• Select the list with doSubmit ('SAVE')

  Dear members,
  
  Please do not kill me for that matter...
  
  I use APEX 2.1.0.00.39 delivered with XE. What I need is a list of selection within a form region indicating the content of a source LOV which is a column of data. If the select list is replaced by another value, it should initiate a doSubmit ('SAVE').
  
  I tried the list with submit - did not work. I tried to change the STI to a selection list and:

  HTML Form Element Attributes: javascript:doSubmit('SAVE');

  But both times the result I have the same thing: when I change the select list of another element, the form is committed, but after reviewing it, the original of the select list item is selected again...
  
  What I am doing wrong?
  
  Best regards
  Johann

  Hi Johann,.

  The parameter must be defined:

  onchange="javascript:doSubmit('SAVE');"
  

  What are the parameters of complete Source, you have for the item? You use any calculation a process on the question?

• Field in the list with 2 columns

  I am creating listfield with two columns as follows [2 |]  Cokes].

  There is an example on how to do this?

  There is an article on the basis of knowledge to developers to add checkbox to a field, but I don't see anything on the creation of several columns.

  Maybe I can get away with adding a field of text instead of a checkbox or have two fields next to the list and sync.

  any suggestions?

  ListField on nature has a great column.

  You can override drawListRow() to ListFieldCallback to divide each row number of columns.

  In this case, you will need to control the width of each column using the class font getAdvance() method that returns the width of the displayed string. And if you combine graphics and text in columns, you will need to also use getWidth() instance method of the Bitmap class to calculate the width of each column.

• B2B generate the file with the file extension will start

  Hi guru B2B.

  We have a problem with the name of the output file. We have customized the java class to change the file name out based on operational needs. It works well, but recently, we see the file with the extension name from "start" are generated with size '0 '. The right files always generated with the appropriate content.

  Can someone tell us what is causing this problem?

  Thank you in advance,

  NAFTA Li

  Hi Alena

  I assume you are using a B2B channel tuned to retrieve messages in a folder. Please check if this channel to listen is to have the parameter enable selected marker.

  Disabling the marker Enable should avoid generating the file start in the folder.

  Thank you

• Select the list with the list of dynamic values with more than 4000 tank of query

  Hello
  
  I have no application where users can store SQL queries in a CLOB column. This query is then used to populate the list, select a dynamic element through LOV. Following the code returns the query for dynamic LOV used to populate the select list. It works fine except when the length of the lv_sqlStatement becomes more than 4000 characters. Then application crashes with "ORA-06502: PL/SQL: digital or value error: character string buffer too small" when Select the list item rendering.
  
  Any ideas how to get around this problem? Any help is appreciated. Do not say to them to write shorter than 4000 queries because I can't (it's operational requirements).
  
  DECLARE
  lv_sqlStatement end_user_set.sql_statement%type;
  BEGIN
  lv_sqlStatement: =: P2_SQL_STATEMENT;
  return ' select the label, value of (' | lv_sql_statement | t ')
  To_char (t.value) if not in (select value from end_user_set_member eusm)
  where eusm. EUSRSET_ID = ' | : P2_EUSRSET_ID | ')';
  END;

  I just blogged about this problem and posted a solution. See this announcement:

• Fill the list with Instances

  Hi all
  
  Is it possible to fill the results in a drop-down list with the name of the entity instances.
  
  for example, I instantiated instances 4 x by the name of the child as part of the entity of children.
  

  HARRY
  BARRY
  SALLY
  LARRY

  Then on a separate screen, I want a drop-down list to be filled with the name of the child.
  
  for example
  Maybe, I have a question:
  

  what is your favourite child (which is a drop down showing 4 instance names (HARRY,BARRY,SALLY,LARRY)

  I'm on v10.1
  
  
  See you soon

  Hello

  There is a way to make this out-of-the-box, but all depends on your data model.

  I assume here that you have 2 entities, the person and the child. The child has an attribute called 'name of the child. "

  Creates a one-to-one between the person and the child relationship, that he calls "the child preferred person '...

  Then, create an individual question screen. Add a control to the "relationship of entry" to the screen in question. For the 'legend', write something like "Please choose your favorite child." For the "attribute" display, choose the name of the child.

  This will display the question exactly as you want - it will ask the user to select from a list of all children.
  Of course, if the person can have many favorite children, create a relationship one - several. However, this will display the names of the children as the boxes, because the user is now allowed to select more than one.

  If the relationship is just together, you can then use this relationship to access the name of the favourite on the level of the individual child (using InstanceValueIf), or you can run the rules that apply only to the favorite child.

  It's just a suggestion that Ive just tested in 10.3, I did 10.1 at hand at the moment but don't remember which is new to the brand (others, please correct me if I'm wrong). Give it a go, see if it works and get back to me, if it's not. If this does not work on 10.1 you should certainly consider the upgrade to 10.3 for a host of other reasons too. Otherwise, it is achievable with a custom control.

  See you soon,.

• The list with many images

  Hello!

  I have a list with a lot of images in the itemRenderer, over 500.

  I use virtualization on this list.

  When people scroll quickly down, it can take a bit to load images.

  Issues related to the:

  1. in what order the list control to load images? Up and down the entire list or Topp down only the visible part?

  2. is there anyway I can give priority to a certain image to load first on others? The images have the source property set to a relative path on the server.

  3. is there anything I can do to speed up the process of loading in general?

  Thank you!

  The list does not load images, because of your item converter.  I suppose you load these images by substituting the data setter method in the rendering engine.

  When the list of the first loads it creates just enough converters to show what is in view (due to virtualization), let the top 10 items.  This means that the first 10 images will be loaded, but no other images will be loaded unless you scroll the list to expose new items.  If you want to have some images available before others so you can have your application load them if its not busy and in this way, they could be available before the user scrolls.

