If so, this is likely the problem. If you use 4.0, please replace Conditional and Foreach in your code with 'If' and 'For'. Those store their state if they are in a form, and similar problems do not occur. Conditional and Foreach have been deprecated. If you use 3.0, please relace Conditional with contrib:FormConditional when in a form. In the long run you may also download the Base library from http://www.t-deli.com and use base:If and base:For instead of Conditional and Foreach. Hope this helps... -mb Scott Wadden wrote: >Actually, I'm getting the same behavior with the ListEdit. > >This seems to work if messageBody is a parameter rather than a regular >property, and I'll do that if I need to, but in this case the >TextArea's value isn't of interest outside the component.
