    1. COThanks to all. It seems this fundamental feature is lacking in the standard and must be added in some way. Rather than introducing new syntax, mimicking Perl or PHP, what do you think about writing a macro that wraps make-hash-table and adds the option :initial-contents, the same option supported in the standard by, e.g., make-array? I think this won't probably be very efficient, since content would be specified by an alist that has to be traversed, but it is at least more consistent with Lisp syntax.

    2. COThanks Lisp hacker! It makes sense, I forgot the output from print is readable! All makes sense in Lisp and "there is always the right way to do it" :) Anyway, the standard has some shortcomings and we cannot change it :( For instance about printing line numbers I don't have a clue.

    3. COYes, thanks, I know, a good reason for that is that macros are harder to write and debug. But if I write a function in this case, I cannot call it with #. At least in ECL it tells me it is undefined. I think this is the effect of #. that is any user defined function is not available at read-time. I wonder if a macro wrapper can be written that allows one to fully configure make-hash-table while adding an :initial-contents keyword parameter. That would "add this feature to the standard" :)

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.
