[Texo] Annotation for array of TEXT EString values [message #1707732]

I have an EAttribute which is an array of EString values. I need each value in the db to be TEXT since the length of the string values is often > 255 chars.

I added an annotation Annotated EClass - Annotated EAttribute - ORM Annotation - Basic - Column (set Column Definition to "TEXT"). When I have Texo generate code it creates:

	
@ElementCollection()
	@Column(name = "T_element")
	@Column(columnDefinition = "TEXT")
	@CollectionTable(joinColumns = { @JoinColumn(name = "NotificationEvent_id") }, name = "NotificationEvent_Messages")
	@Basic()
	private List<String> messages = new ArrayList<String>();

I believe what Texo should generate is a single Column line as such:

@Column(name = "T_element", columnDefinition="TEXT")

Is this a bug or am I not annotating correctly?

Hi Mike,
Texo/ORMs assume that a list of values should be stored in a separate table.
So in this case you will get a table with a text column to store the list of values.

So it is not really a bug. If you want to serialize/persist a list<string> in a single column then you need to dive into
customer persisters I guess, this will be specific for the ORM you are using I guess.
