    [ https://jira.jboss.org/jira/browse/RF-3529?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12469827#action_12469827 ] 

Adam Michalik commented on RF-3529:
-----------------------------------

We came across this bug in production (not live demo).
The bug is reproducible always for certain images, using 3.3.0 and 3.3.1.
Behaviour:
- under Firefox everything works fine. The image is displayed on the web page. When we go into the page source code and go to the img src URL, the image appears
- under IE 7, the image is not displayed (an empty box with the red X appears as in the attachment). When we go to the img src URL, the following stack trace appears (RF 3.3.0.GA):

java.lang.NullPointerException
	org.richfaces.renderkit.html.Paint2DResource.isCacheable(Paint2DResource.java:81)
	org.ajax4jsf.resource.InternetResourceService.serviceResource(InternetResourceService.java:164)
	org.ajax4jsf.resource.InternetResourceService.serviceResource(InternetResourceService.java:141)

	org.jboss.seam.servlet.SeamFilter.doFilter(SeamFilter.java:158)
	org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)

Which in Paint2DResource points to:

	public boolean isCacheable(ResourceContext resourceContext) {
		ImageData data = (ImageData) restoreData(resourceContext);
		return data.cacheable; // Line 81 - data is null
	}
