Re: Component with a persist attribute inside a loop

[Joachim Van der Auwera]

You should pass the "usage" string as context parameter on the action link.
The problem is that the url for each of the events in the loop are the same.

Kind regards,

Hi,

I'm trying to use my own component inside a loop and I have a problem
when there is a "persist" annotation on attributes.

I want to loop with my component named "test" in a page like this :

<t:zone t:id="refreshZone"/>

<t:loop source="0..2" value="testId">

   <t:test usage="${usage}"/>
</t:loop>

The component contains a string attribute "usageValue" that will be
displayed in the refreshZone.
This attribute comes from the parameter "usage". I put my value on the
setupRender method.

The class of the component is like this :
public class Test {

        @Parameter
        private String usage;

        @Persist
        @Property
        private String usageValue;

        @Inject
        private Block refreshBlock;

        boolean setupRender(MarkupWriter writer) {
                this.usageValue = usage;
                return true;
        }

        Object onActionFromClick() {
                return refreshBlock;
        }
}

And the tml :
<t:block t:id="refreshBlock">
        ${usageValue}
</t:block>

<t:actionlink t:id="click" t:zone="refreshZone">Click
me</t:actionlink><br/>

The controller of the page is quite simple and returns an usage for a
given number
public class ContentTest {

        @Property
        private int testId;

        public String getUsage() {
                if (testId == 0) {
                        return "pix";
                } else if (testId == 1) {
                        return "zoom";
                } else if (testId == 2) {
                        return "thumb";
                } else
                        return "";

        }
}

Here is the problem : when I click on the link, the value displayed is

always "thumb" ! I should have "pix" displayed with the first link, "zoom" with the

second ...

I tried to put an id, but the behaviour is the same :
<t:loop source="0..2" value="testId">
   <t:test t:id="testId" usage="${usage}"/>
</t:loop>

And if I don't use the loop, there is no problem :
<t:zone t:id="refreshZone"/>
<t:test usage="literal:pix">
</t:test>
<t:test usage="literal:zoom">
</t:test>
<t:test usage="literal:thumb">
</t:test>

If I use these lines, i have the right behaviour.

What's going on ?
