readCommonProperty

public java.lang.String readCommonProperty(CmsObject cms,

Description copied from interface: I_CmsTemplateContextProvider

Gets the value which should be used instead of a property which was read from the template resource.

This is needed because before template context providers, it was common to store template-specific configuration in a property on the template JSP. Since template context providers make the result ambiguous, this method is intended as a replacement.

Specified by:

readCommonProperty in interface I_CmsTemplateContextProvider

Parameters:

cms - the CMS context to use

propertyName - the name of the property

fallbackValue - the value to return if no value is found or an error occurs

Returns:

the common property value

Throws:

CmsException - if something goes wrong
