Bean Utils Problems transferring Indexed Properties.....String []-->Integer []
Hi
I am trying to commons-beanutils to transfer data from a String [] in a
form-bean
to a data bean with a Integer[].
My String[] has three elements when it comes from the ActionForm.
BeanUtils.populate(bean,map); copys only the first element of the String[]
into the integer array.
I searched the archives and the nightly build of commons is supposed to
solve the problem, i tried and it did not help.
Can any one help me with this issue, i am stuck.
regards
Rajesh

Subject: RE: Tiles: pass "title" value to header page
I think I know what your issue is here because I had a problem with this a
couple of days ago. When I went to use the title attribute in the header,
it was null. I had to do this in my basicLayout page...
<tiles:useAttribute name="title" classname="java.lang.String"
ignore="true"/>
<tiles:insert attribute="header">
<tiles:put name="title" value="<%=title%>"/>
</tiles:insert>
It didn't really make sense to me why the title attribute didn't trickle
down into the header. It seems like a scope issue and I was trying
different ways of declaring scope but didn't have any luck. This is the
only way I could get it to work.

What would you have twice? The tiles:put or the tiles:getAsString?
Why not just define the title in the ApplicationResources.properties file?

It's not clear (to me) what you want to do.
Off-hand (and if I am guess-timating correctly) I can think of about 10
unique ways to avoid duplication of code (or in this case, tiles
configuration)

In concept, you would only want to do this if you wanted a different title
for each view.
I can provide (very basic) code samples for what I consider to be "Best
Practices with Tiles". Let me know if you would like a copy.

BeanUtils.describe and BeanUtils.populate indexeed properties...
Posted by Rajesh Kalluri <rk...@manduca.com>.
I saw a similar issue on the archive but did not see what the solution to
this was, so decided to ask the same question again.
Do BeanUtils.describe and BeanUtils.populate supposed to handle indexed
properties?
Suppose I have this JavaBean:
public class NameBean {
private String[] name;
public String[] getName() {
return this.name;
}
public void setName(String[] name) {
this.name = name;
}
public String getName(int index) {
return this.name[index];
}
public void setName(int index, String name) {
this.name[index] = name;
}
}
NameBean nameBean = new NameBean();
nameBean.setName(new String[] {"John", "Paul", "Jack"});
Map properties = BeanUtils.describe(nameBean);
I would expect the following code to return a Map containing:
name[0]="John", name[1]="Paul", name[2]="Jack"
but instead,
I get name="John".
Only the first element is considered.

Rajesh

RE: Bean Utils Problems transferring Indexed Properties.....String []-->Integer []
Posted by Rajesh Kalluri <rk...@manduca.com>.
Craig,
I have this Integer[] as part of a bean and String [] as part of a form bean
Do i have to register custom describe to transfer data from a bean having a
string[] to an Integer
in order to use BeanUtils.populate(). If so do you have an example.
// I am trying to transfer liek this.
Map Properties = BeanUtils.describe(formBean);
BeanUtils.populate(dataBean,map);
DATA BEAN:
/**
* The authors of the article
* <p>
*/
private Integer[] authors;
/**
* Returns the authors.
* @return Integer[]
*/
public Integer[] getAuthors() {
return authors;
}
/**
* Sets the authors.
* @param authors The authors to set
*/
public void setAuthors(Integer[] authors) {
this.authors = authors;
}
FORM BEAN:
/**
* The author of the article
* <p>
*/
private String[] authors;
/**
* Returns the authors.
* @return Integer[]
*/
public String[] getAuthors() {
return authors;
}
/**
* Sets the authors.
* @param authors The authors to set
*/
public void setAuthors(String[] authors) {
this.authors = authors;
}
