Key: JBSEAM-3916

Project: Seam
Issue Type: Bug
Components: EL
Affects Versions: 2.1.0.SP1
Reporter: Ian Springer
Priority: Critical
I have an expression:
#{MyBean.someMap['size']}
In my non-Seam JSF app, this expression was resolving to
MyBean.getSomeMap().get("size"). However, when I integrated Seam into my app,
the expression started instead resolving to MyBean.getSomeMap().size(), which broke my
app. This is occurring because SeamELResolver is ahead of javax.el.MapELResolver in the
CompositeELResolver resolver list, and its resolveInMap() function ensures a property
named "size" resolves to ((Map)base).size() This makes it impossible for me to
obtain the value of the element with key "size" from my Map via EL.
To solve this, I suggest changing SeamELResolver.resolveInMap() to the following:
private Object resolveInMap(ELContext context, Object base, Object property)
{
if ( !( (Map) base ).containsKey("size") &&
"size".equals(property) )
{
context.setPropertyResolved(true);
return ( (Map) base ).size();
}
else if ( !( (Map) base ).containsKey("values") &&
"values".equals(property) )
{
context.setPropertyResolved(true);
return ( (Map) base ).values();
}
else if ( !( (Map) base ).containsKey("keySet") &&
"keySet".equals(property) )
{
context.setPropertyResolved(true);
return ( (Map) base ).keySet();
}
else if ( !( (Map) base ).containsKey("entrySet") &&
"entrySet".equals(property) )
{
context.setPropertyResolved(true);
return ( (Map) base ).entrySet();
}
else
{
return null;
}
}
The only disadvantage of this is that if you actually are trying to get at map.size(),
there will be no way to do so if the Map happens to contain a key named "size".
However, in such a case, #{MyBean.someMap.keySet.size} or #{MyBean.someMap.values.size}
could instead be used to obtain the Map's size.

-----------------------------------------
This is a tough one because it could change functionality people are seeing now, but I
think it is fine because you can always use #{foo.size()}. Note that you can also call
#{foo.get('size')} as a workaround here.

The fix breaks other functionality. You can verify this with the examples/wiki/ start
page. The problematic line 83 in SeamELResolver.java:
private Object resolveInMap(ELContext context, Map map, Object property) {

}
You can't call containsKey() on the map in UIComponent:
return new AbstractMap<String, UIComponent>()
{
@Override
public Set<Map.Entry<String, UIComponent>> entrySet()
{
throw new UnsupportedOperationException();
}
Test code:
<h:outputText id="foo" value="FOO"/>
<h:outputText value="#{uiComponent[foo]}"/>
With this stacktrace:
Caused by: java.lang.UnsupportedOperationException
