Blank preview sheet dev hub

Anonymous — Wed, 21 Sep 2016 11:04:55 GMT

Hi all,

We are using dev-hub to create a new mashup and we are using the preview sheet as an orientation but when we make some changes in the files associated with the mashup there are some functionalities that starts to going wrong.

The preview page don't show anything. Just a blank background.
When we save the document appears a pop-up with the title "An error occured" but with no description. If reload the page the document keeps the changes.
The button "View" opens an "About:Blank" page.

Any idea? It's a dev-hub bug?

Thank's in advance!

Probably something wrong with your extension; can you post some code?

Hi Aiham,

Thank's for your answer. The extension works fine if access trought the URL. The problem is in the dev-hub, but out of there it's ok.

it may have to do with the wbfolder.wbl file as mentioned in this page: Creating a mashup template ‒ Qlik Sense ;

The wbfolder.wbl is a "helper" for dev-hub to know which files are included in an extension; if the entry file is missing (for mashup the html file), then it will look similar to what you are describing.

regards,

Thank's again Aiham.

I checked the wbfolder.wbl and compared with the example "mashup-template" and seems to be ok. Our wbfolder.wbl contains all the files that is needed to run the mashup.

then, it may be a bug - can you:

- share you mashup (or a similar one to be able to reproduce the issue) ?

- tell which QlikSense version are you using ?

Hi Aiham,

I don't know how but the problem has solved. Anyway, I can't share the mashup and my version is 3.0.

Thank's for all your answers.
