setFilter() of Dataset causes timeouts or connection errors

Hi There,

does anyone have an idea why while changing filters and refreshing a dataset sometimes creates timeouts or even connection refuses? Se screenshot below…

I have a multi-language page where I let the user change the language of descriptions that are linked and marked with a language code from a database. Seldom it works immediately… mostlz it takes 10-30 seconds to change the filter and sometimes it fails as the connection is refused or there is a timeout. Anyone else experiencing this behaviour? Does anyone have a solution?

A short video showing the problem here… I really don’t know why these problems occure… Anyone any ideas? Thanks!
