Safari中的空JSF graphicImage显示问号

Question

我有一些jsf代码，可以生成带有空图像的结果。在Windows中的Mozilla中执行相同的代码我只是没有图像。

这是实际生成此代码的代码：

<p:dataScroller id="timelineDatascroller"
                                value="#{searchController.commentModel}" var="comment"
                                scrollHeight="653" chunkSize="3" lazy="true">
                                <f:facet name="loader">
                                    <p:commandLink type="button" value="load more"
                                        icon="ui-icon-circle-triangle-s" />
                                </f:facet>
                                <p:panel>

                                        <h:outputText value="Age:" />
                                        <h:outputText value="#{comment.ownerProfile.age}" />
                                    </p:panelGrid>
                                </p:tooltip>
                            </p:dataScroller>

问题出在这个位置：

 <h:graphicImage rendered="#{comment.uploadedPhotoId ne null}"
                                        height="300" width="300"
                                        value="imageservlet?id=#{comment.uploadedPhotoId}" />
