Again working with widgets, this bug or feature – JavaScript code is only copied to the PDF if it’s used in a \goto – is still open.

feature but you can say \startJSpreamble FOO used now ...

Additionally, I found that \setupfields (plural) doesn’t work, I need to setup all formatting in each \setupfield.

fields have always be special as there can be thousands of fields their settings are saved in a special way (in order not to run out of memory / hash space then) ... kind of mkii compatible

I found another issue with workaround: http://wiki.contextgarden.net/Tabulate#Itemization_or_framed_objects_inside_... You need to set "\tabulatesplitlinemode \plustwo" if you put widgets in a tabulation. Is there any reason not to set this per default?

it would break other things it's hard to predict what goes in cells so some heuristics works better when explicitly told Hans

while trying to create some interactive forms using latest beta (MkIV), I found that JavaScripts are only then copied into the PDF, if there’s a \goto referencing a JS function.

According to the old widgets manual I thought I could set default values of fields calling JS functions or variables as [JS(MyFunc)], but that doesn’t work. Greetlings Hraban,

This appears to be a pdf reader problem. On Win 8.1, Windows Reader and Chrome both show an editable field; Firefox and Sumatra show a non-editable field.

That’s not the problem, creating fields works great. Since JS works (probably) only in Adobe products anyway, I don’t care about other viewers.

But JavaScript code (within JSpreamble or JScode sections) is only copied by ConTeXt into the PDF if there’s a call of \goto to one of the defined JS functions. Additionally, calling JS functions for default values of fields doesn’t work like it did in MkII (and like it’s documented in m-widgets.pdf).

JS in PDFs is not easy to handle, but ConTeXt should at least copy my code into the PDF as it’s documented and used to work in MkII.
