Issue when more than 1 character in dropdown

[jhen1115]

Hi,

There is a dropdown validator issue when more than 1 character in dropdown. For example,

rhandsontable(data.frame(char = rep("Ab", 2))) %>%
   hot_col(
      "char",
      type = "dropdown",
      source = "Ab"
)

The background of cells will be changed to red after the dropdown is opened.

However, if the "Ab" is changed to "A", then the background of cells will not be changed after the dropdown is opened.

Now, the below validator argument is added to resolve the issue

validator = paste0(
   "function(value, callback) {",
   "   callback(value === 'Ab' ? true : false);",
   "}"
)

..., however, does anyone have better resolution for solving this issue?

Thank you
