Spring 12 preview breaking change - has anyone else seen this?
Here's some code that works on a winter 12 dev org bug fails on a Spring 12 sandbox:
VisualForce controller:
public class Spring12Bug
{
private Map<String, String> m_entries;
public Map<String, String> Entries {
get
{
if(m_entries==null)
m_entries = new Map<String, String>{'A'=>'Red','B'=>'Green','C'=>'Blue'};
return m_entries;
}
}
public Set<String> getKeys()
{
return Entries.keyset();
}
}
VisualForce page markup:
<apex:page controller="Spring12Bug" >
<h1>Demonstration of bug</h1>
<apex:dataTable var="thekey" value="{!Keys}">
<apex:column headerValue="Entries" value="{!Entries[thekey]}" />
</apex:dataTable>
</apex:page>
On Winter 12 you get:
Demonstration of bugEntries
| Red |
| Green |
| Blue |
On Spring preview you get:
Visualforce Error
Map key null not found in map.
(Color changed for readability).
There is a workaround - to put the lookup in an OutputText tag inside of the column instead of using the Value attribute. But I figure someone should know about this bug as well.
Yes, this is a known problem. It should be fixed very soon.
