Custom preprocessor exception message not shown in the page

[#1]

Hi, 

We have written a custom preprocessor that gets invoked on page publish to identify if a particular component is present on the page and invoke a workflow for approval before page activation. This all works fine but the custom 'ReplicationException' is not showing up in the page. It shows up in the sites/siteadmin section when i click on "quick publish" button, but the exception is not showing up in the actual page when i click on "Publish Page". In the actual page, it only says "ERROR: Failed to publish the selected page(s)"

I am on AEM 6.4.6.0, any idea why this behavior?

Hi,

When you throw error message from processor e.g

throw new ReplicationException("your custom message");  This message only gets priority when you publish page from siteadmin.

If you want to show different error message when you publish from page then you need to overlay : http://localhost:4502/libs/cq/gui/components/authoring/editors/clientlibs/core.js    <Check quick publish option>.

Thanks

You mean to say this one /libs/cq/gui/components/authoring/editors/clientlibs/core/js/actions/publish.js?

Will check it out, thanks!

yes.. you need to overlay /libs/cq/gui/components/authoring/editors/clientlibs/core/js/actions/publish.js

I am not sure if this is documented anywhere but i was looking into this file /libs/cq/gui/components/common/wcm/clientlibs/wcm/js/publish.js that has the necessary logic in fail/error condition. This is very similar change to quickpublish.js or managepublication.js that were being discussed in the other thread. I tried to overlay it but still no luck

Does the servlet then return the proper message at all, so it will be picked up by the JS?

[prabudossh]

the logic is working in sites/siteadmin area so wondering why it wouldn't work inside the page, I am posting the logic here anyway

@Override

public void preprocess(ReplicationAction action, ReplicationOptions options) throws ReplicationException {

try {

   ....

   if(needReview) {

      startWorkflow(...)

     throw new ReplicationException("The page contains xyz component and it has not been reviewed");

   }

}

catch () {

}

}

Is it documented that the exception message is displayed in the error message to the authors?
