Validate my custom properties.

[naveenkumar]

hi all,
In my application i need to validate a check boxs, i added two meta  properties in my workflow with type as d:boolean, when approver uncheck both the check box and he clicks approve button i need to validate and show an error message.

In few forum it mentioned validation is done by using constraints in *model.xml.. but i need to check for two properties at the same time i need to display my own error message…

Thanks
Naveen

Is this possible without changing the java classes?? If its done by changing Java classes,then suggest an idea??

Thanks

Cross-property constraints are not supported without changing java code.

Can you guide me to do this using java classes?? Is there any wiki links related to this??

Thanks

Nice… How did you manage to show your own error message? I would like to do this also.

I'm interested too, but in thinks I will never have any answer 😕

I actually do UI validation through javascript in the workflow-options.jsp file(classpath:/jsp/workflow/start-workflow-wizard/workflow-options.jsp).

All, I did was attach my own validation function to the Next button's onclick(). Then I check the values in the DOM and make sure they are what I want, otherwise I don't let the user go to the next page.

Hope that helps out.

I would be interested to see an example of your code if it's possible.
At the other hand, I think this more complicated to do this on a generated button (the one that you define for a transition and not just for the workflow initialisation).
