  1. Recently we’ve looked at two methods to generate a “faux” subsummary to address a shortcoming of FileMaker native subsummaries… namely that in a multipage report you can have orphaned entries at the top of a given page with no indication of what parent entity they belong to. The methods were documented here: Conditional Summary Report […] View the full article
  2. Today we’re going to take another look at a challenge we discussed last time (in Conditional Summary Report Header)… namely how to cajole FileMaker into displaying a subsummary, or a reasonable facsimile thereof, at the top of a report page when items in the group begin on an earlier page.

    Conditional Summary Report Header

    Recently I received an email wondering… When printing a multipage report sorted by a sub-summary, is there a way to display the sub-summary heading on the following page when it breaks across two or more pages? There are various approaches one might take, and I actually buried one of those approaches inside an article + […] View the full article

    Thinking About JSON, part 3

    This a quick followup to last month’s part 2, because today I want to to dig a little deeper into JSONSetElement and take a closer look at the first argument: As I wrote last time… Part of what makes JSONSetElement so powerful is that it can be used both to create new entries, and to […] View the full article

    Thinking About JSON, Part 2

    This is a follow up to Thinking About JSON, Part 1. Last time we were primarily concerned with learning about JSON paths and structures, and reading JSON. This time around we’re going to look at creating and manipulating JSON. Demo file: winery-json.zip (If the above screen shot looks familiar you have a good memory, because […] View the full article

    Virtual List Reporting with JSON Arrays

    Acknowledgement: As always a huge thank you to Bruce Robertson, for inventing virtual list, and for many other contributions to the FM community over the years. Introduction As a follow up to my recent “Virtual List on Steroids” presentations at DIG-FM and dotFMP, today I want to take a fresh look at using JSON arrays […] View the full article

    Fast Summaries Re-revisited

    My recent “Virtual List on Steroids” presentation at DIG-FM, and the preparation of a revised version to give at dotFMP next week, has prompted me to reconsider certain assumptions re: optimizing performance both locally, and across a LAN and/or WAN. Specifically, there are two things we’re going to look at today. First, a way to […] View the full article

    Thinking About JSON, part 1

    I’ve been working on a couple large JSON projects over the last few months, and with the one year anniversary of FileMaker having built-in JSON capabilities just around the corner, this seems an opportune moment to share some reflections and opinions (some of which may contradict JSON-related opinions I have expressed previously). Demo file: json-sandbox.zip […] View the full article

    Custom Field-Based Value Lists

    Introduction Does this sound familiar? You’ve rolled out a solution that includes a single-record Settings table where authorized users can enter/update various system-wide settings, including one or more fields where the items will appear in popup menus… and then comes the inevitable question: Why don’t items in popup menus appear in the order I entered […] View the full article

    Exposed by Tableau

    Editor’s note: today we have a guest article written by John Weinshel, who has been quietly contributing to the FileMaker community for 20+ years. John’s thoughtful postings have helped developers at all levels of expertise, and I’m pleased to present his thoughts on Tableau here on FileMaker Hacks.

    Sorting on a Field Rep > 1

    Recently, in a virtual list report, I had a need to sort on rep number 2 of a repeating field called cell_text_r. FileMaker does not offer an obvious way to script a sort on a field rep > 1, and I had worked around the problem in the past by A. defining some special non-repeating […] View the full article

    Scrolling the Unscrollable

    Demo file: scrolling-the-unscrollable.zip Howard Schlossberg’s presentation on popovers (FileMaker 13 Popovers) has inspired me on multiple occasions… a favorite takeaway is the idea that you can have a scrolling check box set within a popover. The trick is to size the field as tall as necessary to display all the values (this is an extreme […] View the full article
