Background-color dynamic change
Hi all!!
As I said in the title I'm trying to change dynamically the background-color
parameter of a <div>. I tried with this code :
<div t:type="loop" t:source="instanceList" t:value="instances">
<div id="Liste" t:source="instanceState" t:value="color"
style="background-color: ${color}">
${instances.nomInstance}
</div>
</div>
And the java class is like this :
@Property
private Instances instances;
@Property
private String color;
public List<Instances> getInstanceList()
{
try {
return (List<Instances>) instanceManager.sortAll();
} catch (BusinessException e) {
e.printStackTrace();
return null;
} catch (TechnicalException e) {
e.printStackTrace();
return null;
}
}
public String getInstanceState()
{
InstanceService service = new InstanceService();
color = service.instanceState(instances.getIdAo());
return color;
}
Apparently it's good but the background-color doesn't change... Even if I
try to simply return color = "red" there are no changes... and neither error
message... So I'm quite disappointed, I don't see where the program bugs...
If anyone can help me it would be very great ^^
ps : Excuse me for the grammar, English is not my native language ^^

Hello
Thanks, that was the problem indeed. So I change to that :
<div t:type="loop" t:source="instanceList" t:value="instances">
<div id="Liste" style="background-color: ${getInstanceState()}">
${instances.nomInstance}
</div>
</div>
And it works!!!!!
But now I have another problem (yeahh I never stop ^^) with my service this
time. Here is the service class :
@Inject
@Service("borneManager")
private BorneManager borneManager;
private IsoMsgServiceImpl service;
/*
* (non-Javadoc)
*
* @see
* com.atosworldline.effia.applira.web.services.BorneService#borneState(
* long)
*/
public String borneState(long id) {
List<Bornes> bornes = null;
service = new IsoMsgServiceImpl();
String color = "green";
try {
bornes = (List<Bornes>) borneManager.findByIdAo(id);
} catch (BusinessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (TechnicalException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
for (Bornes borne : bornes) {
String colorBorne = service.borneStateForInstance(borne.getId());
if (color == "green") {
color = colorBorne;
} else if (color == "orange") {
if (colorBorne != "green") {
color = colorBorne;
}
} else if (color == "red") {
return color;
}
}
return color;
}
But when I try to run it, my borneManager bean is not injected as in the
page class...
I don't really see were is the problem.

Re: Background-color dynamic change

I don't believe your getInstanceState() method is being called,
therefore you are not setting your color. You have:
<div id="Liste" t:source="instanceState" t:value="color"
style="background-color: ${color}">
Tapestry is ignoring the t:source because there is no t:type
specified. If you look at the HTML generated, you'll probably see:
<div id="Liste" style="background-color: ">
