TAG embeded inside TAG struts 1
Hallo
I need to set dinamically poperties of the TAG struts
Example
I have a easy form like this:
<html:form action="\MyAction" >
<html:text property="myproperty" readonly="true" />
</html:form>
I wont that read-only properties assume value true or false dynamically
using a specific bean that represent for me a mask on with field are
read-only and witch other no...
I have a bean with the properties of the filed and i wont to do someting
like this
<html:text property="myproperty" readonly=<bean:write
name="readonlyproperties" property="myproperty"> />
Obviously in the property myproperty of the bean readonlyproperties
there is a value string that is "true" or "false"
So I wont embed a TAG inside another TAG, in this specific case
beand:write inside a tag html:text
Thanks

The impact on the performances are almost the same if you are using a
JSP 2.0-enabled container, so don't worry.
If you like Struts EL, just use it.

Right, Struts EL is incompatible with JSP 2.0

Thanks Antonio, David
Using the taglib tags-html-el I can use EL expression
But One question.
The differences between tags-html and tags-html-el are not in the tag that are identical.
Why I should prefer to use tags-html? If tags-html-el give me the same TAG and also the possibility to use the EL expression
Are there differences in the performance?
So when it's not necessary to use EL I will import only tags-html and not tags-html-el

You have to use the EL version of Struts tags:

While it's dirty, you can use a scriptlet variable to specify the
dynamic value in a struts html tag.
<% Object isEditable = "false"; %>
<html:text property="myproperty" readonly="<%= isEditable %>"/>
It gets even dirtier when the variable you wish to expose already
exists in some scope. Hopefully you know the scope. Assuming it's
In the request scope:
<% Object isEditable = request.getAttribute("isEditable"); %>
<html:text property="myproperty" readonly="<%= isEditable %>"/>
Did I mention this is a very dirty approach?

This is the problem, you need at least JSP 2.0 and Servlet 2.4 (and
JSTL 1.1.x). What application server are you using?

<html:text property="myproperty" readonly="${readonlyproperties.myproperty}"/>
If I do like this the EL is not evaluated in the STRUTS TAG
I say this because after I tried to put the output whit the JSTL c:out and I see value of the expression correctly
Example
In the request variable myValue="test"
<html:test property="MyPro" value="${myValue}"/> output result "${myValue}" EL not evaluated
<c:out value="${myValue}"/> output result "test" EL evaluated
Why the EL are not evaluated in the STRUTS TAG?
I'm using struts 1.3.8 and JSTL 1.0.6 JSP 1.2

You cannot nest tags in JSP, but you can use EL (if you are using at
least Servlet 2.4):
<html:text property="myproperty"
readonly="${readonlyproperties.myproperty}" />

Could you use JSTL to accomplish the same thing? For example,
<c:choose>
<c:when test='${empty readOnly}'>
<html:text property="myproperty" readonly="false"/>
</c:when>
<c:otherwise>
<html:text property="myproperty" readonly="true"/>
</c:otherwise>
</c:choose>
