URL/Webpage Memory Leak and Error

Kinetic ERP
, ,
1

When using the dashboard we find the first two have no issues but the “GOLD Documents” throws an error after clicking the “download” control.

We initially tried the browser within a customization but found that it created a memory leak. I’ve also noticed that the “download” control actually functions as intended displaying the ability to ‘Open’ or ‘Save’ the item. Preferred is the customization route but open to using the dashboard if we can get past the errors.

Beginner level user, relying heavily on Epiwidgets in BAQs and BPMs. I do have a programming duo that helps me out quite a bit but we seem to have no luck on this one. Hoping one of you can help guide us in the right direction. Thank you in advance for your time!

I am not very versed in using the dyn webbrowser.

I am a little confused as to why we pulled 3 different instances of the same edv though.
Seems like you just wired 3 identical events to the same edv.

Also, is it intended to apply EmpID as UserID?

4

Each edv leads to a different webpage (wbSite, wbSite2, wbSite3). We need EmpID for the webpage and the user action (on the webpage) gets recorded in another database separate from Epicor.

5

But each edv is the same edv. The code above ran for each part view, just gets the same part view reference.

It just feels like initialize isnt the ideal place to set those browsers up. Is that actually loading webpages on row init? Just a half-cocked idea, I think I would prefer to use a single edv ref. Add a column for those 3 actions that is an icon and then handle the webpage stuff on click.

Thank you @Chris_Conn. I will give that a shot!
