Hi all,  
first thread here, loving weweb so far.

i’m building a simple marketplace with filterable listing, i’m working with some Input multiselect. i made a component and so far with user input they work perfectly.  
Now i’m trying to assign the currentSelection value programmatically (i need to read it from the query string)  
I tried set the Initial value but this doesn’t trigger the onChange workflow that changes the filters and update the filtered collection.

I created a Set Value Action on the Input Multiselect component. It set the currentSelection to update the UI of the multiselect and then triggers the onChange event. When i run this workflow with the test values, the variable is changed and the event is triggered in the log…but not really: the component’s instance that has a workflow on the onChange event doesn’t seem to do anything, the actions in “Filter by Providers” don’t happen (it just set a filtering variable and fetch a collection with the new filter).

**Actions and triggers within the Input multiselect component “Filter DD”:**

**Set Value workflow:**

**OnChange on the instance of the component**

Similar thing with a page workflow “on page load before fetching collection”:  
i set the parameter that is used to filter the collection (i read it from queryparam). the collection is then not filtered. if i switch the workflow to just “on page load” and add the a “fetch collection” action, then all is good.

am i missing something about these workflows? or probably some error on my side or bug…

thanks to anyone that will clarify these. great community!

i suspect the first problem occurs only with the “test” button, not if i invoke the Set Value from a button or another workflow

Hi @vfede 👋

I think this is normal JS behavior. Can you please try to handle this in the page’s initialization workflow and let me know if it works?

Create a workflow on page load in which you:

- Get query parameter
- Set value (for multiselect)
- Update variable (for filter state)
- Fetch collection
