Hi all,

In my struts application, I would like to disable / enable an html:select box based on values selected from another html:select. I am using the following code for enable / disable.

<bean

efine id="myForm" name="myActionForm" type="org.myproj.view.myActionForm" />

<html:select property="select_name" size="1"
disabled='<bean:write name="myForm" property="disableNameFlag"/>' onchange="findAge()">

<html

ption value="0">--- Select ---</html

ption>

<logic

resent name="myActionForm" property="childNameList">
<html

ptionsCollection name="myActionForm" property="childNameList"/>
</logic

resent>
</html:select>

I am setting the value of disableNameFlag to true in the action form bean and <bean:write name="myForm" property="disableNameFlag"/> prints value as true. But html:select is not disabled. Please help.

Thanks.

I'm thinking the issue is probably that the bean:write tag isn't evaluated in that disabled attribute. To be sure you could look at the source html of the select tag to see if the disabled attributed is set to true or if its set to the string <bean:write name="myForm" property="disableNameFlag"/>. If this is the problem you could use the value of your disableNameFlag in a logic:equal tag to control what gets set in the disabled property.

You can't nest tags like that--you need to either use an rtexpr or JSP EL, or as Tom said use logic to determine what gets put in there.
