[opencms-dev] about <cms:contentcheck> tag

[Alexander Kandzior]

Stephan,

Sounds like a good idea. As you probably know the implementations of the
contentXXX tags are in org.opencms.jsp in the CmsJspTagContentXXX classes.
If you could provide a patch against these that would be great.

FYT: It's likley that the "index" attribute of the "contentshow" tag will be
removed soon. The replacement mechanism is already in place, you will have
to <contentshow element="Title[0]"/> instead of <contentshow element="Title"
index="0"/>. 

Best Regards,
Alex.
