what ? just me who have this bug or what .. or no one using matrix datatype ?!
now found also when i add new column will not be show on when edit object !
Another thing ... for user site I have created overrided template for matrix, but this template also is show in admin site, but I didn`t write anything to admin site override settings , and when i remove the template form my design it loading the stander design template for matrix !!
For the template viewing I found this setting in site.ini effect just the matrix template 'AdditionalSiteDesignList' , so when the value is mydesign the matrix template is loaded from mydesign !
