I'm using xf:itemset at the moment. Never seen the jx:ForEach before which gets back
to one of my original questions:
Are there any docs for jxForms yet? If so, where?
Regardless of whether I use the itemset or not, I can get my checkboxes to display
correctly on the screen.
The problem comes when I want to capture the state of the checkboxes.
If I define my model in javascript with a "var results[""]" then it works okay. I get
back an array of strings.
If I define my model in a Java Bean and pass it to the form after instantiating with
"var model = new Packages.path.class()",
then it doesn't work. If the bean defines the results as a String[], then I get the
cast exception (previous email). If I define results as a single String, then I get
the id of the first checked checkbox, but none of the others. I tried initializing my
array of Strings in my java class but it didn't make a difference whether it was or
not.
Right now I'm going with the slightly kludgy workaround of using a javascript model
for the form and then copying it to my Java Bean after submission.
