Oracle JET (JavaScript Extension Toolkit) is a powerful framework for building modern web applications. The oj-list-view component, a part of Oracle JET, provides a flexible and customizable way to display lists of data. While working with oj-list-view in your Oracle JET application, you might encounter some challenges and errors. In this blog, we’ll explore common issues developers face and provide insights on how to address them.
Layout and Styling Issues:
Problem: Inconsistent or incorrect styling can result in a poorly rendered or misaligned oj-list-view.
Because of the above code the cards did not render properly and even each card dimensions are also different like described in the images below.
Solution: So, to improve the layout HTML code is modified i.e., We added a display attribute as shown below.
Verify the class and style bindings, paying attention to classes like oj-listview-item-padding-off and oj-sm-padding-2x-bottom. Make sure they are applied appropriately based on your layout needs.
The layout or the cards after improving the HTML code is much more organised and appealing to view.
Data Binding Issues:
Problem: One common mistake is incorrect data binding, leading to an empty or improperly displayed list or no list at all.
In the above code, the value assigned to data attribute is based on a condition i.e., if scrollValue is true, then value assigned to the data attribute is listDataProvider1 otherwise it is listDataProvider. But it should be vice-versa. So, because of that we are not getting any data in my page as shown in the figure below.
Solution:
Ensure that the data attribute (data=”[[yourDataProvider]]”) is correctly bound to your data provider. So, after correcting the above mistake, the cards are coming properly as you can see in the images below:
Check the data structure and make sure it matches the expected format
CONCLUSION:
Working with the oj-list-view component in Oracle JET can be a smooth experience when potential complications are understood and addressed. By paying attention to data binding, styling, and other common issues, we can build robust and user-friendly applications using Oracle JET.
