Hi,
There is a requirement in my project to add and delete a row onclick of a button.
Each row has a drop down which displays ("<",">","<=",">=") operators.

When i am using the below HTML code for displaying dropdowns ,add and delete functionalities working fine..
<select name="select13" class="TextBlackNormal">
<option>></option>
<option><</option>
<option>>=</option>
<option><=</option>
</select>

But in case of JSF dropdown tag,add and delete fucntionalites are not working onclick of a button.But it displays the dropdown List.

<h:selectOneMenu value="#{ruleBlock.priceRangeFromOperator}">
<f:selectItems value="#{PriceVarianceRuleBean.priceRangeOpeList}"/>
</h:selectOneMenu>


I configured the priceRangeOpeList as
priceRangeOpeList.add(new SelectItem("<","<","<"));
priceRangeOpeList.add(new SelectItem(">",">",">"));

Add and delete functionlaites are working fine if i use below configuration for the drop down.but the the values in the drop down are dispalyed as (>,< like this instead of < , >).So i think the problem is with the operators.Can you please tell me how to display these opearators in the dropdown.
priceRangeOpeList=new ArrayList();
priceRangeOpeList.add(new SelectItem(">",">",">"));
priceRangeOpeList.add(new SelectItem("<","<",">"));

hi ,

I am using JSF checkbox inside a dataTable.I am calling a javascript function by passing the argument (this object).
The value of the checkbox returns true when checkbox is unchecked.Why is the value always true?
What should be done to get the value as false when the checkbox is unchecked.Can anyone help me?
Please find my code below.



<h:dataTable cellspacing="0" cellpadding="3" width="100%" border="0" value="#{MSPSSecurityProfileDetailsBean.mspsDataModel}" var="item" rowClasses="oddRow, evenRow" headerClass="gridContainer" style="border-bottom:none;">
<h:column styleClass="Header">
<f:facet name="header" width="1%">
<h:outputText value="" />
</f:facet>
<h:selectBooleanCheckbox id="checkBox1" value="false" onclick="getIndexOfSelectedToremove(this)" valueChangeListener="# {MSPSSecurityProfileDetailsBean.getRemoveSelectableItems}" title="click it to select or deselect" style="width:14px;height:14px;"/>
</h:column>

<h:dataTable>


My javascript:

function getIndexOfSelectedToremove(val){
alert(val.value);
}

Hi Burkhard,

Thanks for your answers.I have one more doubt.

If I create the account object inside the run method,what will happen?

I got answers like each thread has a copy of the balance variable,eventhough i make both the moethods synchronized.

Is this because of
BankAccount account =new BankAccount();
is inside the run() method ?



Thanks Deepa
Hai,
Please clear my doubt. In the following program, three threads accessing the same account.


My doubt is :
As withdrawal method is a synchronized one,only one thread is allowed to make the withdrawal.After it finishes the withdrawal,second thread will withdraw.Eventhough the balance is Rs.90 after first thread's withdrwal,the second thread reads the balance as Rs.100.Why is this so?
i)does the threads read the balance from the thread's local or from main memory?
ii)After each thread making a withdrawal,will it store the balance in main memory or thread's local?when it gets stored in main memory?

iii) the balance variable is accessed from main memory or from thread's local each time it reads.

iv) what are the values in thread's local and will be in main memory?

Thanks in advance

Hai,
I wanted to know where the "account" object gets stored(stack or Heap).And will the threads have the separate copy of the objects or not?
