contrib:Table - Help
Hi ,
I am trying to use contrib:Table instead of simple Foreach because for some special feature of contrib:Table.
I am following more or less same as LocaleSelect / LocalList example except that data is comming from DB.
The problem I am facing is, I am not able to bind correct object (InvoiceInfo) to Select link for each asn every row. I believe I have to do some job in "pageBeginRender" method, but I am not sure what I have to do. Just to avoid Null pointer Exception I am hard coding some value in Listener as shown below.
Could one you PLEASE,PLEASE help me as I am new to Tapestry / contrib:Table.
-------- .page BEGIN----------------------------
<component id="tableView" type="contrib:TableView">
<binding name="source" expression="invoiceList"/>
<binding name="columns">
'Invoice NO:invoiceNO, Product:product, Qty:quantity, '+
'!select'
</binding>
</component>
<component id="directSelect" type="DirectLink">
<binding name="listener" expression="listeners.selectInvoice"/>
<binding name="parameters" expression="selectInvoiceContext"/>
<binding name="row" expression="currentInvoice"/>
</component>
<property-specification name="currentInvoice" type="com.afx.invoice.domain.pojo.InvoiceInfo"/>
.
.
---------- .page END -----------------------------
------------.java BEDING ------------------------
public abstract class ListInvoice extends InvoiceBasePage implements PageRenderListener {
public List getInvoiceList() {
Visit visit = (Visit) getVisit();
int companyId = visit.getUser().getPk().getCompanyId();
return getInvoiceFacade().getInvoices(companyId);
}
//Listener
public void selectInvoice(IRequestCycle objCycle) {
Object[] arrParams = objCycle.getServiceParameters();
InvoiceInfo objInfo = new InvoiceInfo(new Integer(arrParams[3].toString()).intValue(),
new String("1"),
arrParams[0].toString(),
arrParams[2].toString(), 1);
}
public String[] getSelectFixtureContext() {
InvoiceInfo objInfo = getCurrentInvoicee();
return new String[]{
"InvoiceNo",
"Product",
String.valueOf(10)
};
public abstract VCFixtureInfo getCurrentFixture();
protected void finishLoad() {
getPage().addPageRenderListener(this);
}
public void pageBeginRender(PageEvent event) {
}
------------.java END -----------------------------
When the above code is executed the last coloumn "Select" will have always hard code value. Insted it should have correct values as in InvoiceInfo for that particular row.
Is my approach correct in Implementing Table component?
Your help is very much appreciated.
Regards
Hary.

Hi,
You do not need to do anything in pageBeginRender for what you describe, I
believe.
What probably causes you the problems is that the following binding
<binding name="row" expression="currentInvoice"/>
is in the directSelect component but should be in tableRows instead (or in
Table, if you use that instead of TableView). This is the parameter that
says where to store the currently rendered row, in your case the current
invoice.
I also assume that you have sth like this in your HTML:
<span jwcid="selectColumnValue@Block">
<a jwcid="directSelect">select</a>
</span>
This will define how the 'select' column will look. Without it, the column
will render the value obtained by calling getSelect() on the invoice.
Does this help?
