Issues with custom theme

[Clay Banks，修改在10 年前。]

An issue has occurred for no reason in my Liferay 6.2 portal running on Oracle 12c WebLogic. I can no longer edit, or even see my web content in Edit mode-content is not even visible.

I'm getting this stack trace whenever I access my home page, and my web content is displaying oddly:

We have the same issue with Liferay 6.2 EE SP2 on WebLogic12cR2 and Solaris 11.
We did not find any sollution yet .

Hi,

as a quick workaround you can try if disabling the ETAG-filter (com.liferay.portal.servlet.filters.etag.ETagFilter=false) is solving this issue.

try adding below in weblogic.xml
<optimistic-serialization>true</optimistic-serialization>
<prefer-web-inf-classes>true</prefer-web-inf-classes>

HI Could you say where to set this property? portlet.properties file?

And I have already the above two properties in my weblogic.xml file

[Oliver Bayer，修改在10 年前。]

Hi,

add this line to portal-ext.properties.

Hi all.

Normally it is an inconsistent status many times related with the deployed plugins. I noticed a similar error using portlets sharing services with other portlets and the seconds don't have declared the dependencies, so the deploy was not in order causing similar errors.

If this is your case you only have to add the dependencies in the liferay-plugin-package.properties of the plugins that use external services in others plugins, eg:

required-deployment-contexts=\
my-portlet,\
other-portlet


I hope this can help you, but if this is not your case, take a look at the server log an look for deployment errors during the start-up

Best regards.
