#Grid#show-when condition
I have a grid with a required field in a User Input node. I have a show-when condition on the grid. Appian allows me to submit the form with a null value in the grid. However, If there is now show-when condition on the grid, Appian does not allow me to submit the form with a null value in the grid.
Why does the show-when condition impact the functionality of a grid with a required field?
I now have to use extra nodes to check if the process variable in the grid is null after the form is submitted....

If a condition hides the field then it will not be rendered at all at runtime and therefore the required condition doesn't exist in the form. If you still want the required condition to apply even when the grid isn't visible you can use FormAPI.hide/show in the onLoad event - this way the grid is rendered in the form.

Hi Tim. I actually want the require condition to apply when the grid is visible, only. But, it is not working when I use 'show only when'...

This can be done by placing the required field within a section. The 'show only when' condition can be then applied to the section. By doing this way, the required validation will be applicable only when the section and in turn the grid gets displayed.
Hope this helps
