java - 在 Primefaces 中使用 Galleria 进行 imageRotateAndResize

Question

我正在使用带有 StreamedContent 的 Galleria 来显示来自 c:// 的图像。画廊正确显示图像，但是当我使用按钮使用 pe:imageRotateAndResize 缩放图像时，它只影响第一张图像，当我更改图像并使用按钮时，它仍然只影响画廊中的第一张图像. 我需要什么或必须纠正什么，以便 pe:imageRotateAndResize 影响画廊的当前形象，而不仅仅是第一个？Primefaces 和 PrimefacesExtensions 版本 6.0-6.0.0

xhtml代码：

    <p:galleria id="galleriaC" var="galle" value="#{controller.imagenes}"  autoPlay="false" showCaption="false"
                                    style="width: 100%; max-width: 100px; min-width: 100%; min-height: 10px; height: auto; overflow:scroll; ">
                            <p:graphicImage id="myImage" value="#{controller.imageItem}" style="width: auto; height: 100%;">
                                    <f:param name="gh" value="#{galle}"/>
