Cant able to view details of current line

• Master / detail prevent insertion line detail if the master does not exist

  Hello
  
  I have a complex page that has several pairs of master / detail on it. I have what should be a simple problem to work around that I can't understand. On each table (master or detail), I have a button create header and a delete button in each row. I have a few questions, I can't seem to cross.
  
  1. how to turn off the details create button if there is no master of the line or one has not been selected by the user? (At the moment you can create detail without a valid master line rows)
  2. how to disable the removal of main line button, if there is (or not) details of current lines?
  
  I think I only got 2 having a transient attribute on the main line that uses groovy and the accessor to link views to count the detail rows. It seems to work, but if there is a better solution, cleaner I'm all ears. I can't seem to operate 1 little matter what I try.
  
  Thanks for any help you can provide.

  Hello

  You can use iterator estimatedRowCount to disable the button of

  disabled="#{!(bindings.mastervoIterator.estimatedRowCount ge 0)}"
  

  and use the currentRow determint property if the current row is selected as

  disabled="#{!(bindings.mastervoIterator.currentRow ne null)}"
  

  Thus, the combination will be as follows

  disabled="#{!(bindings.mastervoIterator.estimatedRowCount ge 0 and bindings.mastervoIterator.currentRow ne null)}"
  

  I hope this helps...

  Kind regards.

• [SOLVED] Current line of flow losses - use different iterators

  Hello.

  I use JDeveloper 11.1.1.7.0 and I have this problem.

  I will try to explain the best I can, because I can not download images.

  I have a flow. The first view, named mainTable.jspx, has a table with the current data and new data button.

  Each row in the table has a setCurrentRowWithKey link to Edit the selected data. With this link, the current row is selected.

  • Link to modify the action is Edit stream, which navegates to editData.jspx
  • New data button action is new stream, which navegates to the create operation, then to editData.jspx with empty fields.

  The behavior of editData.jspx 's right, so there fields empty with the new stream or filled with fields with flow of change .

  EditData.jspx I have a custom button check with action. I'm doing some checking, so that if there is an error, I have an error with FacesContext.addMessage. This button makes no delete, Commit or Rollback operation.

  Well, my question is with the following steps:

  1. Go to mainTable.jspx
  2. Click the Edit link in a row
  3. Go to editData.jspx
  4. Click on the check button
  5. One check is not ok, then an error message is displayed. Now, this happens:
     • Deletes the current selection data, and the previous line of data in the table appears in editData.jspx
     • When I click the back button to return to the table of mainTable.jspx, the initial line selected in step 2 is not indicated in the table.
     • In the database, all the data exist, even data ghosts .

  I don't know what is happening. Is there no delete, Commit or Rollback operation in the issue button.

  How can I fix? Is there something I'm not directly into traffic?

  Any help would be much appreciated.

  Thank you

  * EDIT: well, as suggested by Timo, executeQuery lost current line.

  My problem is produced because a misuse of iterators.

  In some controls of my explanation, some steps get current line from an iterator and reuse the same iterator to get another set of lines by executeQuery, so the current line has been lost and it involved an inconsistent state.

  The solution is to create another different iterator, since the same point of view, but another iterator with a different name. Thus, the main iterator maintains the current line, and other additional operationes, queries, etc. are made by different iterator.

  It will be useful. Concerning

  Well, if you are using the same iterator to access different data, it is expected that the current line changes. The secone selection changes the current line. What you can do is to use a secondary set of lines to get to the other row or save the current line before select you the ranks, to make your checks and set the line current when you're done.

  You will need to disable the "minimize" and the button "expand" button

  Implement customization of forms at the level of the FORM as a TIMES-NEWS-RECORD-INSTANCE / COMMAND (if you use a TIME - NEW - FORM - INSTANCE that does not trigger action when opening an order of the organiser):

  Type = property
  Object type = Item
  Target the object = ORDER_CONTROL. EXPAND

  I was on facebook and remove an icon by using the right-click menu, but then all my photos and pictures of profile, could no longer be seen. I was able to view them in the browser, so it's something I've done in Firefox. How can I unlock a site?

  If you select that right click menu context then you block all images from this area and not a specific image, so do not use that.

  • Check exceptions in tools > Options > content: Load Images > Exceptions (for example sphotos.ak.fbcdn.net)

  You can use the following steps to check if the images are blocked:

  • Open the web page that has the missing images in a browser tab.
  • Click the site favicon (How do I know if my connection to a Web site is secure?) on the left end of the address bar.
  • Click on the "More information" button to open the "Page Info" with the Security tab selected (also accessible via "tools > Page Info").
  • Go to the Media of the window tab "tools > Page Info.
  • Select the first link of the image and scroll down through the list with the arrow down.
  • If an image in the list is grayed out and there is a check mark in the box "block Images of..." and remove this mark to unlock the images from this area.
