Label component is used in addition to t5 Field component, so for parameter
is required and Field with defined identifier should exist. In case if you
need just an html label element you can use html tag <label>. As I
understand in your code snippet you need something like <span> with some
styling:
<span class="label"> to </span>
To make your code work you should also replace expressions with properties
from java class:
<td colspan="0">
<div style="font-weight:bold; text-align: center;">
<t:outputRaw value="${fromValue}"/>
<span class="label"> to </span>
<t:outputRaw value="${toValue}"/>
<span class="label"> of </span>
<span class="label">${count}</span>
</div>
</td>
public class MyComponent {
//...
public int getFromValue() {
return cursor + 1;
}
public int getToValue() {
return Math.min(cursor + itemsPerPage, collection.size());
}
public int getCount() {
return collection.size();
}
}
As you use just a numbers in your OutputRaw components you can replace them
with simple expression:
<td colspan="0">
<div style="font-weight:bold; text-align: center;">
${fromValue}" <span class="label"> to </span> ${toValue} <span
class="label"> of </span> <span class="label">${count}</span>
</div>
</td>
And in the end of all this, you can introduce message in your component
message catalog:
MyComponent.properties:
pager-format=%s <span class="label"> to </span> %s <span class="label"> of
</span> <span class="label">%s</span>
MyComponent.java:
public class MyComponent {
//...
@Inject
private Messages messages;
public int getFromValue() {
return cursor + 1;
}
public int getToValue() {
return Math.min(cursor + itemsPerPage, collection.size());
}
public int getCount() {
return collection.size();
}
public String getPagerMarkup() {
messages.format("pager-format", getFromValue(), getToValue(),
getCount());
}
}
MyCompoent.tml:
<td colspan="0">
<div style="font-weight:bold; text-align: center;">
<t:outputRaw value="${pagerMarkup}"/>
</div>
</td>
In this case we use OutputRaw as we have html markup in the rendered value.
