s:graphicImage input == null!

[umajeric]

Did anyone have a problem with s:graphicImage?
I have a problem when I put in value path to my picture:

<s:graphicImage value="/pictures/#{user.picturePath}" />

if there is no picture in this path it says

input == null!

Thanks,
Uros

[umajeric]

Anyone?

[keithnaas]

Uros,

What is the "it" in this statement, "if there is no picture in this path it says input == null!"?

A stack trace?  The rendered image tag?  A log file message?

Sorry, I wasn't specific enough:

Stack trace is:

java.lang.IllegalArgumentException: input == null!

You want h:graphicImage, not s:graphicImage.

[keithnaas]

Also, if you don't want to render the picture when its not in the path, use the rendered attribute. 

Cheers

[umajeric]

You want h:graphicImage, not s:graphicImage.

In this case I can not use

<s:transformImageSize width="xxx" />

Also, if you don't want to render the picture when its not in the path, use the rendered attribute.

How to test if path exists with EL?

[christian.bauer]

You can not use s:graphicImage to transform arbitrary files loaded from your filesystem (unless you provide a java.io.File handle through a backing bean). You can however load and transform them from the classpath as a resource.

[umajeric]

But it works if I give a path to picture and transformImageSize. Picture size is actualy xxx px wide.
