Brian Leathem created RF-13165:
----------------------------------
Summary: The rowclick event of the rich:dataTable is not
recognized as a valid server-side event during an ajax postback
Key: RF-13165
URL: https://issues.jboss.org/browse/RF-13165
Project: RichFaces
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Components: component-tables
Reporter: Brian Leathem
Fix For: 5-Tracking
An embedded _<a4j:ajax>_ tag in an extendedDataTable with the event rowclick_
does not work. The relevant code snippet:
{code}
<a4j:ajax event="rowclick" render="shippingEditForm"
listener="#{shippingEdit.setId(shipping.id)}"/>
{code}
This *should* work. A google search quickly shows one how many people expect it
to work. I dug in to find out why it doesn't work:
When a HTML element triggers an ajax event, a check is performed on the
server-side to see if the HTML element that triggered the event is the JSF
component that is being decoded. This is done in this line of code:
https://github.com/richfaces/richfaces/blob/master/framework/src/main/java/org/richfaces/renderkit/RenderKitUtils.java#L511
{code}
if (behaviorSource != null && behaviorSource.equals(clientId)) {
...
{code}
Before the request is sent to the server, we check if the originating element
of an event is from a component, and "re-target" it if not (see:RF-12616,
RF-12715). This is done in these lines of code:
https://github.com/richfaces/richfaces/blob/master/framework/src/main/resources/META-INF/resources/richfaces.js#L677
{code}
if (this.id && sourceElement.id.indexOf(this.id) == 0) { //
otherwise parent element is definitely not JSF component
var suffix = sourceElement.id.substring(this.id.length); //
extract suffix
if (suffix.match(/^[a-zA-Z]*$/) &&
isRichFacesComponent(this)) {
parentElement = this;
return false;
}
}
{code}
This re-targeting works well, as for the most part elements DOM ids within
components use the _#\{clientId}Qualifier_ syntax. However this breaks down
with table rows, where the ":" separator is used. This is the same separator
used to separate JSF component id's in the _clientId_. For example, a table
with the _clilentId_ "_form:edt_" will have rows with DOM id "_myForm:edt:5:n_".
So we need to fix the client-side re-targeting to work for table rows.
