Common Kony (Temenos Quantum) Issues and Solutions

1. Build Failures in Kony Visualizer

Projects fail to build, preventing successful app deployment.

Root Causes:

Incorrect SDK configuration or missing dependencies.
Conflicts between Kony Visualizer and native SDKs.
Unsupported third-party plugins causing build errors.

Solution:

Ensure required SDKs and dependencies are installed:

Check project settings and verify Android/iOS SDK paths.

Clean the project before rebuilding:

Project > Clean > Build All

Review logs for detailed error messages:

View > Logs > Build Output

2. Performance Issues and Slow UI Rendering

Applications run slowly or experience UI lag during navigation.

Root Causes:

Heavy use of animations and UI transitions.
Excessive JavaScript event handlers causing delays.
Unoptimized API calls leading to blocking operations.

Solution:

Optimize UI elements by reducing animations:

Disable animations for non-essential UI updates.

Use asynchronous API calls to prevent UI blocking:

kony.net.invokeServiceAsync(url, params, callback);

Optimize event listeners to minimize performance overhead:

Remove unused event handlers and optimize DOM updates.

3. Authentication and Login Failures

Users are unable to log in due to authentication errors.

Root Causes:

Incorrect identity service configuration.
OAuth tokens not being generated or validated properly.
Server response format mismatch.

Solution:

Verify identity service configurations in Kony Fabric:

Check OAuth settings and authentication endpoints.

Ensure correct API response handling:

if (response.opstatus === 0) {  console.log("Authentication successful");} else {  console.log("Authentication failed", response);}

Debug authentication logs in the server console:

View > Logs > Authentication Debug

4. API Integration Issues

External APIs fail to connect or return incorrect data.

Root Causes:

Incorrect endpoint URLs or API keys.
Cross-origin request blocking (CORS) issues.
Invalid JSON response format.

Solution:

Verify API endpoints and keys:

Ensure API URLs and authentication tokens are correct.

Enable CORS on the server for external API calls:

Access-Control-Allow-Origin: *

Validate JSON response format before processing:

try {  var data = JSON.parse(response);} catch (e) {  console.log("Invalid JSON response", e);}

5. UI Layout and Rendering Issues

UI elements do not render correctly or display inconsistently across devices.

Root Causes:

Incorrect flex container properties affecting layout.
Device-specific rendering inconsistencies.
Outdated Kony runtime affecting UI behavior.

Solution:

Ensure proper flex properties are set for UI components:

form1.flexContainer.layoutType = kony.flex.FLOW_VERTICAL;

Test layouts across different screen sizes:

Use Kony Visualizer’s responsive design mode.

Update Kony runtime to the latest version:

Update runtime libraries in project settings.

Best Practices for Kony (Temenos Quantum) Development

Regularly update SDKs and Kony Fabric components.
Use asynchronous API calls to prevent UI blocking.
Optimize flex layouts for consistent cross-platform UI rendering.
Test applications on multiple devices before production deployment.
Monitor logs to diagnose authentication and API issues early.

Conclusion

By troubleshooting build failures, performance bottlenecks, authentication issues, API integration problems, and UI rendering inconsistencies, developers can ensure smooth development using Kony (Temenos Quantum). Implementing best practices improves app stability and enhances user experience.
