I have placed dynamic content in MainBody on some pages. I've noticed that sometimes when I click Edit on them, the editor is empty. I have to start from scratch and select which dynamic content to use and then set all the properties. What I expect is to have the correct dynamic content already selected and the current values of its properties displayed.
Have anyone else experienced this? Is it a known bug in EPiServer or am I doing something wrong? It's basically just user controls with the DynamicContentPlugIn attribute.
Yeah, I've experienced this (you'll also find a couple of bugs in the bug list). Some I think are fixed in the hotfix for EPiServer CMS 6 R2.
Try using Internet Explorer, not sure if dynamic content is fully supported by ither browsers. :(
