Edit box in repeat control with default value does not update on delete - xpages

Question

I have a Repeat control in which I have a edit box which has passed a default value.There is a Delete button to delete that row.
just for test I have used a computed field along with the edit box.Computed field is also passed the same value as edit box.Now both computed Field and Edit Box has same value,When I click on Delete button randomly,it gets delete but only computed field updates properly in repeat control wherever deleted,
In case of Edit box,it shows the last record disappears.
So the issue is, the value in edit box does not get update like computed field does.I have done the test by writing following code.
<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">
<xp:this.data>
<xp:dominoDocument var="document1" formName="testing">
</xp:dominoDocument>
</xp:this.data>
<xp:inputText id="inputText1" multipleSeparator=",">
<xp:this.defaultValue><![CDATA[#{javascript:var v:java.util.Vector = new java.util.Vector();
v.add('1');v.add('2');v.add('3');v.add('4');v.add('5');v.add('6');
return v;}]]></xp:this.defaultValue>
</xp:inputText>
<xp:br></xp:br>
<xp:repeat id="repeat1" rows="30" var="r" indexVar="i" first="0">
<xp:this.value><![CDATA[#{javascript:return getComponent("inputText1").getValue();}]]></xp:this.value>
<xp:br></xp:br>
<xp:div style="text-align:center">
<xp:label value="#{javascript:r}" id="label1"
style="text-align:center">
</xp:label>
<xp:button value="Delete" id="button1">
<xp:eventHandler event="onclick" submit="true"
refreshMode="complete">
<xp:this.action><![CDATA[#{javascript:var v:java.util.Vector = getComponent("inputText1").getValue();
if(v != null){
var sdtString = getComponent("inputText2").getValue();
if(v.contains(sdtString))
v.remove(sdtString);
};}]]></xp:this.action>
</xp:eventHandler>
</xp:button>
<xp:inputText id="inputText2">
<xp:this.defaultValue><![CDATA[#{javascript:getComponent("label1").getValue();}]]></xp:this.defaultValue>
</xp:inputText>
</xp:div>
<xp:br></xp:br>
</xp:repeat>
</xp:view>
This is the example code for testing to get the exact issue.
Edit 1: Real Scenario
We have an application to select multiple dates for a meeting and hence using the notes free time we mark multiple dates and then users are allowed to edit/delete the same in another window..Since, it was not possible/feasible enough to save all the fields in SSJS, we rather preferred binding each field with the data-source under the repeat control by using custom properties of the custom control (hope I am making some sense). Every fields is mapped as #chintan pointed out as follows:
dataSource[compositeData.to]
As described in the first part of the question the fields are not getting updated since we set them using default values. However, based on the suggestion we tried to set the field using the script library which does work well, however, might seem stupid but it messes the date field. When we set the value using the following:
var d:java.util.Date = new java.util.Date(compositeData.selectedDate);
getComponent("from").setValue(d);
It jumbles up the month, date and year field and shows a complete different value (the same code works well when put as the default value).
Hope this makes sense.
Any kind of solution can be appreciated.

Answer 1

inputText2's defaultValue gets executed only once at first page load. Then the XPage memorized that repeat 1 has inputText2 defaultValue 1, repeat 2 has inputText2 defaultValue 2 and so on.
Example: as you can see in print log, inputText2's defaultValue doesn't get calculated again after deleting row 3 and later row 1.
Turn it around and set inputText2's value in label1's value code:
<xp:label
value="#{javascript:getComponent('inputText2').setValue(r); r}"
id="label1"
style="text-align:center">
</xp:label>
then it will set inputText2's value properly. You don't need inputText2's defaultValue property anymore.
As an alternative you can define inputText2's value property and bind it to a row-specific data source or viewScope variable.

Answer 2

As you described in your "Edit 1 Real Scenario", you want to edit and delete pairs of dates. I created the following example. Instead of dates I just use strings for simplicity. Keep the dates in a viewScope variable and edit/delete them right there:
<?xml version="1.0" encoding="UTF-8"?>
<xp:view
xmlns:xp="http://www.ibm.com/xsp/core">
<xp:this.beforePageLoad><![CDATA[#{javascript:viewScope.dates=[
{"from":"a", "to":"b"},
{"from":"c", "to":"d"},
{"from":"x", "to":"y"}];}]]></xp:this.beforePageLoad>
<xp:br />
<xp:repeat
id="repeat1"
rows="30"
var="r"
indexVar="i"
value="#{viewScope.dates}">
<xp:br></xp:br>
<xp:div>
<xp:button
value="Delete"
id="button1">
<xp:eventHandler
event="onclick"
submit="true"
refreshMode="complete">
<xp:this.action><![CDATA[#{javascript: viewScope.dates.remove(i);
}]]></xp:this.action>
</xp:eventHandler>
</xp:button>
<xp:inputText
id="inputText1"
value="#{r.from}">
</xp:inputText>
<xp:inputText
id="inputText2"
value="#{r.to}">
</xp:inputText>
<xp:button
value="Update"
id="button2">
<xp:eventHandler
event="onclick"
submit="true"
refreshMode="complete">
<xp:this.action><![CDATA[#{javascript: "";
}]]></xp:this.action>
</xp:eventHandler>
</xp:button>
</xp:div>
<xp:br></xp:br>
</xp:repeat>
<xp:text
escape="false"
id="computedField1">
<xp:this.value><![CDATA[#{javascript:
var length = viewScope.dates.length;
var result = "";
for (var i = 0; i < length; i++) {
result += viewScope.dates[i].from + " - " + viewScope.dates[i].to + "<br />";
}
result
}]]></xp:this.value>
</xp:text>
</xp:view>
Create the viewScope variable as an array of objects.
