Hi all,
I have a problem with this type-conversion thing.
http://struts.apache.org/2.x/docs/type-conversion.html
I am trying to dynamically fill a table. I have a bean
Person and Person has "List<House>".
What I did - step by step.
1 - I defined "List <House> houseList" in the PersonAction class. (Also
Getter and Setter Methods)
2 - create a file. in the resources directory (the path is the same with the
PersonAction)
PersonAction-conversion.properties
KeyProperty_houseList=id
Element_houseList=org.tutorial.model.House
CreateIfNull_houseList=true
3 - And in the jsp file I put this as it is said in link above.
<s:iterator value="houseList" id="house">
<s:textfield name="houseList(%{house.id}).name" />
</s:iterator>
(House has a String field "name")
4 - The values are not shown in the jsp file. So I cannot get them in the
action too.
But when I change the name of the <s:textfield> to "name" it writes the
names on the textboxes. But still I cannot get the list when I press on the
update button.
I expect it to fill the houseList when I go back to Action class. Is it
wrong?
Can you see what I am doing wrong or something missing?
Thanks for reading.
I'm just guessing here, but you have a suspicious looking OGNL expression:
<s:textfield name="houseList(%{house.id}).name" />
I'd start by trying these variations:
<s:textfield name="%{houseList(house.id).name}" />
<s:textfield name="%{houseList(#house.id).name}" />
<s:textfield name="%{#houseList(house.id).name}" />
<s:textfield name="%{'houseList('+ house.id + ').name'" />
Try breaking that OGNL expression out into a series of s:property tags
to see which bits of the expression are / are not resolving as you expect.
