Description
When bind variable produced by accumulate is used in the condition of subsequent accumulate like the following,
accumulate( Fact(id == $id, $str1 : str1);
$count : count($str1),
$maxStr1 : max($str1);
$count > 1
)
accumulate( Fact(id == $id, str1 == $maxStr1, $str2 : str2);
$maxStr2 : max($str2)
)
compilation fails with the error like the following (the error is a bit different per version).
