I have modify the sample demo code from http://www.zkoss.org/zkdemo/grid/paging from zul to zkjsp tag like this:
<z:page>
<z:panel id="mainP" framable="true" height="400px">
<z:panelchildren>
<z:grid id="grid" autopaging="true" mold="paging" vflex="true" pagingPosition="both">
<z:columns>
<z:column width="80px" label="Order #" align="left" />
<z:column label="Item Purchased" align="center" />
<z:column label="Purchased Time" align="center" />
<z:column width="80px" label="Paid" align="center" />
</z:columns>
<z:rows>
<z:zscript>
import org.zkoss.zul.*;
int[] orderArray = new int[26];
for (int j = 0; j < 26; j++) {
orderArray = 3456 + j;
}
</z:zscript>
<z:row forEach="${orderArray}">
<z:label value="${each}" />
<z:listbox mold="select">
<z:listitem label="Java" />
<z:listitem label="Latte" />
<z:listitem label="Lungo" />
<z:listitem label="Macchiato" />
<z:listitem label="Mocha" />
</z:listbox>
<z:timebox cols="12" format="a hh:mm:ss" onCreate="self.value = new Date()" mold="rounded" />
<z:checkbox label="No" onCheck='self.label= self.isChecked()?"Yes" : "No" ' />
</z:row>
</z:rows>
</z:grid>
</z:panelchildren>
</z:panel>
</z:page>
and there will be a exception:
org.zkoss.zk.ui.UiException: javax.servlet.jsp.JspException: javax.servlet.jsp.JspException: javax.servlet.jsp.JspException: javax.servlet.jsp.JspException: javax.servlet.jsp.JspException: javax.servlet.jsp.JspException: javax.servlet.jsp.JspException: javax.servlet.jsp.JspException: javax.servlet.jsp.JspException: javax.servlet.jsp.JspException: java.lang.NoSuchMethodException: org.zkoss.zul.Row: no method called forEach for at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:530) at org.zkoss.lang.Classes.newInstance(Classes.java:76) at org.zkoss.lang.Exceptions.wrap(Exceptions.java:162) at org.zkoss.zk.ui.UiException$Aide.wrap(UiException.java:44) at org.zkoss.jsp.zul.impl.RootTag$MyRichlet.service(RootTag.java:313) at org.zkoss.zk.ui.impl.UiEngineImpl.execNewPage0(UiEngineImpl.java:417) at org.zkoss.zk.ui.impl.UiEngineImpl.execNewPage(UiEngineImpl.java:302) at org.zkoss.jsp.zul.impl.RootTag.doTag(RootTag.java:273) at org.apache.jsp.WEB_002dINF.jsp.bom.bomAdmin_jsp._jspx_meth_z_page_0(org.apache.jsp.WEB_002dINF.jsp.bom.bomAdmin_jsp:199) at org.apache.jsp.WEB_002dINF.jsp.bom.bomAdmin_jsp._jspService(org.apache.jsp.WEB_002dINF.jsp.bom.bomAdmin_jsp:139) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:109) at javax.servlet.http.HttpServlet.service(HttpServlet.java:820) ......
is forEach can't work with zk jsp tag?
Hi jack,
Please using jstl with JSP
<c:forEach var="i" begin="1" end="3" step="1" varStatus="status">
<z:row forEach="${orderArray}">
<z:label value="${each}" />
<z:listbox mold="select">
<z:listitem label="Java" />
<z:listitem label="Latte" />
<z:listitem label="Lungo" />
<z:listitem label="Macchiato" />
<z:listitem label="Mocha" />
</z:listbox>
<z:timebox cols="12" format="a hh:mm:ss" onCreate="self.value = new Date()" mold="rounded" />
<z:checkbox label="No" onCheck='self.label= self.isChecked()?"Yes" : "No" ' />
</z:row>
</c:forEach>
thanks, but because of this problem: http://www.zkoss.org/forum/listComment/15427
<z:rows>
<z:zscript>
import org.zkoss.zul.*;
int[] orderArray = new int[26];
for (int j = 0; j < 26; j++) {
orderArray = 3456 + j;
}
</z:zscript>
<c:forEach var="num" items="${orderArray}" varStatus="status">
<z:row>
<z:label value="${num}" />
<z:listbox mold="select">
<z:listitem label="Java" />
<z:listitem label="Latte" />

<z:timebox cols="12" format="a hh:mm:ss" onCreate="self.value = new Date()" mold="rounded" />
<z:checkbox label="No" onCheck='self.label= self.isChecked()?"Yes" : "No" ' />
</z:row>
