doctrine2 - error `the name contains illegal characters`, in Doctrine 2 embeddable in Symfony 2,8 form -

doctrine 2 annotation embeddable not working in symfony 2.8 on windows.

@orm\embeddable not working, getting error : name "address.addr_line_1" contains illegal characters. names should start letter, digit or underscore , contain letters, digits, numbers, underscores ("_"), hyphens ("-") , colons (":"). error comes vendor...\src\symfony\component\form\formconfigbuilder.php .

seems reason dot in automatically generated name : "address.addr_line_1".

i tried disable automatic prefixes, , give own names. doctrine generates table columns names wrote : addr_line_1.

but generated form contain fields dot "address.addr_line_1", though error the name xxx contains illegal characters.

if use addr_line_1 in form, getting error, name not exists.

one of solutions put permission use dot in c:\bitnami\wampstack-5.6.20-0\apache2\htdocs\sym\learndb\vendor\symfony\symfony\src\symfony\component\form\formconfigbuilder.php.

return '' === $name || null === $name || preg_match('/^[a-za-z0-9_][a-za-z0-9_\.\-:]*$/d', $name);    

this works, new form generated, did not proceed futher yet, because need generate special getters , setters in embeddable. seems best solution use trait described here: http://russellscottwalker.blogspot.co.uk/2013/11/entities-vs-value-objects-and-doctrine-2.html

nevertheless, if knows how make embedable work, without changing symfony vendor code, please write.

maybe work direct queries select o order o o.address.addr_line_1 = : line1 http://welcometothebundle.com/persist-the-money-doctrine-value-object/ not work symfony form.

new versions of doctrine doesn't allow special characters underscores. have tried without them?

write variables, classes , folders in camel case considered practice also.
