Description of the problem:
I tried to resolve another problem involving editable textboxes in an online experiment on Pavlovia using the fix shown here, which requires calling a method on textbox._pixi. When I do so, I get this error (arith_calc_resp is the name of the textbox):
Unfortunately we encountered the following error:
- TypeError: arith_calc_resp._pixi is undefined
I logged the text box object to the console and I saw that the _pixi attribute was indeed undefined and also noted that _needPixiUpdate was “true”.
