SingleSelect and MultiSelect Editors not working correctly when sorted desc about aurelia-slickgrid HOT 7 CLOSED

@jmzagorski
I found the issue in the Editor because of the use of the find and indexOf here to pre-select the default value. If we sort the collection descending, and we have a cell value of 94, the find will return 2 found items 9 and 4 and since the last found value is 4, it will select that one.

You can already see this bug on the live Example 3 demo on the "% complete" column because that one has the sorted collection in descending order.

yup, can't remember why I used indexOf. I think because the multiSelect returned an array and I just copied a lot of the logic over to singelSelect without testing it good enough? I'll have to look at it

I actually found that problem while doing the new feature of Excel Copy Buffer, which I just merged. This copy buffer uses the serializeValue function to copy each cell values into it's buffer when the column definition is an editable field (Example 3). So anyway, I believe the MultipleSelectEditor also has this problem since it also uses the indexOf.

I tried it in my Angular repo and made these changes

-      if (this.defaultValue.indexOf($e.value) !== -1) {
+      if (this.defaultValue === $e.value) {

That seems to be all good, also note that this.defaultValue is of type string because the previous line adds a cast with toString().

You can do the change today or I'll make the change sometime tonight.

That will work for the singleSelectEditor, but not the multipleSelectEditor. The multipleSelectEditor.defaultValue is an array so you need to make that indexOf check to see if the select value exists in the array. I believe this was a copy and paste error on my part from the multipleSelectEditor to the singleSelectEditor.

Side note, i was put on a high priority 1 week project since the end of last week so I have not been able to get to anything I wanted to on slickgrid.

There was 2 indexOf in the MultipleSelectEditor and I changed one of them with the same modification as the SingleSelect. I think you were possibly thinking about the 1st indexOf, which I didn't change. Anyhow, I made the same change in both Editors and tested with Example 3 with the collection sorted descending and they both work as expected (I'm actually not sure if it affected the MultipleSelect at all, anyhow I changed it too).

We can re-open if it comes back, but it seems to be ok with the quick tests I made, so I'll close the issue.

I just released last version 1.12.0 before vacations, this fix is included in it :)

A lot of goodies before I leave.
