* Use this ViewHelper to provide edit links to records. The ViewHelper will

*
* The uid must be given as a positive integer.
* For new records, use the :ref:`<be:link.newRecordViewHelper> <typo3-backend-link-newrecord>`.
*
* Examples
* ========
*
* Link to the record-edit action passed to FormEngine::
*
* <be:link.editRecord uid="42" table="a_table" returnUrl="foo/bar" />
*
* Output::
*
* <a href="/typo3/record/edit?edit[a_table][42]=edit&returnUrl=foo/bar">
* Edit record
* </a>
*
* Link to edit page uid=3 and then return back to the BE module "web_MyextensionList"::
*
* <be:link.editRecord uid="3" table="pages" returnUrl="{f:be.uri(route: 'web_MyextensionList')}">
*
* Link to edit only the fields title and subtitle of page uid=42 and return to foo/bar::
*
* <be:link.editRecord uid="42" table="pages" fields="title,subtitle" returnUrl="foo/bar">
* Edit record
* </be:link.editRecord>
*
* Output::
*
* <a href="/typo3/record/edit?edit[pages][42]=edit&returnUrl=foo/bar&columnsOnly=title,subtitle">
