We have a site running on CMS5 R2 SP2 and on a pgae we have implemented a property as an editor (EditMode=true).
We have the following code in OnInit
PropertyLongString longString = new PropertyLongString();
// select chosen options or use EditorToolOption.All
longString.EditorToolOptions = EditorToolOption.All;
longString.Name = "MailTemplateStringProperty";
MailTemplateEditor.InnerProperty = longString;
Issue solved by EPiServer support.
This only happens in IE 8 (not if you run in compability mode)
First is Line 262 if(!widthAttr.specified)which should be if(widthAttr == null)
Second is 282 if(!heightAttr.specified)which should be if(heightAttr == null)
The same lines of code needs to be fixed in HyperlinkProperties.js in order to get linking on images to work.
