Finally we get success in using the following code.
{code}
<h:graphicImage value="/images/closeButton.png"
styleClass="closeButton"
onclick="closeTab('#{tab.id}');event.stopPropagation();"
immediate="true" />
{code}
{code}
<!-- -->
<!-- CLOSE TAB -->
<!-- -->
<a4j:jsFunction id="closeTab" name="closeTab"
action="#{desktopTabController.doCloseTab}"
render="menu-opened-tabs,desktopTabPanel">
<a4j:param name="tabId" assignTo="#{desktopTabController.closeTabId}" />
</a4j:jsFunction>
{code}
The function event.stopPropagation() instead of Event.stop(event).
The NPE is a contextual bug : it may depend on :
- Having or not having set the activeItem
- We have also return an Collections.unmodifiableCollection(xxx) of our
dynamic tabs.
- Race condition : because at the begin of the project, the same code trigger
an NPE and now, it does not. So, is there an impact about having an empty
dynamic tabs versus tabs with some content ? Deletion also triggers NPE in some
circumstance (not all the time).
RichFaces should guide the users on how build robust dynamic tabs that supports
also dynamic close/deletion. What are the best practices and what are the buggy
scenarios. There is different ways to build dynamic tabs, some are better than
other, some are better suitable for a specific situation than other and etc.
It would be good that richfaces give us the closeTab as a built-in feature and
allow us to decide to close or not closing the tab based on the user context (I
mean, user is editing some field, do we need to cancel the modification...)
