Force refresh in recursive list

Ask the community

Hi guys. I am building a folder structure view based on “folder” records and child/parent relations. We have a runtime property on the “folder” record, that decides if the subfolders should be shown or not. I have created a recursive JS function to figure out if any parents are closed. My problem is that I need something to trigger a refresh in order to recalculate when the runtime property is changed.
Or am I totally overthinking the problem?
Any feedback is appreciated :slight_smile:

Hi again guys. Found a solution in the meantime. Here is how I solved it:
I added a runtime property to the datasource, containing a javascript function which recursively iterates through all parent object in search of any that are not expanded. Here is the code for the runtime property:

let returnValue = true;
findParentClosedFolders(CurrentID);
return returnValue;

function isNotNothing(value) {
return value !== undefined && value !== null;
}

function findParentClosedFolders(folderID) {
// Find the folder by ID
const currentFolder = dRFolderAllInTenant.find(folder => folder._id === folderID);

if (currentFolder && isNotNothing(currentFolder.parent)) {
    // Find the parent folder
    const parentFolder = dRFolderAllInTenant.find(folder => folder._id === currentFolder.parent);

    if (parentFolder) {
        if (!parentFolder.expanded) {
            // The parent exists and is not expanded. Set returnValue to true.
            returnValue = false; //true;
        } else {
            // The parent exists and is expanded. Check its parent recursively.
            findParentClosedFolders(parentFolder._id);
        }
    }
}

}

Great to hear that you found a solution to your problem, but have you checked out the tree / recursive mode on the Iterating Container.

It might fit your needs

Hi Erik and thank you for your reply. Yes that’s the one I’ve been using :slight_smile:
