Description clutz 2006-10-04 10:13:40 UTC
The following macro creates a new DropDown-Field in a textdocument and sets its
itemlist to the elements ["foo", ""]. After setting the SelectedItem property to
"", the DropDown displayes "foo" which is not the whished element.

So it seems to me that an emty string is treated like a invalid element, but I
can't see why empty string should not be allowed within dropdown fields. Also
this behaviour is even not documented in the idl and it is inconsistent with the
behaviour of other TextFields (e.g. InputField) which allow empty string. I
think one of the following two things should be done:

1) document the behaviour that an empty string is invalid in the idl-docu that
describes the properties "Items" and "SelectedItem"


2) change the code in a form that an empty string is not longer a invalid item
and is accepted and displayed correct.

here the code:

Sub dropDownBoxMissbehaviour
	dim items(2) as String
	items(0) = "foo"
	items(2) = ""

	doc = ThisComponent
	dd = doc.createInstance("")

	dd.Items = items()
	dd.SelectedItem = ""

	doc.Text.insertTextContent(doc.Text.Start, dd, true)
End Sub

in my code there's one mistake:

the statement 'items(2) = ""' should be 'items(1) = ""'. But even after
correcting the mistake, the behaviour is the same, so the ticket is still valid.

Sounds more API like -> cn
Comment 4 chne 2006-10-18 11:06:36 UTC
cn->fs: there seems to be an issue. The IDL sayes to "select"

 The selected item. If no item is selected this property contains an emtpy
string. If this property is set to a value not present in the items of the
dropdown field it is invalidated, i.e. it is set to an empty string.  

But I get always "foo", regardless of invalid or empty string.

cn->fs: for you
Comment 6 Frank Schönheit 2006-10-18 11:39:48 UTC
that's no form control, that's a text field.
