xf:select1 bug: incorrect behavior with appearance="minimal"

Edgard Pineda-2
Hello OF developers,

I'm testing xf:select1 with OPS 3.5 M1, and I find a non-consistent
behavior between the differents appearance values, specifically with
appearance="minimal". Check it with the following example:

<?xml version="1.0" encoding="utf-8"?>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:xf="http://www.w3.org/2002/xforms"
      xmlns:ev="http://www.w3.org/2001/xml-events"
      xmlns:xsd="http://www.w3.org/2001/XMLSchema"
      xmlns:my="http://www.example.com/my">
 <head>
  <xf:model>
   <xf:instance id="first">
        <my:root><my:data>some text</my:data></my:root>
   </xf:instance>
   <xf:submission id="submit"
action="http://xformstest.org/cgi-bin/echo.sh" method="post"/>
  </xf:model>
 </head>
 <body>
Form:
  <xf:group ref="instance('first')">
    <p>root/data="<xf:output value="my:data"/>"</p>
    <xf:input ref="my:data"/>
    <xf:select1 id="sel1" ref="my:data" appearance="minimal">
     <xf:item>
      <xf:label>A</xf:label>
      <xf:value>A</xf:value>
     </xf:item>
     <xf:item>
      <xf:label>B</xf:label>
      <xf:value>B</xf:value>
     </xf:item>
     <xf:item>
      <xf:label>C</xf:label>
      <xf:value>C</xf:value>
     </xf:item>
    </xf:select1>
    <xf:select1 id="sel2" ref="my:data" appearance="compact">
     <xf:item>
      <xf:label>O</xf:label>
      <xf:value>O</xf:value>
     </xf:item>
     <xf:item>
      <xf:label>P</xf:label>
      <xf:value>P</xf:value>
     </xf:item>
     <xf:item>
      <xf:label>Q</xf:label>
      <xf:value>Q</xf:value>
     </xf:item>
    </xf:select1>
    <xf:select1 id="sel3" ref="my:data" appearance="full">
     <xf:item>
      <xf:label>X</xf:label>
      <xf:value>X</xf:value>
     </xf:item>
     <xf:item>
      <xf:label>Y</xf:label>
      <xf:value>Y</xf:value>
     </xf:item>
     <xf:item>
      <xf:label>Z</xf:label>
      <xf:value>Z</xf:value>
     </xf:item>
    </xf:select1>
  </xf:group>
 </body>
</html>

You can see the problem with the first select1 control: the value "A"
appears selected! and the other two are ok. The select1 with
appearance="minimal" should appear visually empty.
(Take this same example and run it with Mozilla XForms 0.7 in Firefox,
If you don't understand my explanation)
Test it again putting some other value of the other two select1
controls: the first select1 would not have to show a selected value!

Edgard.

Hi Edgard,

Yes, there is definitely an issue there, and we are aware of it. The
problem is that the HTML drop down doesn't have by default a choice
for "other" or "empty".

The Mozilla implementation adds this empty value to the drop down, and
then removes it from the drop down as soon as you select something
else. I am not sure I like this either: it means that if you select
something, you have no way of coming back to what you had before
(which was "nothing", because that choice is not there anymore in the
drop down).

Until we find a better solution, when you have an select1
appearance="minimal" which can be empty, add a first item with:

<xf:item>
    <xf:label>--Make a selection--</xf:label>
    <xf:value/>
</xf:item>
