oh yes sorry : below are the error trace and the minified js line 9 with this “a is null” error.
According to my check of this js line : the 8508 position in this line does correspond to the “a.field_get_client(…)” in this chunk of js code :
…
this.prm.done(
function(){
if(void 0===b)return this.screen.new_group(),
this.screen.set_current_record(null),
this.screen.group.parent=null,
void this.screen.display();
var c=a.field_get_client(this.field_name);
c!=this.screen.group&&(this.screen.set_group©,“tree”==this.screen.current_view.view_type&&this.screen.current_view.editable&&this.screen.set_current_record(null));
var d=,e=null;
a&&(d=b.get_domain(a),e=a.expr_eval(this.attributes.size)),
this._readonly&&(e=null===e?this.screen.group.length:Math.min(e,this.screen.group.length)),
Sao.common.compare(this.screen.domain,d)||(this.screen.domain=d),
this.screen.size_limit=e,
this.screen.attributes.readonly=this._readonly,this.screen.display()
}.bind(this))},
