Hi, 

the right code is:

 <xpath  expr="//page[@name=''order_lines]//tree/field[@name='name']" position="attributes">   

   <attribute name="invisible">1</attribute>  

<xpath>

who ever is facing this issue and couldn't solve:

First go to your xml file and inherit the view form:

then in the arch field use the xpath as below:

            1        

Now good to go.
good luck.

Hi,

This is happening due to the 'section_and_note_one2many'  and 'section_and_note_text' widgets. In the code they are displaying section and notes in the place of field 'name'.

You can achieve this by extend  SectionAndNoteListRenderer with following code:

_renderBodyCell: function (record, node, index, options) {
    var $cell = this._super.apply(this, arguments);
    if (node.attrs.name === "name" && record.model === 'sale.order.line'){
        return $cell.addClass('o_hidden');
    }
    return $cell;
},
_getNumberOfCols: function () {
    var n = this._super();
    if(this.state.model === 'sale.order.line'){
        n--;
    }
    return n;
},

_renderHeaderCell: function (node) {
    if (node.attrs.name === "name" && this.state.model === 'sale.order.line'){
        return;
    }
    else{
        var $th = this._super.apply(this, arguments);
        return $th;
    }
}

​

 Thanks
