Javascript error: Cannot read property 'preventNotification' of undefined
Junior Member Mensajes: 81 Fecha de incorporación: 2/07/11 Mensajes recientes
System: Windows & Linux
Release: Bundle Liferay 6.1GA1 / Tomcat 7
Hi,
I developped a custom 286 portlet, it works pretty well but currently i get this javascript error in the browser console, for each window where this portlet is set up:
Uncaught TypeError: Cannot read property 'preventNotification' of undefined
The error relates to the resource "<Liferay Root>/html/js/everything.jsp:3", wich i guess is dynamically built. Although the portlet works, there are few issues that may be caused by this error: for example, if i minify a portlet window and then refresh the page, the restore option won't work, i have to maximize the window to "wake up" it.
Please could someone give me clues about this javascript error?
Thanks!

Hi,
the message comes from "portlet.js" when Liferay inject html
How do you populate your portlet?
Maybe that is the reason why every new portlet from sdk adds

I forgot to say that my problem have a slight difference because to me this happens with RSS Portlet that come with Liferay 6.1.
I will see what you say in RSS Portlet source code.

I can reproduce it with a RSS Portlet installed.
Lowest layer of call stack is "IO._rS" from "io-base.js" (onReadyStateChange event handling),
but i can't directly see a solution to this problem.
But i think a browser who runs with production code should never caught exceptions.
Don't know if IE or other can handle this, i use Chrome and can set this in the debugger.
Are there side effects in your case?
Keep on coding

I solve the problem, in the file liferay-portlet.xml in \tomcat-7.0.23\webapps\ROOT\WEB-INF.
On rss portlet configuration you have this:
<portlet>
<portlet-name>39</portlet-name>
<icon>/html/icons/rss.png</icon>
<struts-path>rss</struts-path>
<configuration-action-class>com.liferay.portlet.rss.action.ConfigurationActionImpl</configuration-action-class>
<portlet-data-handler-class>com.liferay.portlet.rss.lar.RSSPortletDataHandlerImpl</portlet-data-handler-class>
<preferences-owned-by-group>true</preferences-owned-by-group>
<use-default-template>false</use-default-template>
<instanceable>true</instanceable>
<private-request-attributes>false</private-request-attributes>
<private-session-attributes>false</private-session-attributes>
[b][size=6]<render-weight>0</render-weight>[/size][/b]
<header-portlet-css>/html/portlet/rss/css/main.css</header-portlet-css>
<css-class-wrapper>portlet-rss</css-class-wrapper>
</portlet>
You need to change to:
<portlet>
<portlet-name>39</portlet-name>
<icon>/html/icons/rss.png</icon>
<struts-path>rss</struts-path>
<configuration-action-class>com.liferay.portlet.rss.action.ConfigurationActionImpl</configuration-action-class>
<portlet-data-handler-class>com.liferay.portlet.rss.lar.RSSPortletDataHandlerImpl</portlet-data-handler-class>
<preferences-owned-by-group>true</preferences-owned-by-group>
<use-default-template>false</use-default-template>
<instanceable>true</instanceable>
<private-request-attributes>false</private-request-attributes>
<private-session-attributes>false</private-session-attributes>
[b][size=6]<render-weight>50</render-weight>[/size][/b]
<header-portlet-css>/html/portlet/rss/css/main.css</header-portlet-css>
<css-class-wrapper>portlet-rss</css-class-wrapper>
</portlet>

The above is NOT a fix even if it solves the immediate problem.
Setting the render-weight to anything higher than 0 prevents the portlet from being loaded asynchronously (in parallell). This problem (or at least similar) also exists with 6.0 releases, see LPS-21886

I am seeing a similar Javascript error with the chat portlet. This actually prevents you from initiating a chat session with a desired friend. You can see Online Friends, but if you click on them to chat, the chat window does not come up (because of these prior Js errors).
In Chrome, I receive:
Uncaught TypeError: Cannot read property 'preventNotification' of undefined everything.jsp:3
In Firefox, I receive:
j is undefined
I noticed in a subsequent post Antonio mentioned changing the render-weight of the rss portlet in liferay-portlet.xml. Not sure what exactly this does and if a similar fix could apply to the chat portlet.
Any help/insight would be appreciated.
