Galleria.js Uncaught TypeError: Cannot read property 'left' of undefined on empty image list

[jlerbsc]

IMPORTANT

• If you open a issue, fill every item. Otherwise the issue might be closed as invalid.
• Before you open a issue, test it with the current/newest version.

1) Environment

• PrimeFaces version: 5.3
• Does it work on the newest PrimeFaces version? I don't know
• Application server + version: Tomcat8
• Affected browsers: Chrome 54.0

2) Expected behavior

No javascript error in JS console.

3) Actual behavior

When a galleria component contains no image, there is a Uncaught TypeError: Cannot read property 'left' of undefined
at c.select (/javax.faces.resource/galleria/galleria.js?ln=primefaces&v=5.3:1:3826)
at c.next (/javax.faces.resource/galleria/galleria.js?ln=primefaces&v=5.3:1:4580) in the navigator console
..

4) Steps to reproduce

Use showcase

5) Sample XHTML

..

6) Sample bean

Replace images list to empty list

@ManagedBean
public class ImagesView {

private List<String> images;

@PostConstruct
public void init() {
	//		this.images = new ArrayList<String>();
	//		for (int i = 1; i <= 2; i++) {
	//			this.images.add("nature" + i + ".jpg");
	//		}
	this.images = Collections.EMPTY_LIST;
}

public List<String> getImages() {
	return this.images;
}

}

Could you fix it in version 5.3 please?

[mertsincan]

I can add it into 5.3.x version. (Next version -> 5.3.18)

[jlerbsc]

Ok Thanks. Can i download it through maven repository?

[tandraschko]

Elite versions are not available via maven and you need to purchase elite access.

Too fast :) Thomas 👍

[jlerbsc]
