I understand the privacy concern. Why I asked the configuration screen shot is,
In a dynamic grid configuration, when I configure to use "pySelected" checkbox, At runtime, it failed to render and showed "Harness fail" error. The error makes sense, because pySelected property is not part of the pxResults of my dynamic grid. So, I thought I can see the configuration.
Now, I updated my report definition to query the "pySelected" property as well. This is my Report Definition screen print
With this configuration, I am able to configure pySelected for dynamic grid and able to render at runtime.
Grid Screen print :
Runtime Screen print :
With this configuration, I dont see any additional call to DB when click on the header checkbox. It selects all and no call to DB as shown in network trace.
Is my configuration equals to the configuration of issue use case ?
Thanks for your confirmation. Here is grid configuration screen prints.
Operations Tab :
Presentation Tab :
Actions Tab :
If you have the similar configuration but does reproduce the problem, please check the browser developer tools >network tab to find if there is any request is going when you click on the checkbox. if yes, check if there are any actions defined on the header check box, In my configuration, there are no actions defined on the header check box
I've updated my scenario with "Virtual report definition" options. Still, I am not able to replicate the behaviour.
However, With the information we have, I can say that we have done all that we can do through post. And also it seems that the kind of specific configuration is reproducing the issue. This needs more troubleshooting.
