shown variable value in -input
hi struts-users,
perhaps someone can help me? :-)
i have a problem with the <html:text>-tag. i dont surely understand what
i have to put in the value-parameter. it is stated that i can use
runtime-expressions, but i definitely dont get it running.
my tag looks something like:
<html:text name="nameOfJSPBean"
property="nameOfPropertyOfJSPBean"
value="" >
i just want to get a text-input, which is filled with the same
value of my JSPBean, in which the input of the user will be pasted upon
population.
so i tried things like:
(Yeah, i really know, that this can't work ;) )
<html:text name="nameOfJSPBean"
property="nameOfPropertyOfJSPBean"
value="<%= nameOfJSPBean.getNameOfPropertyOfJSPBean() %>" >
and the runtime expression thing, explained in the BeanTagDeveloperGuide
like:
<html:text name="nameOfJSPBean"
property="nameOfPropertyOfJSPBean"
value="nameOfPropertyOfJSPBean" >
but also this doesn't work ... the String "nameOfPropertyOfJSPBean" is
just interpreted as String.
can anyone give me a hint, what i am doing wrong and how to solve it?
thanx for your help in advance!
best regards,
alf
ps: i use VA4J 3.5.3. is it perhaps a bug of that ide???

Aren't you missing the '/' at the end of the Text Tag?
If your tag is like this:
<html:text name="nameOfJSPBean"
property="nameOfPropertyOfJSPBean"
value="" >
just add an '/' at the end of the tag:
<html:text name="nameOfJSPBean"
property="nameOfPropertyOfJSPBean"
value="" />
Struts tags always needs to be enclosed (Its not like HTML in that aspect).

Hi Gollo,
now after a day of search i have found out, why the bean value wasn't
displayed.
you are right, the value would be shown ... IF the database is there! ;)
another teamdeveloper has switched the database without giving me a
hint.
sorry all for not checking that further.
thanx alf

Hi Alf,
Yes, removing the value attribute should do exactly as you want. From
the documentation
value: Value to which this field should be initialized. [Use the
corresponding bean property value] [RT Expr]
The default value of value (this is confusing :-)) is described in the
square brackets. So if you don't specify the value attribute, the
default will be taken, which is to use the value from the bean.
Gollo.

Hi Gollo,
thanks for your help, but the population to the bean isn't my problem,
that works well.
my problem is displaying the value of that JSPBeanProperty, that was
entered already or read from a database.
in 'normal' jsp-development i would use:
<input type="text" name="propertyname" value="<%= bean.getPropertyname()
%>">
and for that bean.getPropertyname()-call i search the solution with the
html:text-tag
Do you have another idea???
Regards,
alf

Try removing the value attribute altogether, eg
<html:text name="nameOfJSPBean"
property="nameOfPropertyOfJSPBean">
That should populate the text field with the value of the field in
nameOfJSPBean.
Cheers,
Gollo.
