Nicholas Oxhøj updated RF-13152:
--------------------------------
Attachment: test.xhtml
Example showing the erroneous behavior.
> <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
> Attachments: test.xhtml
>
>
> 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.
