Hello Community,
I'm quite new to Struts2 (or even Struts anyhow) and I'm struggling with
a Problem .
My multiline Form send's via the validation the fieldError data as
shown below to my jsp. Because I do have a multiline form my return of
the Object key is something like:
myrecords[3].myfieldName. This information is not the best for my Users
so I want to break it up in something like : At row 4 (because it starts
counting 0) in Column MyFieldName is Error blablabla... Therefor I need
to extract the index and the Fieldname. Well the problem is the index.
As you can see in my example below I have extracted the index (in my
example 3 ) from the Object key. And that works pretty fine. But, and
now comes my Problem, it's still a String and I can't add the int 1 to
it. I have tried several things in different combinations but nothing
worked out.
<s:iterator value="fieldErrors" >
<s:set name="r2"
value="%{key.substring(key.indexOf('[')+1,key.indexOf(']'))}"/>
<s:set name="r3" value="%{#r2.trim()}"/> //howto convert r3 to a
integer?
<s:property value="r3"/><br>
</s:iterator>
Thanks for any help
Uwe
