formio/formio

Hello all, I use the formio-grid component. I noticed one bug: when you click on the column name, the table is sorted, then the other columns stop sorting. I looked at the source code of formio-grid on github. In the sort Column method of the FormioGridComponent class, the sort field assigns an empty value for columns other than the current one:
col.sort = ";
Although the 'switch' uses the undefined value. This means that this switch will never work for the other columns.
Is this a bug or did I get something wrong?

You can fix the bug by overriding the sortColumn function of the FormioGridComponent prototype:
FormioGridComponent.prototype.sortColumn = function(header: any) {
// Reset all other column sorts.
this.header.headers.forEach(col => {
if (col.key !== header.key) {
col.sort = undefined;
}
});

switch (header.sort) {
case 'asc':
header.sort = 'desc';
this.query.sort = '-' + header.key;
break;
case 'desc':
header.sort = undefined;
delete this.query.sort;
break;
case undefined:
header.sort = 'asc';
this.query.sort = header.key;
break;
}
this.refreshGrid();
}
