ADF Table export Causes flicker

• Export an ADF table with default column order

  Hello

  Jdev 11.1.1.5.0

  We have ADF Table with column drag and drop option. Also we have implemented ADF Table with excelHTMl type of export.

  Everything works as expected. Only problem is if we try to exchange a few columns by drag-and - drop option and then export the table, we receive the order of the columns with brewing. But our demand is, the user must obtain the export with the initial order table by default.

  It would be great, if you can suggest an idea to export the ADF table with default column order.

  Thanks in advance,

  MSR.

  I realized the required functionality. We can restore the default order of the columns to aid

  	Function richeTableau = this.getFetchResultsTable ();
  	Iterator rItr = rTable.getChildren () .iterator ();
  	{while (rItr.hasNext ())}
  	((RichColumn) rItr.next ()).setDisplayIndex(-1);
  	}

  Then we can call the real export help feature

• Updating of the ADF Table strangely after delete line

  Hello

  I use ADF Table with ArrayList to the model of the collection. I do not use View object

  < af:table var = value ' row' = "#{pageFlowScope.dataBean.collectionModel}"... "

  I have a SelectOnceChoice in each row of the table and bind their values to a property of the line

  < af:selectOneChoice value = "#{row.label}"... "

  I have a command link to remove each line and the delete method:

  collectionModel.remove (idx);

  The model is correctly updated, but the table of the ADF is not. Somehow, the value of the selection of the next line is set to the value of the deleted row.

  For example: If there two select with values respectively: Foo, Bar. If I remove the line with Foo, the remaining line (initially Bar) is set to Foo.

  If I refresh (F5) the page, it appears correctly. I also tried to use addPartialTarget and partialTriggers but no help.

  Can someone help me? Thanks in advance.

  Hello

  Previously I use table binding, that's why it has that name.

  BTW, I don't know what's causing the problem. It is related to the life cycle ADF. I put the immediate = "true" for the select box and it is working fine now.

• ADF table large number of records

  JDeveloper 12.1.2

  I have an engine of research as well as an array of result. In some research, it is possible that the result set is more than a million records. The problem is when the user uses the table scroll bar and quickly tries to go at the end of the result set, weblogic with error, memory, it blocks. What is the best practice to handle this in the user interface?

  I think of several ways to resolve and would like if anyone has experience with one of the following:

  1. when the user performs the search, run select count (*), and determine the number of records search will return. If say greater then 1000, warn the user to refine the search criteria. This seems to have made an extra trip to DB

  2. implementation of the pagination of the table instead of the scroll bar. Is this possible in the last ADF table?

  3. go to the front and back only to say 1,000 records and warn the user that not all records are returned, and that it would be best to refine the criteria. Similar to 1, except no extra trip to DB

  Thanks in advance for comments and maybe the solution

  Insufficient memory is caused by the underlying ViewObject that retrieves and keeps track of all the lines to the position where the user scrolls to the bottom of the table. It is behavior of the VO when the VO is configured with the access mode "Scrollable", which is the default access mode setting. For example, if the user scrolls to the No.100000 line, the VO to get and keep in mind all the lines n ° 1 to No.100000. This means that the table pagination will NOT help you!

  Fortunately, you have two simple options out-of-the-box:

  1. The 1st option is to configure the original Version of extraction does not exceed a fixed number of lines (for example 5000). You can do it in the "General" of the VO definition dialog page. Go to the 'Tuning' section, select the option "only up to line number" and enter the number chosen in the field of text next to it. In this way, what the condition is entered by the user, the VO will seek no more than the specified line number.
  2. The 2nd option is to configure the VO with "Range Paging" access mode rather than the default access mode "Scrollable". With the access mode "Range Paging" the VO not go get and keep in mind all the lines until the currently selected line, but he keeps in memory a few line ranges (for example only a few dozen lines). This way you will not be affected by an OutOfMemory error even if the user scroll down to a millionth line. The downside is that when it is configured with "Range Paging" the VO will have to rerun the query each time when he needs to pick a different range of lines. If the execution of the query is slow to the DB server, this will load the DB server and the user will experience delays when scrolling in a different range of lines.
     Take a look at the documentation for more details here: View object performance tuning (read article 9.1.5).

  If you decide to use "Range Paging", don't forget to set the appropriate size, which is not less than the usual number of visible lines in your table on the page. If you set the size of the lower range, then the original Version will have to fetch more than a range of lines, which will need more of a running query. The size of default in the definition of VO is 1, but it is not important. The important value is the size of the range that is defined in the iterator binding in the PageDef, which overrides the setting of the VO. The default value for the size of the links of the iterator range is 25.

• rowSetIterator.getRow (key) is null first time click ADF table row

  I noticed that the key is never null.  Something is still getting filled.    No idea why this glitch.  Why always 2nd time click work?

  I also checked thatRow myRow = rsiSelectedRows.getRow(key); is showing  myRow as null  for the first time. But  2nd time when I click and hit button,  myRow is not null !!  Do not know what is this glitch.

  


  Appreciate your help.

  Thank you

  Finally I was able to solve the problem.   Noticed that code clear filter in backing bean caused this problem.   I am clear the filter of bean support when the user forgets to clear the filter in the user interface and that caused the issue with table selection.  I commented on this code and table selection works perfectly well.

  You need the table setValue. Take a look at these discussions: programmatically set another link to Table read-only ADF and http://stackoverflow.com/questions/22389813/change-the-displayed-value-in-adf-table to get a few first thoughts and feel free to come back if you get stuck somewhere.

• The ADF Table data validation and highlighting

  I have an ADF table, supported by a VO. Gets the data loaded from a spreadsheet file. There are some required columns marked with the required attribute. the columns do not get highlighted when loaded data are empty. How can I get auto table validated during the loading of data and WITHOUT a commit / submit to the rear end table?

