-----------------------------------
Summary: <a4j:support> does not override literal event handlers without
EL-espressions
Key: RF-13152
URL: https://issues.jboss.org/browse/RF-13152
Project: RichFaces
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: component-a4j-core
Affects Versions: 3.3.3.Final
Environment: JSF 1.2
Reporter: Nicholas Oxhøj
Priority: Minor
If I nest an <a4j:support> inside a component which also has an inline event
listener whose text doesn't contain any EL-expressions, the <a4j:support>
_won't_ be executed. For example
{code}
<h:inputText onchange="alert('Inline listener')">
<a4j:support event="onchange" onsubmit="alert('a4j:support
listener')" />
</h:inputText>
{code}
will show an alert with "Inline listener" and *not* perform the
<a4j:support>.
If you add _any_ EL-expression to the inline event listener, the <a4j:support>
_will_ be executed instead. For example
{code}
<h:inputText onchange="alert('Inline listener')#{''}">
<a4j:support event="onchange" onsubmit="alert('a4j:support
listener')" />
</h:inputText>
{code}
*will* show an alert with "a4j:support listener".
I am not exactly sure how a UIComponents "attributes" and "value expression
bindings" are supposed to work together according to the JSF spec, but the problem
here seems to be that when the inline listener doesn't contain any EL-expressions, it
is stored as an "attribute", but the <a4j:support> is stored as a
"value binding expression". Later, during page rendering,
HtmlInputText#getOnchange() will first look for an attribute called "onchange"
and return that if found. Only if an attribute is not found, it looks for a "value
expression binding" and returns that.
