You’re welcome Ilja, I’m glad the example has helped you.

There are plenty of other code solutions on the site and if you look at the resources blog, you will see other resources that I recommend.

Happy New Year,

Niall

Dear Niall,

I have been busy for two days just trying to find a way to add the total of a Column, but could not find anything usefull on any website sofar…untill I read this article.

The advise of “Control”+”Shift”+”Click” worked out well, I finally see a total, Thank you so much.

I will read your article again and also the links provided as I am sure they will be useful too.

I am just a beginner, and I am happy to have at least succeeded in completing something at the end of this day. Thanks, and happy new year 2012.

Best regards,

Ilja

John,

Thank you very much for pointing that out. The oneOfChild is much cleaner.

I have implemented it in the form and uploaded a new version.

Thanks,

Niall

Niall:
Great post. Very impressive sample.
I should point out that your code for manipulating fills could be more terse.
Instead of:
var vName = price.somExpression;
var fieldObj = xfa.resolveNode(vName + “.ui.#numericEdit.border.fill”);
fieldObj.presence = “visible”;
try:
price.ui.oneOfChild.border.fill.presence = “visible”;

thanks,

John
