Body
Because data.length is only 2 in both cases Further explained: Each object contains multiple values, however, you're not calling for the length of those objects. data.length = get me the count of children in data (not grandchildren and cousins and neices and nephews) JUST CHILDREN. In both of those cases, regaurdless of what the objects are, there is 2 of them in data, thus the length = 2 To furter: It doesn't matter what those objects are, heck you could have one string and one child array, that would still return 2 because it would be 2 objects inside the object we're asking for length on <blockquote> UPDATE to answer second question brought up </blockquote> The reason for access is simple, in the first instance, your children are typical Objects, as seen in your example: <pre><code>data = [ // These two CHILDREN are Typical Objects Object { code="6", id="1073148", key="82628835"}, Object { code="17", id="2073140", key="83628837"} ] </code></pre> Thus you can access obect 1 as data[0]. HOWEVER in your second example, the children are ARRAY Type Objects, thus, each child could have multiple values. For Example: <pre><code>data = [ [Object { code="6", id="1073148", key="82628835"}], [Object { code="17", id="2073140", key="83628837"}] ] // Your example here has 2 children but each child is an ARRAY type Object, // Each array has one child which is the object in each one // thus you can call data[0][0] & data[1][0] // Could also be data = [ [Object { code="6", id="1073148", key="82628835"}, Object { code="17", id="2073140", key="83628837"}] ] // in this later case, there is only one child // this one child, like in your example, is an ARRAY, but in this later example, // it has TWO children of its own // thus you can call data[0][0] and data[0][1] </code></pre> As you can see, your second example does NOT have two children OBJECTS, instead it contains 2 Children ARRAYS that each contain one child object. Thus the need to get object 1 becomes <code>data[0][0]</code> Where data[0] is getting the first array child and the second [0] is getting that arrays child object Get it? If not just let me know!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
