How to delete empty element in popup list - oracle11g

I have a question about a suspicious behaviour in Forms Builder 10.1.2.0.2.
When I have a list object (pop up list) I can define some values in the attribute palette of the object.
So you can set a shown name and a value behind. In this little window to set the items of the popup list you get automatically a white empty item at the end of the list. When I click now on this empty item (you do so, when you want to add an item) Forms Builder automatically adds an new empty item at the end.
When I click this new empty item, Forms Builder adss another empty one ... and so on.
It´s very suspicious because, when I end this dialog with "OK", it will be saved and when I open the form (over web) I have at the end of the list one, two (or more) empty elements in list.
But I can´t delete this empty ones from the list in Forms Builder.
So my question:
how can I delete empty items in a popup list??
I try it with hit "del" button at keyboard or delete the set value for the item (I hope Forms Builder delete items without value). But all does not help.

ctrl+shift+<
or
On my german keyboard it is:
ctrl+< for deleting a line
ctrl+> (= ctrl+shift+<) for adding a new line
When adding the list elements and list values, make sure you only add the ones you need, if you need 3 elements in your list don't click on the 4th box in the property palette, this will add one more list element.
If you have a blank element and you want to remove it, the only way is to click on the property without clicking the "More..." button press on the "Inherit" button on the top of the property palette, this will reset the list elements and list values so you can add only the elements you want.
if you still have extra empty option then make sure of these:
1- make pop list item required
2- if its database item ... make sure you have yes on databse item and column name filled
3- make the column in table to have default value like '1'

hey perhaps you should try this ctrl+shift+,

Want to re-instantiate a component when navigating to same aux route

I have a list of items with Actions drop-down for each item in the left-section of page. I also have a right rail which displays a different component based on action type selected. I'm using aux-route to accomplish this.
One of the Action the user can take is "edit" where in a form is displayed to edit the metadata of the list item. While editing, user can click on + button next to some of the input field to add another input field dynamically.
Now my problem is, when the edit-form is open for a list item and I click edit on another item in the list, I wanted my edit-component to be re-instantiated.
Because the aux-route is same for all the list items for edit-action, edit-view is not instantiated once again. Is there a way to achieve it?
Right now fixed it with RouteReuseStrategy

TableView Enhancements

The TableView still leaves a lot to be desired. Does anyone have a more complex example of a TableView that you would like to share? Here's what I'm missing:
Insert and Delete row:
Possible solutions:
press TAB on the last cell and new row gets inserted automatically
right mouse button -> context menu -> insert line (or delete line)
a table footer with table navigation and insert/delete buttons (like MS Access)
keyboard shortcut
...
Insert and Delete should be either at the current row position or at the bottom of the table. Of course the new row should be highlighted.
Copying / Duplication of rows inside the TableView
Copy selected cells to the clipboard
(solution exists: copy multiple cells to clipboard, paste into table is missing)
Insert a row with default values
Type to Edit: I don't want to have to doubleclick on a cell first in order to edit it. When you type on a cell, the table should automatically go into edit mode.
Navigation options like e. g. TAB = cell in next column, ENTER = cell in next row
Filtering should be possible via components inside the tableview, not via components (TextField etc) outside of it. A filter indicator (like the sort indicator) would be nice.
Changing the visibility of columns should be convenient, not via multiple clicks of the tableview menu button (for every column you have to click the menu button separately to show the available columns). The tableview menu button should be customizable
(solutions exist with reflection and without reflection)
Row and column headers should be possible
Validation of cells, so that when you are in edit mode and enter text instead of digits into a numeric cell you get the option to cancel the edit mode and revert to the default value
A (fixed) table footer which could e. g. show the sum for each column would be nice
Freezing of columns (there's already a Jira task for this)
Some of these were covered partially years ago from what I've seen. But I couldn't get a clear How-To impression and maybe things have changed with JavaFX8.
In case someone likes to contribute to any of these mentioned features, please share your thoughts. Thank you very much.

How to set the default item in a drop down list and make it appear at the top?

I have a set of drop down boxes which are bound to the folder names in a folder (via getting all the directories, and then their lastnames, and then bind this array to the drop down list).
However, I also add an entry called "Please select..." after getting the array.
But is there a way to make this selection appear at the top of the drop down list (putting in something like dashes at the start and end don't work), and make it selected by default?
Thanks
If it is an ArrayList you could use myArray.Insert(0, "My Default Entry") which would make your default the first item in the list. Alternatively, you could set the SelectedIndex of the drop down to the index of your default item.

How do you make drag and drop always copy (never remove) in a Flex 4 Spark List?

Using the built in drag and drop features in Flex I can drag an item from one list and drop it into another list. But this removes the item from the first list. In my case I need to keep the items in the original list. So I need to always create a copy behavior for my users.
There is a property called, "dragMoveEnabled" that was set to "true".
From the documentation:
The description of this property is, "A flag that indicates whether items can be moved instead of just copied from the control as part of a drag-and-drop operation. If true, and the dragEnabled property is true, items can be moved. Often the data provider cannot or should not have items removed from it, so a MOVE operation should not be allowed during drag-and-drop."
When set to false or removed I'm getting the behavior that I want which is Copy always without having to also press the CTRL key for it to work.

click feature in Qt

I just want to clarify, weather the feature is present or not in Qt.
The scenario is like this,
I have a list view with items, I want to place the icon to the listview when the item is selected.
The selection I mean is, first time when I click item should be selected, next time if I click the same item then it should display some icon. Please note
It is not the double click. again if do select some other item same feature should continue
So is there any feature which handles this feature by default, any property or flag which I need to set to listview to behave like this or manual implementation
Is required for this.
No problem (: Now I understand what you mean... So if you click on an item it should be selected (for example highlighted in blue) and then when you click on this item again, an icon should be displayed.
I can't think of a regualar way to do this, there is no such flag or something.
The easiest way I can think of would be to store the index in a QList when you select it. And when you deselect it, you delete the index from the list. SO, when you click on an item you can check if it is in that list and if so you can display your icon.
Another way would be to create your own type of QModelIndex. Everytime, this index is selected, you set a bool like is_already_selected on true. When clicking on this item again you check this bool and then decide whether an icon should be displayed or not.
