Probelms With JSF dataTable and Milionic Menus
Hi
I am using JSF Data table and the milionic menus. When i right click on any row i am getting update and delete menu options. When
i am clicking on the delete i am getting the below exception. and i have written the setter and getter methods for selectedRowId.
My dataTable and meus codes are like below
<h:dataTable value="#{SolutionMgmt.solutions}"
var="soln"
border="1" cellspacing="0" cellpadding="2"
width="640"
onmouseup="WestContextMenu.popup('solnmgmtpopupMenu')">
<h:column>
<f:facet name="header">
<f:verbatim><b>Code</b></f:verbatim>
</f:facet>
<f:verbatim>
<span class="spanRowId">
<h:outputText value="#{soln.errorCodes}"/>
</span>
</f:verbatim>
</h:column>
<h:column>
<f:facet name="header">
<f:verbatim><b>Solution Name</b></f:verbatim>
</f:facet>
<h:outputText value="#{soln.solutionName}"/>
</h:column>
<h:column>
<f:facet name="header">
<f:verbatim><b>Description</b></f:verbatim>
</f:facet>
<h:outputText value="#{soln.description}"/>
</h:column>
</h:dataTable>
<h:commandButton id="addnewsolution" type="submit" value = "#{msg.newsolution}" immediate="false">
</h:commandButton>
<%-- The milonic menu component --%>
<h:inputHidden value="#{SolutionMgmt.selectedRowId}" id="selectedRowUuid" />
<m:menu id="solnmgmtpopupMenu" onselect="WestContextMenu.setSelectedRowId('SolutionMgmt')" contextmenu="true">
<m:menuitem value="Update" />
<m:menuitem value="Delete" action="#{SolutionMgmt.deleteSolution}"/>
</m:menu>
i am using the below java script functions to set the value.
I am getting spans[i].childNodes[0].nodeValue nothing for this. So values are not being set.
/**
* Extracts the id of the row that the user has selected.
*/
this.setSelectedElementId = function(selectedRow) {
alert ("selectedRow = " + selectedRow);
var spans = selectedRow.getElementsByTagName("SPAN")
for (i = 0; i < spans.length; i++) {
if( spans[i].className == "spanRowId") {
alert("NODE VALUE = " + spans[i].childNodes[0].nodeValue);
this.selectedElementId = spans[i].childNodes[0].nodeValue;
alert ("selectedElementId = " + this.selectedElementId);
}
}
}
this.popup = function(contextMenuName) {
// If its not a context menu do not popup
if(!this.isWestContextMenu(contextMenuName)) {
return;
}
ev=event.button;
// detect right click and process the popup
if(ev==2||ev==3){
document.oncontextmenu = new Function("return false");
this.selectedElementId = null;
var selected = this.getContextRow(window.event.srcElement);
if(selected != null) {
this.setSelectedElementId(selected);
}
//this.setCallingElement(selected);
if(this.selectedElementId != null) {
this.doPopup(contextMenuName);
}
}
