Hi,
I have a grid style interface based on process backed record. One of the column(Documents) has multiple files. See the screenshot below:
I'm trying to display download link for the docs listed. I am getting error "Could not display interface. Please check definition and inputs.Interface Definition: Expression evaluation error at function a!forEach [line 358]: Error in a!forEach() expression during iteration 1: Expression evaluation error at function 'document' [line 361]: The passed parameter(s) are of the wrong type. Received the type List of Document."
Here is the code:
a!gridTextColumn( label: "Documents", field: "documentAttachmentArray", data: if(local!datasubset.totalCount=0,{},a!forEach(items: local!datasubset.data, expression: joinarray(index(fv!item, "documentAttachmentArray", {}),"; "))), links: a!forEach( items: local!datasubset.data, expression: joinarray(a!documentDownloadLink( label: document(index(fv!item, "documentAttachmentArray", {}),"name"), document: index(fv!item, "documentAttachmentArray", {}) ),"; ") ) )
Any help is appreciated.
Thanks,
Meena

Hi Meena,
If you are using 19.2 version or above, you can use below snippet,
136627,136626
{ a!sectionLayout( contents: { a!gridField( label: "Read-only Grid", labelPosition: "ABOVE", /* Any data with type data subset, cdt or dictornary can be used*/ data: { documentId: { 136627, 136626 } }, columns: { a!gridColumn( label: "Documents", value: a!richTextDisplayField( value: a!forEach( { 136627, 136626 }, { a!richTextItem( text: document( fv!item, "name" ) & char( 10 ), link: a!documentDownloadLink( document: fv!item ) ) } ) ) ) }, validations: {} ) } )}
----------------------------------------If your Appian version is less than that, then you can editable grid and use a!richtextdisplayfield and have all the rows read-only.
Thanks
