asadim2 Rerendering loses my values -except the last one!
Controller:
VF page:
Problem 1:
When the commandLink on each row except the last one is clicked, I get a new row but all the input fields reset to their original values. However if I change the value of the last row and click the link on the last row, the value is remembered.
Problem 2:
On click of the link, if I rerender the page instead of pageBlock I don't get a new row. Any ideas why?!
To make it simple you can directly copy/paste above code into your org and test.
public class TestRerenderController
{
public List<String> titles { get; set; }
public List<VO> vos { get; set; }
public TestRerenderController()
{
titles = new String[]{'Title A', 'Title B', ' Title C'};
vos = new List<VO>();
vos.add(new VO('text a'));
vos.add(new VO('text b'));
vos.add(new VO('text c'));
}
public void hi()
{
titles.add('Title D');
vos.add(new VO('text d'));
}
public class VO
{
public String text { get; set; }
public VO(String s)
{
text = s;
}
}
}
VF page:
<apex:page controller="TestRerenderController" id="p">
<apex:form id="f">
<apex:pageBlock id="pb">
<apex:variable value="{!-1}" var="index"/>
<apex:repeat value="{!titles}" var="title">
<b>{!title}</b><br/>
<apex:variable value="{!index+1}" var="index"/>
<apex:inputText value="{!vos[index].text}"/><br/>
<apex:commandLink action="{!hi}" value="Add D row" reRender="pb"/>

</apex:repeat>
</apex:pageBlock>

Note:<apex:variable> does not support reassignment inside of an iteration component, such as <apex:dataTable> or <apex:repeat>. The result of doing so, e.g., incrementing the <apex:variable> as a counter, is unsupported and undefined.

Just try below code
public class TestRerenderController { //public List<String> titles { get; set; } //public List<VO> vos { get; set; } public List<VO1> listOfVO1{set;get;} public TestRerenderController() { //titles = new String[]{'Title A', 'Title B', ' Title C'}; listOfVO1 = new List<VO1>(); listOfVO1.add(new VO1('text a','title a')); listOfVO1.add(new VO1('text b','title b')); listOfVO1.add(new VO1('text c','title c')); /*vos = new List<VO>(); vos.add(new VO('text a')); vos.add(new VO('text b')); vos.add(new VO('text c')); */ } public void hi() { system.debug('-------------------------'+listOfVO1); listOfVO1.add(new VO1('text d','Title D')); } /* public class VO { public String text { get; set; } public VO(String s) { text = s; } }*/ public class VO1 { public String title{SET;GET;} public String text { get; set; } public VO1(String s,String t) { text = s; title =t; } } }Page<apex:page controller="TestRerenderController" id="p"> <apex:form id="f"> <apex:pageBlock id="pb"> <apex:repeat value="{!listOfVO1}" var="t"> <b>{!t.title}</b><br/> <apex:inputText value="{!t.text}"/><br/> <apex:commandLink action="{!hi}" value="Add D row" reRender="f"/> <br/><br/> </apex:repeat> </apex:pageBlock> </apex:form> </apex:page>Yes there is not any error in you code but salesforce getting value in by your way on page.
