I try to guess but I'm not sure at all.
Be++ ion is very little so in water it hydrolizes:
Be++ + 2H2O  ::equil:: Be(OH)2 + 2H+.
This reaction is displaced to the right if something can remove H+ ions, for example a basic species. Oxyacetate ions are basic. But it's probable that Be++ ions don't even form, dissolving the salt in water.
