You can copy and paste stuff in FileMaker: Layouts, script steps, scripts, custom functions, value lists, fields and table definitions. Each time FileMaker puts a XML on the clipboard, but you can't see it. It is kind of hidden, so FileMaker can find it for pasting. But you can't just paste it to your favorite text editor.
With MBS Plugin 15.4 we change this. Our plugin monitors when FileMaker goes to back or comes to the front and updates the clipboard:
If the clipboard has FileMaker's XML, we copy the XML into the text section, so you can paste it in a text editor.
If the clipboard has text, which is valid XML for FileMaker, but not yet the section that FileMaker looks for, we copy the XML into the right section. Then you can paste in FileMaker as usual.
You may wonder why we do this? Well we like to edit the XML in a text editor like BBEdit and then put it back.

With MBS FileMaker Plugin 15.3 we allow you to dynamically register custom function via plugin functions. Yes, make your own functions on the fly and use them in all your database files. Instead of defining custom functions in FileMaker directly and then copying & pasting them to other files, you can store them in records and register them at startup.
Each function gets the following:
ID
It needs an unique ID which is what FileMaker internally uses to find the function. Please use an ID >= 3 and assign them yourself to the functions.
Name
An unique name, which doesn't match a FileMaker function or an existing custom function. Just like names in FileMaker, you may only use a subset of characters, e.g. no brackets.
Prototype
The function needs to have a prototype for display in the function list.
The prototype gives our parameters a name for the variables.
Expression
You pass the calculation to evaluate. This is a FileMaker calculation just like in a custom function in FileMaker. You can use the names defined for variables in the prototype.
Independent of parameter names, you can always use Plugin.CustomFunctionParameterCount to query the number of parameters and then query the value with Plugin.CustomFunctionParameter function. This allows your function to take a variable number of parameters.
Since parameters are stored per thread, you may prefer to read any variable parameter values into local variables before doing any recursion.
Min/MaxParameter
You can define a minimum and a maximum number of parameters. Both are optional and default to 0 for minimum and no limit (-1) for maximum parameters.
Flags
For MBS Plugin 15.4 we add optional flags. Default is 0 here for compatibility with older versions. You can pass 1 to enable the use of JavaScript here. Later we added 2 for using JavaScript with WebKit instead of Duktape.
Then we added the flag 4 which allows to remember values from one call to the next. Great for using multiple calls within a script and have one custom function take data, parse it and remember it, so other custom functions can read this data.
Once registered somewhere, you can use the functions everywhere in all calculations.

For MBS FileMaker Plugin 15.3 we added iOS support to the ListDialog functions in addition to MacOS and Windows.
You can just use it anywhere in a script or calculation to have the user pick something from a list. For example you can fill the list with a text field holding all options. or you use SQL to either go over values in a table to collect them (with distinct option) or you use FileMaker_ValueLists in SQL to query a value list content.
Here a small example script:
Set Variable [ $r ; Value: MBS("ListDialog.Reset") ]
Set Variable [ $r ; Value: MBS("ListDialog.SetPrompt"; "Please select your country:") ]
Set Variable [ $r ; Value: MBS("ListDialog.SetShowsFilter"; 1) ]
Set Variable [ $r ; Value: MBS("ListDialog.SetAllowMultipleSelection"; 0) ]
Set Variable [ $r ; Value: MBS("ListDialog.AddItemsToList"; PlaceHolder::Countries) ]
Set Variable [ $r ; Value: MBS("ListDialog.ShowDialog") ]
Set Field [ PlaceHolder::Result ; $r & ": " & MBS("ListDialog.GetSelectedTitle") ]
There are a couple of differences.
- iOS list is one column. Second column content would go into a second line below.
- There are no column headers, but groups exist.
- There are no checkboxes for iOS
- For iOS we show the dialog full screen, so no positioning.
- There is no window title on iOS.
- iOS has no window widgets, so no close box. You need to have at least a button to close the dialog.
Please try the functions and let us know if they work well for your iOS application made using the FileMaker iOS SDK.
Noch einen Monat: Vom 14. bis 17. September 2025 findet die nächste deutschsprachige FileMaker Konferenz in Hamburg, Deutschland statt. Das JUFA Hotel Hamburg HafenCity liegt direkt neben dem Ausgang der U-Bahn Station HafenCity Universität, nur drei Stationen vom Hauptbahnhof via U4, so dass sich die Anreise per Bahn empfiehlt. FileMaker Anwender und Entwickler können ihre Teilnahme buchen.
Wir sind mit drei Vorträgen dabei:
- Christian Schmitz: MBS Sponsored Session zu neuem in 2025
- Stefanie Juchmes: Keine Angst vor Scripten und Funktionen
- Stefanie Juchmes: Scripte auf dem Server
Weitere Vorträge im Konferenzplan.
Die Veranstalter vom Verein FM Konferenz erwarten auch 2025 rund 120 Entwickler, Anwender, IT-Fachleute und Entscheidungsträger aus Wirtschaft, Bildung und Verwaltung. Rund um 24 Fachvorträge und Workshops wird es viel Zeit zum Vernetzen in den gemeinsamen Pausen und beim Abendprogramm geben.
Weitere Konferenzen hier.

For the next version we include round corners for the iOS SDK with the Window.SetRoundCorners function in MBS FileMaker Plugin.
You can call Window.SetRoundCorners just after showing the card window. Our plugin will look for the top most card window and apply the corners.
Since there may be a short delay before FileMaker actually creates the card and shows it, we need to wait a bit. In our sample script, we perform a short script pause. Then even if FileMaker animates the card, the plugin can find it and apply the corners.
Here is a sample script for iOS:
New Window [ Style: Card ; Name: "test" ; Using layout: “PlaceHolder” ]
Pause/Resume Script [ Duration (seconds): ,1 ]
Set Variable [ $r ; Value: MBS( "Window.SetRoundCorners"; 0; 12) ]
If the pause is too short, the card may not be yet there and we may apply the corners to the main view.
To use this feature on iOS, you need to use Xcode to build yourself a branded FileMaker Go clone with our plugin embedded in the app. With a pure FileMaker Go this would not work.
For desktop and iOS you can just have the pause and the Window.SetRoundCorners call in script. If the plugin is not installed or activated, the call will just do nothing.
In MBS Plugin 15.3 you can use the function for MacOS and Windows in FileMaker Pro already. With version 15.4 we add iOS support.
Please try the function and let us know if you have questions.
