[jboss-user] [JBoss Seam] - Does injection perform standard JSF conversion?

[adambrod]

Hi-

I have a property in my managed bean that is injected from the request parameters.  Will Seam perform standard conversions like regular JSF managed properties?

This property fails: 
@In("#{param.managedFileId}")
  | protected Long managedFileId;

with the exception below.  From what I can tell, Seam is trying to inject the request parameter as a String, but the target expects a Long.  How can I fix this?  Here is the request url I'm using: http://localhost:8000/files/dFile.faces?managedFileId=30050
