[S2] s:if in 2.0.11
I am upgrading to 2.0.11 from 2.0.9 and got this error
SEVERE: Servlet.service() for servlet jsp threw exception
org.apache.jasper.JasperException: /jsp/content/findAcrResults.jsp(6,0)
According to TLD or attribute directive in tag file, attribute test does
not accept any expressions
for this line in my jsp
<s:if test="${resultSize} > 0">
I changed it to
<s:if test="%{resultSize>0}" >
Now the error went away. But the statement never evaluated true. I
took out the s:if statement, the result showed up corrected. resultSize
is a request attribute.
Please advice,
Jane

RE: [S2] s:if in 2.0.11
Posted by "Jiang, Jane (NIH/NCI) [C]" <ji...@mail.nih.gov>.
I changed
<s:checkbox name="selectedItems" fieldValue="${acr.id}"
value="itemsSelected[${acr_rowNum}-1]" />
to
<s:checkbox name="selectedItems" fieldValue="%{#acr.id}"
value="%{itemsSelected[#acr_rowNum -1]}" />
I assume acr should be in pageContext. Now I am having no error but the
value is not populated. What did I do wrong?
Thanks,
Jane

Thanks so much for your explanation. I changed my statement to
<s:if test="%{#request.resultSize>0}" >
That works. I don't want to move result size to value stack yet since I
need to move on and see what other problems might exist for the upgrade.
Now I got a similar problem. My result is displayed in a displaytag
table.
<display:table name="acrs" class="its" id="acr" pagesize="${pageSize}"
report="true" ..
One of the column is a checkbox.
<display:column>
<s:checkbox name="selectedItems" fieldValue="${acr.id}"
value="itemsSelected[${acr_rowNum}-1]" />
</display:column>
I got this error
org.apache.jasper.JasperException: /jsp/content/findAcrResults.jsp(17,2)
According to TLD or attribute directive in tag file, attribute
fieldValue does not accept any expressions
How can I get the value of acr.id?
Thanks,
Jane

You're trying to mix expression languages.
%{resultSize > 0} assumes that resultSize is on the
value stack, most likely exposed via a public getter
on your action. This is arguably a better practice
anyway.
If the list itself is available on the stack then you
can call the size() method on the list in your <s:if
test="..."> OGNL expression and do away with the
request attribute altogether, which is arguably
cleaner anyway.
