[jira] Created: (COCOON-1915) Nullable value with additional String
or XMLizable in JavaSelectionList
Nullable value with additional String or XMLizable in JavaSelectionList
-----------------------------------------------------------------------
Key: COCOON-1915
URL: http://issues.apache.org/jira/browse/COCOON-1915
Project: Cocoon
Issue Type: Improvement
Components: Blocks: Forms
Affects Versions: 2.1.9
Reporter: Rolf Metternich
Priority: Trivial
Setting a text for the nullable-Value as String or XMLizable programmaticly by using setNullText(String nullText);
Also you can set the nullText in the definition of the selectionlist.
Example:
<fd:datatype base="long"/>
<fd:selection-list>
<fd:null-text>
<i18n:text>please-select</i18n:text>
</fd:null-text>
<fd:item value="1"/>
<fd:item value="2"/>
<fd:item value="3">
<fd:label>three</fd:label>
</fd:item>
<fd:item value="4"/>
<fd:item value="5"/>
</fd:selection-list>

[jira] Commented: (COCOON-1915) Nullable value with additional

Hi Mark!
Maybe it is possible to use the items with value="". I didn't test it and, of course, I hadn't this idea.
For my problem: I fill a JavaSelectionList with database values and offer sometimes, in programmatically context, not to select an item. I do this by 'setNullable(true)'. When I set nullabel to true, the sax generation builds an item with value="" and no label. I wanted to have this null-item with an label like 'all' or something else.
This way, i can toggle between setNullable=true/false dependend on other values in the form (perhaps Ajax), without building the SelectionList again.
The improvements are also made in the JavaSelectionListBuilder and the first example is only done for this.
I hope, you can I understand, why I did it. Do you have another solution for this problem?

Hello Mark!
Maybe your solution shows the same data in the form, but the 'null-text' tag is made for supporting the 'nullable' attribute in the selection list.
So you can differ between normal items and the text-value for the nullable element and set the null-text by software.
This is useful for sax generation in the AbstractJavaSelectionList where the 'nullable' attribute is tested.

----------------------------------------
Hi Rolf, I'm still not sure that I get it :-). I understand 'nullable' for enum selection lists, but I don't see how it makes sense for ordinary text-based lists when (a) the empty value translates to null on submission, and (b) you can specify a label for the empty value using current mechanisms.
You said "This is useful for sax generation in the AbstractJavaSelectionList where the 'nullable' attribute is tested", but the purpose of generateSaxFragment() is just to generate the form markup... so if you can already effect that same markup without a new mechanism, where is the need for that new mechanism?
IOW... can you give an example of something you need this <null-text> for that you cannot do with <item value="">, i.e. specifically how would it not work to do it that way?
thx,
- Mark

----------------------------------------
With regard to
<fd:null-text>
<i18n:text>please-select</i18n:text>
</fd:null-text>
Does that do anything different than what you can already do using this?:
<fd:item value="">
<fd:label>
<i18n:text>please-select</i18n:text>
</fd:label>
</fd:item>
