EL buggy? this shouldn't happen
hi all!
while trying to figure out how indexed/mapped properties work I get some strange
behaviour - I'm pretty sure this doesn't conform to standard (hope I'm
mistaken):
<logic:iterate id="foo" indexId="ctr" name="mappedTest" property="testPrimKey">
<tr>
<td>${foo}</td>
<td>${ctr}</td>
<td>testPrimKey[${ctr}]</td>
</tr>
</logic:iterate>
evaluates to:
<tr>
<td>k1</td>
<td>0</td>
<td>testPrimKey[]</td>
</tr>
<tr>
<td>k2</td>
<td>1</td>
<td>testPrimKey[]</td>
</tr>
...
where the k1, k2.. are the expected values of key "testPrimKey" in the
HashMap put under "mappedTest" in the PageContext
BUT ${ctr} gets evaluated to different values
I'm using struts1.1 and tomcat 5.0.19
so whose wrong?
me or the result ???
thanks for enlightenment!
Axel

Re: indexed property problem
Posted by Axel Groß <ka...@iaeste.at>.
went through the beanutils code to find the reason for the
ArrayIndexOutOfBounds.
found that it doesn't use my setter method, which would adjust the array
size, but just my getter method (which returns an array, which isn't big
enough); moving over to lists instead
so i suppose my html was correct.
the html:text issues are still not working anyway :/

Re: indexed property problem
Posted by Axel Groß <ka...@iaeste.at>.
i was trying to figure out how to use indexed properties.
in the end I want to pass a collection of name/value pairs to the form,
which the user can edit and then check those and maybe pass the new values
to business logic.
at the moment i'm trying to do this with two String[], one called keys the
other one called values.
For passing those values to the browser, I try using indexed propertie.
As I'm not sure how it has to look like in html so that struts will
populate the ActionForm I'm stuck with the html:text tag, which I can't
make work the way I'd like it to
testPrimKey is a String[] which should put values into the html,
which should get put into the ActionForm, which has an indexed
property called 'keys'
so if I'm guessing right it should look in the end like
<input type="text" value="k1" name="keys[0]" />
but if I have that i get a
ServletException: BeanUtils.populate
..(RequestUtils.java:1254)
root cause
ArrayIndexOutOfBoundsException
java.lang.reflect.Aray.set(Native Method)
...
so maybe that means, the html syntax is ok; but i don't know..
:/

I thought you were trying to get a mapped property.
What does the structure look like? I cant see what you're drilling to.

doesnt exist in struts 1.1,right?
should be evaluated anyway...
i tried now
<html:text name="mappedTest" property='testPrimKey[0]' />
-> still
<input type="text" name="testPrimKey[0]" value="" />
should that version work? if so it doesnt seem to be the EL part which is
amiss.

indexed property problem

Hi Mark!
thanks for your answer

evaluates to as it should to testPrimKey[0], testPrimKey[1]..
( i did a stupid mistake in my code ),
On 2004-03-18 at 13:25:22 +0100, Mark Lowe wrote:
> ${testPrimKey[ctr]}
that actually evaluates to nothing
but ${mappedTest.testPrimKey[ctr]}
gets the right result
BUT my original intention (to use it with html:struts) still fails, because
the tag doesnt populate the value for the indexed property:
without using the indexed property:
<html:text name="mappedTest" property='testPrimKey'></html:text>
-> is as expected:
<input type="text" name="testPrimKey" value="[Ljava...{right object reference}" />
with using the indexed property
<html:text name="mappedTest" property='testPrimKey[${ctr}]' />
-> doesnt put value attribute:
<input type="text" name="testPrimKey[0]" value="" />
<input type="text" name="testPrimKey[1]" value="" />
...
if anybody could help me with that one, i'd be relieved

${testPrimKey[ctr]}
or perhaps with the wrappers
<c:set var="key" value="${testPrimKey[ctr]}" />
${key}
what does that do?

sorry!
in my code (on the other machine),
I reference once the not existing EL variable crt
so the code i posted works as expected
sorry again :(( (should have taken a break)
