Not Getting proper list in custom list screenlet

[Prakash Kumar Singh, modificado hace 6 años.]

Liferay screen Version 2.0.1

Hi ,
I created custom list screenlet using 2.0.1 . Data is coming in proper form . But during populating data in list i have got some loading dots(....) as i move to down. And when i scroll up , data appeared before is not available there . i am attaching my NewsListView_default.swift code

 import UIKit
import LiferayScreens

public class NewsListView_default: BaseListTableView {
    // types of cell
    static let TYPE_HEADER = 0;
    static let TYPE_ITEM = 1;
    static let TYPE_LOADING = 2;
    static let TYPE_LOAD_COMPLETE = 3;
    static let TYPE_LOAD_FAILED = 4;
    static let TYPE_NEWS_ARTICLE = 5;
    static let TYPE_NO_INTERNET = 6;
    static let TYPE_NONE = 7;
    

    // register cell for nib
    public override func doRegisterCellNibs() {
        
        self.tableView?.registerNib(UINib(nibName: "NewsListHeader", bundle: nil), forCellReuseIdentifier: "mHeaderCell")
        self.tableView?.registerNib(UINib(nibName: "NewsListCell", bundle: nil), forCellReuseIdentifier: "mItemCell")
        self.tableView?.registerNib(UINib(nibName: "NewsListFooter", bundle: nil), forCellReuseIdentifier: "mFooterCell")
        self.tableView?.registerNib(UINib(nibName: "NewsArticleCell", bundle: nil), forCellReuseIdentifier: "mNewsArticleCell")
    }
    
    // override on show

Hi!
is this always happening? or only sometimes?
how many items do you have?

[Prakash Kumar Singh, modificado hace 6 años.]

1. First Behavior is when i scroll up list , list appeared before is not available there.
2. Second Behavior is when i scroll down list after 50 contents , some dots (.......) appears in place of content as shown in below image.

Hi!

I was reviewing your code and I have some suggestions:

- You should not override the behaviour of tableView(tableView: _ cellForRowAtIndexPath)
- If you want the row count use rowCount, not rows.count because rows is a map with the sections and their entries

Can you tried again applying this suggestions and let me if the error its still there?

Thanks!

Hi !
As you suggested i done . but problem is still exist.
and i checked that below code returning total number of rows .Is this behavior right ?

 
override public func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return rowsForSectionIndex(section).count
    }

Any Help ??

[Victor Galan, modificado hace 6 años.]

Sorry I thought that I'd answered you earlier

Can you send more code from the VC and the Screenlet class?

(for both forum threads)

Thanks

Thank you so much!

Let me check them, I'll try to reproduce it and let you know

[Prakash Kumar Singh, modificado hace 6 años.]

Any update ?

[Victor Galan, modificado hace 6 años.]

Hey

I've been unable to reproduce this, I think it has something to do with the Liferay service you're using. I've tried with almost 300 elements, tweaking the connectors but it is working fine.

Anyways there is a workaround possible, you have to add this line into your `NewsListPageLoadInteractor`:

open override func sectionForRowObject(_ object: AnyObject) -> String? {
		return " "
}

and in you `NewsListView_default`:

public func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
		return UIView(frame: CGRect.zero)
	}

This will change the view to only to not display the "..." instead of that It will show a loading in the bottom of the table while the next page it's being loaded.

If you can create a simple project that shows this strange behavior, we will fix it

Regards,

Víctor

Thanks @Victor

I will update you very soon . I wish these two tweakings will solve my problem.
