    1. COI don't like this function. Why should parameter with no value should get the value of 'true'? Why not null? I think this design decision can lead to very subtle bugs. Also, why not handle the situation where parameter can have multiple values instead of selecting the 'last' value? Solution posted by David is much better.

    2. COIt is `true` so that one can check `if (params.redirect)` or similar. If you want to differ between `true` and other value, you would use `if (params.redirect === true)`. A `null` value wouldn't help in any way that I can think of. The reason I didn't do it like David is because I value consistency over flexibility. With his method I have to check if the value is a string or an array to use its value. In my opinion, it should always be a string (the `true` value converts to `'true'` which I think is fine), or always be an array. I chose string.

    3. COBy that account, if it was params.delete, it would be set to true and I will do something harmful. As you can see, coming up with example is easy. 'null' clearly specifies that no value exists and the decision is left to the caller what how he wants to interpret it. About multiple values, look at it this way. By eating up, you are making sure that either caller will spend time debugging why he is getting only one value OR later on come and modify the code. By returning the array upfront, caller will immediately know how to handle them. Discarding information is never good, IMHO.

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.
