Are you sure you are using 2.1.0 and not 2.0.1? I just checked the source code for 2.0.1 [1] and it contains the exception you are referring to. But this isn't present in 2.1.0 [2]. In 2.1.0 the parent Form is looked up dynamically if it is null. Anyway, I think the problem is that dataSet is added to protFS before protFS parent form is set. You can fix it by adding the protFS to the form first: form.addTabSheet(protFS); protFS.add(dataSet); Kind regards Bob [1]: http://svn.apache.org/viewvc/click/tags/click-2.0.1/framework/src/org/apache/click/control/FieldSet.java?view=markup [2]: http://svn.apache.org/viewvc/click/tags/click-2.1.0/framework/src/org/apache/click/control/FieldSet.java?view=markup > Bob Schellink wrote: >> Hi Sven, >> >> On 26/07/2010 22:27, Sven Pfeiffer wrote: >> >>> I'd like to add a FieldSet to tab in a TabbedForm, my code looks like >>> this: >>> >>> TabbedForm form = new TabbedForm("form"); >>> FieldSet protFS = new FieldSet("protocol"); >>> FieldSet dataSet = new FieldSet("data"); >>> >>> ... adding fields to dataSet >>> >>> protFS.add(dataSet); // this crashes >>> form.addTabSheet(protFS); >>> >>> The line protFS.add(dataSet) crashes with the following Exception: >>> java.lang.IllegalArgumentException: Cannot set the FieldSet's form to >>> null >>> >> >> >> In your example above you are adding one FieldSet to another FieldSet, >> not the TabbedForm. >> >> Regardless it sounds as if dataSet has already been added to another >> parent?
