For a reason I do not know, there is no toString() method on the formData.

In my project, we would like to transform the content of a formData to a String (debugging, logging, ...). Has someone already written such a utility?

I received a proposal from Beat Schwarzentrub.
Here the code (I let you deduce the corresponding form. It contains TableFields, use Templates...):
formData.setExampleNr(99L);

formData.getAge().setValue(34);
formData.getName().setValue("Peter Johnson");
formData.getValidity().setValue(new Date());
formData.getInfo().setValue(null);

int rowNum;
ProductsTable table = formData.getProductsTable();
table.clearRows();
rowNum = table.addRow();
table.setId(rowNum, 9837);
table.setProduct(rowNum, "Computer");
table.setAvailable(rowNum, true);

rowNum = table.addRow();
table.setId(rowNum, 3710);
table.setProduct(rowNum, "Keyboard");
table.setAvailable(rowNum, false);

PersonsTableRowData rowData;
PersonsTable table2 = formData.getPersonsTable();
rowData = table2.addRow();
rowData.setPersonId(364L);
rowData.setFirstName("Bob");
rowData.setLastName("Queen");

rowData = table2.addRow();
rowData.setPersonId(364L);
rowData.setFirstName("William");
rowData.setLastName("Peterson");

formData.getExtraGroupBox().getInfo1().setValue("Lorem");
formData.getExtraGroupBox().getInfo3().setValue("Lorem Ipsum\nDolore"); 


Here the output:
 ExampleFormData
	age:                 34
	exampleNrProperty:   99
	name:                Peter Johnson
	validity:            Wed Jun 04 18:53:27 CEST 2014 


It is a good thing that the output is sorted.

Several problems:
- No TableField support
- No Template support

There is a possibility to display null values if needed:
 ExampleFormData
	age:                 34
	exampleNrProperty:   99
	info:                null
	keyProperty:         null
	name:                Peter Johnson
	validity:            Wed Jun 04 18:54:01 CEST 2014 


I think the null handling should look at AbstractFormFieldData.isValueSet() [resp AbstractPropertyData.isValueSet()]. This way it is possible to distinguish between a value that is set to null and that is not set at all.
