Studio Pro suddenly cant load document template to edit
0
Hi, I’ve come across a quite frustrating bug with document generation. I’d gotten quite far with creating a document template but, as I added another table, the below error occurred. System.AggregateException: One or more errors occurred. (Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')) ---> System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index') at System.Collections.Generic.List`1.get_Item(Int32 index) at Mendix.Modeler.DocumentTemplates.Documents.Widgets.Tables.MxTable.CheckFullyMergedColumns(IProblems problems) in

Is there a known way to fix this? The template editor shows the following when I try to open the template: I’m using 9.18.0
