Typical Symptom Description

I have been trying to test the XYZ example. I can compile the program, run it in WebHub, and get the homepage up from the server. But when I include the (~webdatagrid1.execute~) code, I never receive any data. Even the html source shows an empty table without error messages.

Confirmation of Problem

Look on the Connected > Current panel in WebHubView, and check whether two or more processes are serving the same AppID (for XYZ). If they are, the HUB process will ALWAYS get the call and your custom process will never get a chance to respond. That is why the HTML appears, but no data.

Solution

This is a simple configuration issue.

Tell the Hub to serve a different AppID. We recommend using 'hubvers' inside the Hub process. Make sure your custom EXE is running. Confirm that you now see both the HUB and XYZ processes listed on the Connected > Current panel and that they each show the correct AppID.

Test again. This time the call will get to your custom EXE, and you will see full data on its Output panel, as well as in your browser.
