both components are added to form, so they implicitly get the

};
And now the autocomplete field does not work - well, not completely. If
I
click submit on the form (which gets that state of the checkbox and
field)
I get the expected results, even if the autocomplete field doesn't
populate correctly.
Is there any way I can get round this without forcing a refresh when i
click on the checkbox?

Re: Synchronizing AutoCompleteTextField with a checkbox
That would work as well, yes. I don't know if this is good practice, but the
way I've done it now, which works, is:
tsf = new TableSelectionField(TableNameAutoCompleteTextField);
AjaxCheckBox tncb = new AjaxCheckBox(TableNamesRegexpCheckBox)
{
public void onUpdate(AjaxRequestTarget target)
{
//squelch! does nothing
}
};
tsf.setRegexp(tncb); //don't know if this is good practice, but works
In the model I have methods:
public void setTableNamesRegexpCheckBox(boolean b)
{
this.b_tablenames = b;
}
public boolean getTableNamesRegexpCheckBox()
{
return b_tablenames;
}
public String getTableNameAutoCompleteTextField()
{
return s_tablenames;
}
public void setTableNameAutoCompleteTextField(String s)
{
s_tablenames = s;
}
And in the getChoices method for the textfield I have the following logic:
if((Boolean)regexp.getModelObject())
{
//regular expression
}
else
{
//normal
}

as far as i know wantOnSelectionChangedNotifications will refresh the
page.
AjaxFormComponentUpdatingBehaviour will do an ajax call and won't refresh
the entire page.
