Dropdown filter + default



I'm having a weird behaviour and I don't know if I'm not setting my app properly or if it's a bug.


Here's the case:

- I have 3 objects : a gallery and 2 dropdowns representing a hierarchy (competencies and families of competencies)

- The competency dropdown if fed it's default value by the gallery and its item's collection is filtered by the value of the family dropdown



My problem is that it seems like the "default" value is fed before the items' filter is applied and then lost when the items collections is filtered. In other words :

- If I switch between selected gallery items within the same family (i.e.: "Power BI" and "SSAS Dev" both belong to the "tools" family), then the competency dropdown works just fine

- If however I switch from items belonging to different families (i.e.: "BO" to "Power BI"), then the default value sent by the gallery seems to be ignored/overwritten and the competency dropdown shows the first competency within the family selected. o_0


Is there a way to ensure the default is applied after the dropdown items collection has been filtered ? Or any other work around you can think about ?

Re: Dropdown filter + default

(relevant information)


The gallery

- Items : Uses a local collection with fields {Competency (string), CompetencyFamily (String), Maturity (String)}


The Family dropdown

- Items : Uses a local collection with fields {CompetencyFamily (String), IdCompetencyFamily (Int)}

- Default value : Gallery.Selected.CompetencyFamily


The Competency dropdown

- Uses a local collection with fields {Competency (String); IdCompetency (Int); IdCompetencyFamily (Int)}

- Items : Filter(CompetencyCollection ; IdCompetencyFamily = DropDownFamily.Selected.IdCompetencyFamily)

- Default value : Gallery.Selected.Competency


So long as I keep selecting items within the same family in the gallery, the behaviour works just fine. It's when I go between families that the issue occures.


If nothing else works, I'll probably hide the Family dropdown when I'm not in "new item" mode. It's only really a help to filter an otherwise pretty long Competency collection (200+ items).
