struts1 - html:hidden tag
Good morning,
A question about struts1 <html:hidden> tag.
May I know the differences between (1) vs. (2) please?
(1)<html:hidden property="field1" />
(2)<html:hidden property="field1" value="" />
When I load value from popup windows, it seems that default value will
be setup on (1); while (2) always return value="".
Could someone let me know why? I am lost why default value will cause
"problem".
Thanks a lot

Yes, in (2) you're explicitly setting the value--if you're setting it to
what's contained in field1 then leave off the "value" attribute, which
it seems like you were doing, or use something besides a blank for the
value.

If I'd like to load value from datasources into , in my jsp file, (1)
should always be used; otherwise, (2) will rewritten the form value to "" ?

2) actually assigns the value ""
1) gets the value of the property from the formbean if it has been assigned in the formbean.
You may have an action that populates the form by hitting a database, loading the data in the form
and the forwarding to your current page ie before editing a record.