  Even if you were to load all images before creating the list you might seem still some flickering when scrolling because what are they are recharged in as user autour scrolls.  To remedy this, you might want to consider caching the images as they are loaded, there is an example here: http://flexponential.com/2010/01/10/caching-images-loaded-from-a-spark-item-renderer/

• The list with the variable row height

  Hi, please look at the example below

  What I do is:

  -J' I create an item in list with variableRowHeight set to true.

  -The dataProvider contains 2 numbers: 2 and 3

  -In the itemRenderer, this causes in progress of creation, respectively 2 and 3 buttons

  -As you can see, the height of the list is badly calculated, a scroll bar appears.

  -When you switch 2 and 3 (so that the table becomes 3 and 2), the list is too large.

  -I could make a custom list class and override the method of measurement, but I can't understand what to measure. I should be able to walk through the itemRenderers and measure their height.

  Any ideas?

  THX,

  Dany

  Sorry, it's a method on a list called measureHeightOfItems.  The results,

  Add viewMetrics.top and down and you should have the exact size of the

• generate the List component: make all child elements on createComplete?

  Hello

  It is my understanding that a list created only children who are visible and children who lie immediately next to the display window. When scrolling, the other children in the list are created when they are ready to be displayed in the display window. I understand that it is an internal mechanism to free up memory and speed up the rendering of provision process.

  My question is, it is possible to set a property or to create a method to add all children is made in the list at present, it is created, rather than limiting children to only close the display window? Thank you b

• no selection in the list with custom itemRenderer

  Once an itemRenderer custom, consisting of a canvas with image and label, submit to a list control that list loses the ability to choose. the selectable attribute is set to true. There are no managers in the renderer that can eat the event.
  
  How can I provide the itemRenderer custom without losing the functionality of the list?

  Theoretically, you should avoid using containers as element converters because they are 'heavy' with the functionality you don't need.

  Best practice is to extend or to copy and modify ListItemRenderer.as. The source is in the file framework somewhere.

  This is not trivial, but it's not rocket science either. The Adobe code is quite clear and well commented.

  In addition, google: Alex Harui element converter, for a few examples by a master of Adobe.

• Select the list with propose pulling the values of %

  Hi all
  
  I have a tabular presentation of data app and from views of the choices selected in the 'list of selection with submit' the post, it works very well for the chosen values, when I choose '%' I want to display all existing records in the form of tables, but instead he said: "no data found". How to solve this? Kindly help and advice.
  
  ex:
  
  Query tabular-
  
  Select a, b
  table
  When a type: POINT
  
  Agenda:
  
  Type: select the list to submit
  Named LOV:
  Select a d, a r
  from table_recherche by 1
  
  Receive your answer.
  
  Thank you and best regards,
  Senana

  Hello

  You have to check what is the value returned by the selection list when you select '%' in the select...
  There is a null value to display field where you can enter '%' and the return NULL value you enter 0

  then change your query in a table
  Select a, b from table when one like: POINT GOLD: ITEM = 0

• Select the list with a shipment does not save to the database

  OK, I have a form with several fields (text, radiobox, selection list, display text). I have one of these lists of selection fill a display in the text field. When I chose a selection of the selection list, she filled the screen in the text field with the correct information but erased all the other information that was the inscription in the other fields. I searched the forum and found that the selection list should be a selection with mailing list and the branch page on itself, which works, but now these 2 fields information is not saved in the database. All other fields are saved, but not both. Anyone know what im missing? Thank you
  
  Deanna

  Hi Deanna,
  First the display as a text cannot insert data into the database. It can only display data from database. I guess you do not want the user to enter these areas, and that's why you use display as text field.

  There is a good way to resolve this situation. Say, you have 3 select list P1_ITEM1, P1_ITEM2, P1_ITEM3 in your page. For the change of P1_ITEM1 the screen Select the list and the LOV type in your query, assuming you want the value to be retrieved from a table. Therefore, type-

  Select emp_id, ename from emp;

  type the default value and null -1 and display null YESvalue. Make sure that under the type of source, you have the selected with the correct name database column.
  for P1_ITEM2 to the section LOV retype your query - i.e.

  Select mng_id, executive pay where emp_id = NV('P1_ITEM1') or NV ('P1_ITEM1') = 1

  Basically, this statement updating the data in the list select second after the first selection. type the default value and null -1 and display null YESvalue. Make sure that under the type of source, you have the selected with the correct name database column.

  Do the same for the third. It should work fine.

  I hope this helps.

  Kind regards

  Don't know exactly what you are looking for, but if you want to just set the number from 1 to 999999999, query below would:

• Generate the AO with digital triggering

  Hello, I have a problem, generate a continuous waveform (custom channels multlisample) when a TTL - as 5V 0V trigger is applied to PFI0. The problem is that synchronization source is running continuously, when the digital voltage line is connected I don't have to keep a single waveform sent, as opposed to a regeneration of the same waveform.

  I have worked with some conditional loops, but nothing works, is there a solution that can provide two triggers (one for a pulse train) and then for the digital falling edge (on 0V) which can allow the regeneration of the writing of the AO?

  Thank you

  DB.

  Hey DB,.

  I recommend using a pause trigger.  This will allow you to exit when a certain level of TTL is high (or low) and not when the opposite is true.  Here is an example that illustrates the break trigger using property DAQmx nodes.

  You need to change the time by continuous for this example sample clock, but also to change the data to be written to fit your application.

  You can leave the writing of the initial value in the analog output channel if you wish, or you can delete the original entry, start and stop functions DAQmx.  Either will work.

  Best,
