  I've tried to reproduce the bug:

  Could you send me a simple project that demonstrates this?

  I used a custom object in a generic collection as the data source. Could it be the source of the problem?

  I've tried to reproduce it in the Demo project (Demos\C#\Main); it has the business object datasource.
  

  private void CreateDataSources()
  {
    ...
    Category category = new Category("Beverages", "Soft drinks, coffees, teas, beers");
    category.Products.Add(new Product("Chai", 2757485250m));
    ...
  

  
  the product.UnitPrice is of decimal type. It works well, so I still need the demo from you.

  I cannot reproduce the error. I simply remove the field in the report, add a new field from exactly the same datasource and exactly the same object property.
  
  Then everything runs fine.
  
  So what is actually the source of the error? Is there a chance the same error will occur on the other reports?
  
  It's impossible to go trough all of them one by one.

  You old Text object had the highlight condition, right? Something like if Value > 100 then make text color red. In this case I can reproduce the error.
