Good day !
Sorry for my English.
The problem when switching between tabs "Search form" "order" and others. This occurs in "form & content", "list & search". The system does not change the contents of the block "layers", and opens a page with the content of the link :
administrator / index.php?option=com_cck&view=search&layout=edit2&id=77client=order&layer=fields&format=raw.
Long tormented , but can not beat this problem .
