在Primefaces中使用Galleria进行imageRotateAndResize

如何解决在Primefaces中使用Galleria进行imageRotateAndResize

我正在将galleria与StreamedContent一起使用，以显示来自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，它仅影响第一个图像，而当我更改图像并使用按钮时，它仍然仅影响图库中的第一个图像。 我需要什么或必须纠正什么，以便pe：imageRotateAndResize会影响当前图库的图像，而不仅仅是第一个？ Primefaces和PrimefacesExtensions版本6.0-6.0.0

xhtml的代码：

    <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}"/>
                            </p:graphicImage>
                        </p:galleria>
    
                      
                        
                        <pe:imageAreaSelect id="areaSelect"
                                            for="myImage"
                                            widgetvar="areaSelectWidget"
                                            autoHide="true"
                                            handles="false"
                                            movable="false"
                                            persistent="false"
                                            resizable="false"
                                            >
                            <p:ajax event="selectEnd" listener="#{controller.selectEndListener}" update="msg"/>
                        </pe:imageAreaSelect>
    
    
                        <pe:imageRotateAndResize id="rotateAndResize" for="myImage" widgetvar="rotateAndResizeWidget" >
                            <p:ajax event="rotate" listener="#{controller.rotateListener}"
                                    update="msg" oncomplete="PF('areaSelectWidget').reload();"/>
                            <p:ajax event="resize" oncomplete="PF('areaSelectWidget').reload();" />
                        </pe:imageRotateAndResize>
    
                        <p:commandButton value="Regresar" actionListener="#{controller.regresar()}" update=":form"/>                
                        <p:commandButton icon="ui-icon-zoomin" value="Scale +"
                                         onclick="PF('rotateAndResizeWidget').scale(1.05);return false;"/>
                        <p:commandButton icon="ui-icon-zoomout" value="Scale -"
                                         onclick="PF('rotateAndResizeWidget').scale(0.95);return false;"/>

            return imagenes;
