Hi again! For instance: i have a page with the following tml:
<t:progressivedisplay t:id="processingWork" update="show"
initial="block:loadingBlock" />
<t:block id="loadingBlock">
<div align="center"> Working....</div>
</t:block>
<t:block id="workErrorBlock">
<div align="center"> Error! </div>
</t:block>
<t:block id="workDoneBlock">
<div align="center"> Work done! </div>
</t:block>
And in the java file :
@Inject
private Block workDoneBlock;
@Inject
private Block workErrorBlock;
public Object onProgressiveDisplayFromProcessingWork() {
try {
// working code
return workDoneBlock;
} catch (Exception e) {
return workErrorBlock;
}
}
