[TYPO3-core] RFC: bugfix #6932 Unlike the default preview language, fields of additionalPreviewLanguages are shown if they are empty

[Helmut Hummel]

Hi,

another little language issue...

This is a SVN patch request.

Branches: 4_1, trunk

BT Reference: http://bugs.typo3.org/view.php?id=6932

Problem:
If a field of a translated record does contain a value in the default
language, a preview of this default language field is shown. If the
field in default languge is empty, nothing is shown.

Solution:
Like for default language, check if the field in
additionalPreviewLanguages contains any data.

This is done by a simple check in function renderDefaultLanguageContent:

if (strcmp($dLVal,''))

But this check is missing for additionalPreviewLanguages.

Solution:
Add this check for additionalPreviewLanguages, too.
