I've got a strange error. I grabbed the controller code from this blog post, but when I try to save it to my dev org, I get an error: unexpected token: '='. I can't seem to figure out why. Any help would be appreciated!

Here's the controller throwing the error:

Public class ThumnailController {

  public String imageUrl {get; set;}

  ContentVersion[] cvs = [select id from contentversion where contentdocumentid= '0691a0000015c3v' and isLatest=true];

  imageUrl ='/sfc/servlet.shepherd/version/renditionDownload?rendition=THUMB720BY480&versionId=' + cvs[0].id;

}

The error is being thrown at this line:

imageUrl ='/sfc/servlet.shepherd/version/renditionDownload?rendition=THUMB720BY480&versionId=' + cvs[0].id;

 

I'm getting this error on Wave Desktop Exploration: Analyze Your Data Over Time.
I've redone the lens several times and checked that I am evaluating on the correct Dev Org.

Any help?

hello Team,

 Is there a way to regulate access to this method? Like a permission in a profile or permission set? Or only give a specific user access to this method? 

Thanks
