-------------------------------------
Summary: s:selectItems noSelectionLabel causes errors without
using ui:debug
Key: JBSEAM-5052
URL: https://issues.jboss.org/browse/JBSEAM-5052
Project: Seam 2
Issue Type: Bug
Components: JSF Controls
Affects Versions: 2.2.1.CR1
Environment: JBoss 6 M3
Reporter: Andrew Wheeler
Assignee: Marek Novotny
Fix For: 2.3.0.CR1
When a selectOneMenu has no items other than the no selection option it does
not render the option value as
org.jboss.seam.ui.NoSelectionConverter.noSelectionValue. In this case the there
are no values in person.images.
<h:selectOneMenu id="portrait" value="#{person.portrait}">
<s:selectItems value="#{person.images}" var="i" label="#{i.annotation}"
hideNoSelectionLabel="false" noSelectionLabel="Select a portrait..."/>
<s:convertEntity/>
</h:selectOneMenu>
This renders:
<select id="person:portraitDecoration:portrait"
name="person:portraitDecoration:portrait" size="1"> <option
selected="selected">Select a portrait...</option>
</select>
The result is that any form submit causes a java.lang.NumberFormatException
with message: "For input string: "Select a portrait...""
I have debugged a little and I can see that the converter is not firing when
rendering the page. It does however fire for other selectOneMenu items on the
page that have one or more items.
A similar and perhaps related issue is referenced in the JBoss Forum.
