Debug Logs
oh I should add before I forget we are using the latest managed base components (2.17) and unmanaged screen (2.2.1)
I tried but was not able to reproduce this problem. Exactly what kind of inputs are you providing to the component?
just a couple of string collections the first contains labels of countries the second contains the Object ID of the country
I can confirm this is still an issue in the Winter '22 release.
FlowActionsBasePack - 2.33 FlowScreenComponentsBasePack - 2.5.9
I created a very basic screen flow to test this component out. I have two string collection variables. One (SourceLabelsCollection) stores the labels (which do contain spaces) for the dual list box and the other (SourceValuesCollection) stores the values (no spaces). I have an assignment element that populates both collection variables and I have a screen component with a single Dual List Box component. The DLB component is configured as follows:
Select datasource: Two string collections All Options > Labels: SourceLabelsCollection All Options > Values: SourceValuesCollection
When I run this flow in debug mode, the component seems to function just fine. I see the labels with spaces in them on the left side and I can select various choices without issue. Once I click the Finish button (or next to another screen), then I receive this error:
"The Lightning Component c:fsc_dualListBox2 generated invalid output for field selectedOptionsFieldDescriptorList. Contact your administrator with these details: Flow encountered an error when processing and converting between data types. Please check the flow and ensure all data types are matched correctly."