  My requirement is.

  1 load the data into the table.

  2. a way to highlight the rows or columns that have no values (how?) I tried the style inline for column as #{row.bindings.invamt == null?' background-color: Red;': ' background-color: White;'}, but no luck.

  3. validate data from db.

  User, tell us your version of jdev, please!

  If the table is editable, you can add this to the inputText of the column

  contentStyle = ' #{empty row.bindings.PhoneNumber.inputValue?» "{- color: red;':"} ".

  For the PhoneNumber column. If the table is read only the cellular connection is

• How to get the selected row in a programmatic table of the ADF (table generated from a bean)

  Hi all

  
  

  We use JDeveloper Studio Edition Version 12.1.3.0.0 and deployed on GlassFish Server Open Source Edition 3.1.2.2 (build 5) and connect to the SQLServer database.

  
  

  How to get the selected line in a programmatic (using a SortableModel custom not a display object) ADF table (generated from a bean)?

  
  

  We are trying to get the selected row in a bean of a programmatic ADF table to retrieve data based on the selected line.

  
  

  Any idea?
  

  Well, you can use selectionListener to set the selected line to a variable of bean (but this bean must be in extended view or some superiors)

  Something like this: http://www.awasthiashish.com/2015/07/get-selected-row-singlemultiple-from.html

• How to create a pagination ADF Table in JDev 11.1.2.3.0?

  Hello

  I have a requirement to create ADF Table Pagination in Jdev 11.1.2.3.0.

  11.1.1.7 Jdev, I see there is an option to create a pagination by setting "scrollpolicy = page.

  I'm not able to find such a property in Jdev 11.1.2.3.

  Y at - it another option to do this declaratively?  I want to avoid java coding for this.

  But if the coding of java is the only way, ask to suggest a better/more secure approach for this.

  Thank you and best regards,

  Tejas desrousseaux

  I'm afraid that you do not have this option for 11.1.2.3.0 out of the box, but you can make it work, please see below:

• ADF table refresh in the db table does not

  Hi people,

  I have an ADF table based on a table of db. It also has a box - a transitional attribute. When the button called, kicks historical method of a stored procedure to treat assets selected (from box). After that the ADF table should get updated based on the underlying table of the db. When the button is pressed, it calls a managed bean. Code in it is below. The moveAssets is a methodAction defined as PageDefinition links. Even though I have executequery on the iterator, it is not update / take into account changes in the db table. Could you please suggest me where I'm wrong?

  public void MoveAssetsbtnMtd (ActionEvent actionEvent) {}

  Add the code in the event here...

  BindingContext bctx = BindingContext.getCurrent ();

  Con DCBindingContainer = (DCBindingContainer) bctx.getCurrentBindingsEntry ();

  Note "moveAssets" is the Id of the link actionMethod in PageDefinition

  OperationBinding oper = con.getOperationBinding("moveAssets") (OperationBinding);

  Because the method takes a parameter, send the ToLocation to assign it with ParamsMap

  oper.getParamsMap () .put ("vToLoc", resolveExpression ("#{bindings.")) HZLocations1.attributeValue}'));

  oper.getParamsMap () .put ("Param2Name", "Param2Value");

  System.out.println ("Moving asset for:" + resolveExpression ("#{bindings.") "") HZLocations1.attributeValue}'));

  Execute a method

  Oper.Execute ();

  
  

  Look for the error after the execution of the method

  If (oper.getErrors () .size () > 0) {}

  Handle any error here

  System.out.println ("error in MoveAssetsbtnBean");

  }

  Update the table of the ADF of material movement hist table

  After you have moved the selected assets - 20150429

  DCBindingContainer links =.

  (DCBindingContainer) BindingContext.getCurrent () .getCurrentBindingsEntry ();

  DCIteratorBinding iter1 = binds.findIteratorBinding("AssetMove1Iterator");

  ITER1. ExecuteQuery();

  }

  Thank you

  It should be fair enough, yet can you check number of VO lines after the call to the stored procedure to ensure that the data is updated in ViewObject?

  and if t is not then when calling executeQuery on viewObject and then check again

• SelectionListener ADF table fault line did not

  Hi all

  I came across this well-known problem:

  SelectionListener not firing when only 1 result of searching in a table

  SelectionListener ADF table question

  Listener First Row af selection problem: table in ADF 11 g | _outwardBound

  Basically the selectionListener on the table of the ADF is not triggered for the selected standard line, or if the table has only one line, when you filter a column and the result returns only a single line or even when you turn off the filters and it shows you once again all the lines, marking the first such as selected.

  To summarize, the selectionListener is launched when the user clicks on a different line, but not from the default (even if the user clicks on it on purpose).

  I know that there are a few workarrounds, but who may not be suitable for the use of each case on these old threads.

  I think that, given that the line is selected (does'nt matter whether or not it is by default), the developers expect the listener to be pulled in all cases and that this behavior is a bug.

  My question is, given that this problem is still happening in jdev 12.1.3, if there are plans to fix this in future versions.

  Thank you.

  We cannot answer that. To get a response, you must file an SR with support.oracle.com and seek support for a date it a fix.

• ADF Table - current line does not prepare the first time.

  version 12.1.3

  I try to display data from a rest service as ADF table (select read-only, a single line). I added the edit on the last column button, so each line has its own button change (it is a requirement). By clicking on edit takes you to the next page to change the selected line in the form layout.

  The question that I am running is, when first loading of the page and display the table and if I select a line any except first and click on 'Edit', it still gives me the first row. It works as expected when I click on other lines in a subsequent attempt.

  How can I solve this problem?

  Thank you very much.

  Found the fix. I have just the property "immediate" of the button to true.
