Bind an edit field inside a custom control to a form field programmatically

I have a notes form with a number of fields like city_1, city_2, city_3, etc.

I have an XPage and on this XPage I have a repeat.

Repetition is based on an array with ten values ​​1 - 10

var repArray = new Array() ;
for (var i=1;i<=10;i++) {
repArray.push(i) ;
}

return (repArray);

Inside the replay, I have a custom control that is used to handle city_1 fields through city_10

The repeat has a custom docdatasource property that is passed to It also has a custom string property called cityFieldName that is calculated using the repeat name of the collection, so the first line of the repeat is city_1, the second is city_2, and so on.

Editable text box in custom control is linked using EL formula compositeData.docdatasource [compositeData.cityFieldName]

This works great, but every time I add new fields I have to remember to create a new custom property and then link to it on the parent page.

I would like to just calculate the data binding like

compositeData.docdatasource['city_' + indexvar]

where indexvar is a variable representing the current line number.

Is it possible? I read that you cannot use "+" in expression language.

First: you don't need an array for the counter. Total 10 will do (number) - repeat 10 times. But you can build an array of arrays:

var repArray = [];
for (var i=1;i<=10;i++) {
   repArray.push(["city","street","zip","country","planet"]) ;
}
return repArray;

then you should be able to use

#{datasource.indexvar[0]}


to tie the city

#{datasource.indexvar[1]}

to tie the street. and etc.

A little shy of the danger of messing around with the sequence of an array, if that's a concern you should delve deeper into the use of an object here.

compute javascript and use something like

var viewnam = "#{" +  (compositeData.searchVar )+ "}"
return viewnam


make sure this is computed on page load in the custom control

I have never been able to do an add to EL, but I was very successful in just calculating the field names outside of the custom control and then passing those values ​​to the custom control.

I can send you some working code if you would like me to give a presentation.
