Hello,
I am getting the following error while trying to use the netui:texbox tag.
Any ideas?
Thanks,

Tim--
Looks like you've got a NetUI tag like:
<netui:textBox dataSource="{actionForm.username}"/>
For Beehive/NetUI tags, this should look like:
<netui:textBox dataSource="actionForm.username"/>
For the sake of clarity and not confusing "{...}" with JSP 2.0 EL
expressions as "${...}", NetUI tag dataSource attributes should not
include curly braces.
Hopefully, we'll get some documentation on the basics of databinding
online soon. In the meantime, hope this helps!

Hi Tim,
try removing the braces from the datasource attribute in the JSP.
I.E.
<netui:textBox dataSource="actionForm.username"/>
rather than
<netui:textBox dataSource="{actionForm.username}"/>
Hope that helps. Regards,
Carlin

Re: netui:textbox
Posted by Daryl Olander <do...@gmail.com>.
In Beehive, we have dropped the '{' and '}' from all dataSource
attributes for expressions. All other attributes on the tags take the
standard JSP 2.0 format ${xxxx}. We dropped the braces because we
felt it confusing to have the dataSource and JSP expressions being so
similar. We are in fact, much closer to Struts now.
