Notice: Undefined property: JAdministrator::$JComponentTitle
I received the following error message:
Notice: Undefined property: JAdministrator :: $ JComponentTitle in xxxxxxxxxxxx\j257_agp\ administrator\modules\mod_title\ mod_title.php on line 13
I'm running Joomla 2.5.7 in local development server with Apache 2.2.22, PHP 5.4.0, MySQL 5.5 on Windows Vista Home Premium (32 bit)
It possible that this error message appears me because my site is not in the Web, or you need to correct the code?
Component name in manifestfile has to be conform
In Joomla 1.6 the component name specified in the manifest file has to follow the pattern 'com_componentname'. So here it should be
It will matter at least in the menu manager, where I discovered this problem.
Archive is created for version 1.6 instead of 2.5
In the section "Packaging an installation zip file", archive file offered as an example (located here: http://joomlacode.org/gf/download/frsrelease/11394/58225/com_helloworld-1.6-part01.zip) contains an XML file which has a line:
<extension type="component" version="1.6.0" method="upgrade">
<extension type="component" version="2.5.0" method="upgrade">
which should be fixed, I guess.
