Oncomplete of Primefaces component fileUpload is never called - jsf

Question

I have a form upload component on my page and want to make more actions in JavaScript after file upload is complete and page updated.
I put simple log statement to test for "oncomplete" execution, but it never happens.
File is successfully uploaded and other parts of page updated, but no "oncomplete" actions performed.
Here is my component:
<p:fileUpload id="objectUpload1"
fileUploadListener="#{importBackingBean.handleFileUpload}"
mode="advanced" dragDropSupport="true"
invalidFileMessage="Недопустимый тип файла"
invalidSizeMessage="Размер файла превышает 5 МВ"
cancelLabel="#{msg['stop_LABEL']}"
uploadLabel="#{msg['Upload_LABEL']}"
label="#{msg['Choose_LABEL']}" update="results objects_Data"
sizeLimit="5000000" allowTypes="/(\.|\/)(xlsx|xls)$/"
oncomplete="load();" />
And my Javascript:
<script type="text/javascript">
function load() {
console.log('File Uploaded!');
$("button[id*='load']").click();
}
</script>
Button:
<p:commandButton value="Загрузить полисы"
oncomplete="#{importModelBean.needToLoadMore ? 'load();' :'none();'}"
id="load"
action="#{importBackingBean.loadOneRow(importModelBean.current)}"
process="#this" update="mainViewForm:objects_Data" />
When I click the button manually it works just fine. But not getting clicked with oncomplete of filepload.

Answer 1

Using the codes given, I have reproduced this scenario. Although $("button[id*='load']").click(); has been invoked correctly, no log is showing. I am guessing that the button with an id load is set to ajax=”false”. If this is true, then I think that the message was logged the moment console.log('File Uploaded!'); is invoked but was cleared since the page is updated after the load button process. Do you need the log for something? If not, just remove console.log('File Uploaded!'); code and it should work just fine.
EDIT:
I misunderstood you. I thought that your concern was that the message was not logged in the console.
I have tested your codes on two projects (running on two different computers) and I can’t reproduce your problem.
Project 1:
Primefaces 6.0
JSF 2.0
WAS 8.5
IE 11
Project 2:
Primefaces 5.x
JSF 2.0
Glassfish 4.1
Google Chrome
I even tried oncomplete=”alert(‘hello!’)” and it worked fine.
I think that the problem is somewhere else.
For the mean time, can you try the following codes and see if it works:
<p:fileUpload id="objectUpload1"
fileUploadListener="#{importBackingBean.handleFileUpload}"
mode="advanced" dragDropSupport="true"
invalidFileMessage="Недопустимый тип файла"
invalidSizeMessage="Размер файла превышает 5 МВ"
cancelLabel="#{msg['stop_LABEL']}"
uploadLabel="#{msg['Upload_LABEL']}"
label="#{msg['Choose_LABEL']}" update="results objects_Data"
sizeLimit="5000000" allowTypes="/(\.|\/)(xlsx|xls)$/"
oncomplete="rc()" />
<p:remoteCommand name="rc"
oncomplete="#{importModelBean.needToLoadMore ? 'load();' :'none();'}"
action="#{importBackingBean.loadOneRow(importModelBean.current)}"
process="#this" update="mainViewForm:objects_Data" />
