Using 18 digit Id is not giving me correct href link.

Can someone give me Idea to place directly 15 digit Id in visual force outputlink syntext with loop.

I don't want to go to controller nad come back with Id.

-any way to get 15 digit Id from query instead of 18 digit.

-Thanks

I have a table on a Visualforce page where the first two columns have buttons that can edit or delete the corresponding rows. Both buttons use essentially the same code and call very similar APEX code. However, one works, and the other does not:

 Works:

VISUALFORCE

<td>

<apex:commandbutton action="{!edit}" value="Edit" rerender="itemList">

<apex:param name="editid" value="{!rowitem.Id}"/>

</apex:commandbutton>

</td>

APEX CODE

public PageReference edit() {

String editid = getParam('editid');

editItem = [SELECT id, Name,Total_Price__c,Quantity__c, Description__c,Agreed_Carriage__c,Agreed_Price__c,Reference__c,Purchase_Order__c FROM SFDC_Purchase_Requisition__c WHERE Id=:editid];

return null;

}

 DOESN'T WORK

VISUALFORCE

<td>

<apex:commandbutton action="{!del}" value="Del">

<apex:param name="delid" value="{!rowitem.Id}"/>

</apex:commandbutton>

</td>

APEX CODE

public PageReference del() {

try {

String delid = getParam('delid');

SFDC_Purchase_Requisition__c item = [SELECT Id FROM SFDC_Purchase_Requisition__c WHERE Id=:delid];

delete item;

} catch (Exception e) {

ApexPages.addMessages(e);

}

return null;

}

 The error I get is a standard "List has no rows for assignment to SObject", due to the fact that it seems to think that "delid" is a null string.

I have added debug logs to each instance of Apex that output the current page. In the sample that works, the parameter "editid "can be seen and is correctly formed within the url of the current page.

Oddly, when debugging the code that doesn't work, it seems that the parameter isn't correctly passed into the url. I was able to find the {!rowitem.id} but it isn't linked to the name "delid". Instead it seems to be linked to what must be a Salesforce code name which looks something like:

j_id0%3Aj_id28%3Aj_id44%3Aj_id46%3A0%3Aj_id66=a0qR0000000JBkNIAW // a0qR0000000JBkNIAW is the rowitem id

I've also put in other test parameters and found a similar occurance. 

The table is formed from nested  <tr> and <td> tags and in all other ways performs as expected. I was just wondering if anybody knew of a reason behind this?

We've got a list button that calls a VF pg which uses an extension to the standard controller for a custom object.

Unless I'm absolutely crazy, this worked fine very recently.  (Last week?)  Today it doesn't work.  I get the following error:

Invalid variant 'parent': value 'Opportunity'

Which I don't understand at all.  I've tried it in various instances and it seems to have stopped working everywhere.  SF, did you push a change that caused this to stop working?

Here's the code.  First the page:

<apex:page standardController="OppPayment__c" recordSetVar="installments" extensions="ONEN_EXT_MarkPaymentsPaid" action="{!markInstallmentsWrittenOff}">
<apex:param name="mark" value="writeoff"/>
</apex:page>

next the extension:

public class ONEN_EXT_MarkPaymentsPaid {

private List<OppPayment__c> selectedInstallments;
private String mark;

//have to instantiate with StandardSetController for list buttons
public ONEN_EXT_MarkPaymentsPaid(ApexPages.StandardSetController controller) {
//get the selected ids that were checked
this.selectedInstallments = (List<OppPayment__c>)controller.getSelected();
}

public pageReference markInstallmentsPaid() {
mark='paid';
PageReference p = markInstallments();
return p;
}

public pageReference markInstallmentsWrittenOff() {
mark='writeoff';
PageReference p = markInstallments();
return p;
}

pageReference markInstallments() {
//get all the installments that were selected
List<OppPayment__c> InstallmentsFromSelection = [select Id,paid__c from OppPayment__c where Id IN :selectedInstallments];
if (InstallmentsFromSelection.size()>0) {
for (OppPayment__c thisInstallment : InstallmentsFromSelection) {
//if we're passing in paid on the querystring, mark them paid
if(mark=='paid') {
thisInstallment.paid__c=true;
thisInstallment.Written_Off__c=false;
} else if(mark=='writeoff') {
thisInstallment.Written_Off__c=true;
thisInstallment.paid__c=false;
}
}

update InstallmentsFromSelection;
}
PageReference p = new PageReference(System.currentPageReference().getParameters().get('retURL'));
p.setRedirect(true);
return p;
}
}

 BTW, OppPayment__c is a custom object which is detail-master to Opportunity.  The button is being accessed from a related list on an Opportunity layout.

edit: I just discovered that this list button works fine when called from the Console or from an OppPayment__c list view.  So the error seems to only occur when it's called from a related list on the Opp layout.  (Hence the reference to Opportunity being the 'parent', I assume.)

BTW, we have unit tests, and they all still pass.  So whatever the issue here is, it seems to happen only in the SF UI.   Also, nothing shows up in the System Log.

Can anyone help here?  

Thanks much!

Tag Library supports namespace: http://salesforce.com/standard/components/apex, but no tag was defined for name: form

Any help would be great...
