[TYPO3-dam-devel] RFC #9113: Render new image in RTE-enabled content when the file name is changed in DAM record

[Dan Osipov]

Stanislas,

I tried to apply your patch to a fresh install of Typo3 4.2.2-dev and 
DAM 1.1.0-dev from SVN.
I enabled the use of DAM in the RTE settings.
While creating a text element and attempting to add an image I was 
greeted with the following error:
Fatal error: Call to a member function getContextMenuCode() on a 
non-object in 
/srv/www/htdocs/t34-22/typo3conf/ext/dam/class.tx_dam_browse_media.php 
on line 139

After applying the patch, the error persisted.
Ideas?

Thanks for your work!

As a side-result of a previous patch, the value of the attribute is set to the value of the DAM media id when the image is inserted in the RTE-enabled field. If the current file name found in the DAM record is different from the one that was inserted in the RTE content, the src attribute of the img tag is updated. If the image was a magic image, a new reference and magic images are created (if no such files exist with the same file name, media id, and magic width and height). The custom attribute is then unset so that it does not show up in the frontend html. The page content cache must be cleared for the new image to be rendered.
