VAO with DSA

Hello,
please have look on the following piece of code

`globjects::VertexArray::hintAttributeImplementation(globjects::VertexArray::AttributeImplementation::DirectStateAccessARB);`

`auto pVertexBuffer = globjects::Buffer::create();`
`pVertexBuffer->setStorage(vertices, gl::BufferStorageMask::GL_MAP_READ_BIT);`

`auto pIndexBuffer = globjects::Buffer::create();`
`pIndexBuffer->setStorage(indices, gl::BufferStorageMask::GL_MAP_READ_BIT);`

` //pVertexArray->bind();`
`auto pBinding1 = pVertexArray->binding(0); `
` pBinding1->setBuffer(pVertexBuffer.get(), 0, sizeof(v3v3));`
` pBinding1->setAttribute(0);`

When runing this code, I get the following error/debug message.
does not refer to an existing vertex array object.

If I call pVertexArray->bind(); before setting the buffer and attributes format, everyhting is fine so far. But VAO with use of DSA usually do not need to bind before setting the buffer or attributes format. Is this by design ?

In plain OpenGL this would be something like this here

`glCreateBuffers(1, &vboId); `
`glCreateBuffers(1, &iboId); `
`glCreateVertexArrays(1, &vaoId);`

`glNamedBufferStorage(vboId, vertices.size() * sizeof(v3v3), vertices.data(), GL_MAP_READ_BIT);`
`glNamedBufferStorage(iboId, indices.size() * sizeof(uint32_t), indices.data(), GL_MAP_READ_BIT); `

`glVertexArrayVertexBuffer(vaoId, 0, vboId, 0, sizeof(v3v3));`
`glVertexArrayElementBuffer(vaoId, iboId);`

`glEnableVertexArrayAttrib(vaoId, 0); `
`glVertexArrayAttribFormat(vaoId, 0, 3, GL_FLOAT, GL_FALSE, 0); `
`glVertexArrayAttribBinding(vaoId, 0, 0); `

`glEnableVertexArrayAttrib(vaoId, 1);`
`glVertexArrayAttribFormat(vaoId, 1, 3, GL_FLOAT, GL_FALSE, offsetof(v3v3, color));`
`glVertexArrayAttribBinding(vaoId, 1, 0);`

kind regards,
