Yes, our templates are fairly complex and the problem we are having is due to something that we are doing in our templates. We are using an HTML editor and when we add 1 text block we invoke the HTML editor to edit the text block and hide the GoJS Text Block. Once the user has finished editing we un hide the GoJS Text Block. That works fine for adding 1 Text Block but not for adding multiple Text Blocks. So we need to either not edit the Text Block when adding one or more or when adding 1 then use the HTML editor but if there are more than 1 do not use the HTML editor and do not hide the GoJS Text Blocks.
Thank you for all of your help. I think I will need to take it from here.
