Piotrek Karaś	Friday 11 December 2009 2:44:29 am Hello, I've got the following problem: an image alias has once been generated with attribute_view_gui template operator, but then the image alias file (jpg) has been removed for some reason from the file system. From that moment on, attribute_view_gui is unable to regenerate the file because the database tells it that the alias exists. What would be the best/easiest way (in PHP) to force regeneration of the missing alias jpeg file? I did some tests and is seems that it's enough to remove alias declaration that is stored in ezimage content object attributes in form of alias XML. However, the XML (eZImageAliasHandler I suppose) doesn't seem to provide any API for single alias removal (or even removeAllButNotOriginal ;) ). However, if I remove given alias XML node, the alias gets regenerated, as required. Any ideas greatly appreciated!
