I use bokeh. and I want to change ColumnsDataSoruce in Custom JS when user push checkbox. But I write ““src_x = source_t”” in Custom JS. I met a error " Models must be owned by only a single document" . I want to solve this problem. Someone helps to me?
And I mention that I delete ““src_x = source_t”” in Custom JS, I hadn’t met error. But I need this ColmunsDataSource.
