Why does this JSF expression not work?

Question

I have a simple problem on .xhtml page. This expression is not working :-

<a href="Photos.jsf?albumId=#{item.albumId}&blogId=#{PhotoAlbumsCommonBean.blogId}">
 photos
</a>

I get this error :-

Error Parsing /Common/PhotoAlbums.xhtml: Error Traced[line: 20] The reference to entity "blogId" must end with the ';' delimiter.

And this is causing some kind of error.

I was making the same mistake, but puzzling over my '&&' logical operator in javascript. – Erring

Answer 1

Try to encode the ampersand - & with &

An

It doesn't work :(. Now the error is :-The reference to entity "ampblogId" must end with the ';' delimiter. – Latoya

Have you put the semicolon after the &amp? – An

Replace it with "&" and it will work. The URL should be Photos.jsf?albumId=#{item.albumId}&blogId=#{PhotoAlbumsCommonBean.blogId} – Hoosegow

@Petar - you can use the backtick character to escape code in the Markdown editor – Malefactor

using & (an xhtml code for ampersand character) is a safer option, i reckon! – Dissertation

Answer 2

The error is caused by the # signs.

Try this. It fixes the problem with the JSP EL and having ampersands encoded in XHTML pages:

<a href="Photos.jsf?albumId=${item.albumId}&amp;blogId=${PhotoAlbumsCommonBean.blogId}">
 photos
</a>

@Nitesh What do you mean it disappears? Does the querystring just look like this: "?albumId=&blogId=..."? – Wolters

Hi Steven, your answer is also correct. Don't know which one to vote as correct and give points :p. But i think, $ is not meant for JSF. It is for JSP, though it works. – Latoya

I guess the correct symbol to use depends if you want immediate or delayed variable expansion. Good point. – Wolters
