of the code on a "FIND" button What trigger do you use to populate the list? Populate_List('BLOCK.LIST_ITEM', 'RG_LIST') Message('Error loading list data.', no_acknowledge) Now I tried your query on sqlplus and it works, try this code to populate your list: I think that part is not working when a list populated with record group all the items added trhugh the property "elements in list" should be removed. How do you populate the list from record group? I'm not sure if this info helps but wanted to give as many details as I could. And I'm using the POPULATE_LIST method to populate the combo box. The field I'm trying to populate is a database item of type NUMBER. SELECT '0','0' FROM DUAL Acck! :o) Still just a list of application_id's What have I done wrong? I'm still just getting a list of application_id's helo, Then I went to the properties for my database element (combo box) and added the element 0 with value 0 SELECT TO_CHAR(APPLICATION_ID),TO_CHAR(APPLICATION_ID) FROM APPLICATION WHERE REF_NUM = :PARAMETER.P_REF_NUM

I used different values than what you suggested but shouldn't I get the same result? Null value in Combo Box - Forms Is it possible to include a null value or a "none" option in a combo box that is populated with a record group? yes,Īnd insert in your elements list (combo box)
