How are multiple values stored in properties (in sequence or random order)?

Dear all, I'm trying to store some pair array data in a custom data type. The custom type represents a group. and within this group, it has many members. The members' names and genders are stored within this custom type. The xml file is like: <type name="demo:group"> <parent>

Hi Sun,

I have created a custom model and it uses a muli-select list for input of the values. In this case, I have observed that the items are always stored in the sequence in which they are selected i.e. from top of the list towards the bottom.
In your case also, it should be in the same order, so there should not be any variation in the relation between the two columns.

Hope it helps you

Many thanks for the test.

In my test and observation, those appeared in sequence as well. The only reason I raise this question was to understand how is such sequence structure storaged in Alfresco. I.E. is this sequence order guaranteed or it just happened in those occasions that you and I tested? Otherwise, it cannot be relied on.

Yes, you can rely on multi-valued properties returning in a consistent order. Associations, on the other hand, are not always returned in the same order.
