PanelBarRendererBase threw java.lang.StringIndexOutOfBoundsE

[tonylmai]

Hello,

I have a page built with rich:panelBar. While clicking around the rich:panelBarItem I ran into the following exception:

Caused by: java.lang.StringIndexOutOfBoundsException: String index out of range: 0

After the exception was thrown, I could not get back to that page until I restart the application.

I am using RichFaces 3.1.2GA with Seam 2.0.0GA and JBoss 4.2.1GA.

Thanks

could you provide a code snippet of how you use this rich:panelBar

[tonylmai]

it's been modified a little since I posted the exception. But basically it's like the following:

<rich:panelBar height="300">
 <c:forEach var='reportItem' items="#{clsSettleSRRptMgr.clrSettledRecords}">
 <rich:panelBarItem label="#{reportItem.tradable.tradableHoldingEntity.abbrevIntlName} (#{reportItem.tradable.exchange.exchangeAbbrevName} : #{reportItem.tradable.symbol})">
 <h:panelGrid columns="2" columnClasses="col-value,col-value">
 ...
 </h:panelGrid>
 <rich:separator height="1" lineType="dashed" width="50%" />
 <rich:spacer height="4" />
 <rich:dataTable rows="10000"
 onRowMouseOver="this.style.backgroundColor='#F1F1F1'"
 onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'"
 cellpadding="0" cellspacing="0"
 value="#{clsSettleSRRptMgr.getStockRecords(reportItem)}" var="record" >

 <f:facet name="header">
 <rich:columnGroup>
...

What happened I think was that when I cleared the result set, I accidentally left the flag to render the panel true and when panelBarItem tried to render with a null reportItem in

<rich:panelBarItem label="#{reportItem.tradable.tradableHoldingEntity.abbrevIntlName}

it was not happy.

After I reset the flag to not render the panel, the problem went away. What scares me is the inability to return to a page after an exception had been thrown without restart the application. Not sure if it's Seam's related issue or RichFaces.

Well, I thought this problem was solved but I was wrong. It popped up again. This time, I am not sure what the cause is.

Is it possible to at least check and prevent this IndexOutOfBound error within RichFaces?

Thanks

Can't reproduce the bug. Could you attach some example with reproducible code to Jira issue? My example:

<rich:panelBar height="300" id="cForEach" >
 <c:forEach var="time" items="#{toggleBean.items}" >
 <rich:panelBarItem label="#{time} Label" id="barItem#{time}" >
 <h:panelGrid columns="2" columnClasses="col-value,col-value" id="panelGrid#{time}">
 <h:outputText value="#{time}AAAAAAA" ></h:outputText>
 </h:panelGrid>
 </rich:panelBarItem>
 </c:forEach>
 </rich:panelBar>

Java bean:

private List<String> items = null;

 public Bean() {
 items = new ArrayList<String>();
 Random rand = new Random();
 for (int i = 0; i < 10; i++) {
 items.add(new Long(rand.nextLong()).toString());
 }
 }

public List<String> getItems() {
 return items;
 }

 public void setItems(List<String> items) {
 this.items = items;
 }
