VA Designer Screen goes Blank

[Matt Lodge]

In the VA Designer application I’m updating an existing Topic. After a decision point I have three branches and I want to edit the condition of one or the branch labels. When I click the label and then click Edit Condition, the whole designer screen goes blank. The filter navigator is still there, its just the main body of the screen that goes white.

Has anyone else experiences this issue?

Hi there,

Haven't experienced such. Though have you tried doing the same incognito or different browser, does the same occur? Or is there perhaps any error written to the system log when this happens?

Kind regards,
Mark

Hello Matt,

Usually this indicates an issue with the VA Topic record, and you should revert back to a previous configuration. Check the following tables where the record is stored and check by hitting 'show XML'. -

Topic (sys_cb_topic) contains the records for each of the topics in the instance.
Topic (sys_cs_topic) stores a particular run time of the topic in sys_cb_topic with a user.

If you duplicate the VA Topic where this issue occurs, the issue should not be reproducible on the duplicated VA topic. If the issue persist, please raise a case with Technical Support.

Best regards,

Brian

Thank you Brian. I managed to revert the topic to a previous version and this worked a treat.

Thank you for your advice.

I used to run into this more on older versions but I can't recall the last time this happened...

Follow Brian's more official advice - I'll just add that you shouldn't need to duplicate the topic to fix the issue - I know I'd never done that but always managed to get around it otherwise. I don't think I have any secret key to it... iirc the issue usually only happens when click one certain thing in the topic, so before you throw the baby out with the bathwater and work off a duplicate topic, try deleting the node/branch first, then save, then readd it and see if that clears it up.
