I have a javascript that makes a 'tree-view' for me. I managed to already get the tree-view to build trees whose values are taken from my db. The problem is, I want to be able to check the bean of the 'first' array such that if it equals the one located in the second array, it will print/iterate.
Here's a short explanation of my code: the changeItemProducts array is only used to get the 'subject' names. Inside each 'subject' are sub-entries. (For example, Paint has sub-entries like: watercolor, etc). Now, the changeItems array contains the sub-entries (I also added in this array from what 'subject' they come are from).
Now I want to check that if the value of the subject in the changeItems array = value of the subject in the changeItemProducts array, print all the sub-entries. If not, skip it (because it may not have any sub-entries yet in the db) and check the next entries.
Here's my Javascript code for it:
<logic:iterate id="changeItemProduct" name="changeItemProducts">
folCA = insFld(foldersTree, gFld("<bean:write name="changeItemProduct" property="productName" />", ""))
headCA = insDoc(folCA, gLnk("S", makeHeader("Title","#ccccc
headCA.iconSrc = ICONPATH + "ftv2blank.gif"
<logic:iterate id="changeItem" name="changeItems">
<logic:equal name="changeItem" property="productName" value="<bean:write name="changeItemProduct" property="productName" /> ">
insDoc(folCA, gLnk("S", "<bean:write name="changeItem" property="title" />", "/ADM/GetWorkOrders.do?cha
</logic:equal>
</logic:iterate>
</logic:iterate>
The error I get is: equal symbol expected
on this part of the code(at least I think it is this part of the code):
<logic:equal name="changeItem" property="productName" value="<bean:write name="changeItemProduct" property="productName" /> ">
I heard that nesting within a struts tag is not possible. Is there a way to do this? Thanks in advance!

Hi kennethxu!
I tried the code you wrote but I'm getting an error when I load the page:
Generated servlet error:
[javac] Compiling 1 source file
C:\tomcat\work\Standalone\
symbol : variable changeItemProducts
location: class org.apache.jsp.chi_list_js
_jspx_th_logic_equal_0.set
^
1 error
Any ideas? Thanks again!
kennethxu,
When I try to use the bean:define or jsp:useBean with my code, I always end up getting an error. Am not quite sure how to use this though. I had always assumed that when I place my array in an logic:iterate it will be working ok. I also tried using znaps <bean:define> code but I also get an error (see below). Any help would be greatly appreciated. Thanks!
Znaps,
I tried out your code but am still getting an error similar to the one above:
Generated servlet error:

Any help would be greatly appreciated. Thanks!

My last post contained one more mistake (I left out the property="productName" attribute)....sorry! This works fine in my code so I'm not sure why it wouldn't work for you:
<bean:define id="prodName" name="changeItemProduct" property="productName"/>
<logic:equal name="changeItem" property="productName" value="<%= prodName %>">
....rest of code...
1. I think you might not need the <jsp:useBean>, but this is the right why to use it:
<jsp:useBean id="changeItemProducts" type="java.util.List" scope="request"/>
<jsp:useBean id="changeItems" type="java.util.List" scope="request"/>
2. you should specify the type in <logic:iterate>
<logic:iterate id="changeItemProduct" name="changeItemProducts" type="com.hp.adm.changeIte
3. you missed the parentheses for your get method:
<logic:equal name="changeItem" property="productName" value="<%=changeItemProduc
I think znaps' code will also work.
Let us know.
Hi again,
I tried what you guys said, but I'm still getting the same error: (below for your reference - this is while using kennethxu's code). I also tried znaps' code but am getting a similar error as well. Can this be caused by an error with java or tomcat? I'm not sure why I'm getting this error...
org.apache.jasper.JasperEx
An error occurred at line: 30 in the jsp file: /jsp/common/left_panel.jsp
Generated servlet error:
[javac] Compiling 1 source file
C:\tomcat\work\Standalone\
symbol : variable changeItemProduct
location: class org.apache.jsp.chi_list_js
_jspx_th_logic_equal_0.set
^
1 error
Using this code in jsp:
<logic:iterate id="changeItemProduct" name="changeItemProducts" type="com.hp.adm.changeIte
folCA = insFld(foldersTree, gFld("<bean:write name="changeItemProduct" property="productName" />", ""))
headCA = insDoc(folCA, gLnk("S", makeHeader("Title","#ccccc
headCA.iconSrc = ICONPATH + "ftv2blank.gif"
<logic:iterate id="changeItem" name="changeItems">
<logic:equal name="changeItem" property="productName" value="<%=changeItemProduc
insDoc(folCA, gLnk("S", "<bean:write name="changeItem" property="title" />", "/ADM/GetWorkOrders.do?cha
</logic:equal>
</logic:iterate>
</logic:iterate>
Hmm, this should get it fixed:
foldersTree = gFld("", "")
foldersTree.iconSrc = ICONPATH + "s.gif"
<logic:iterate id="changeItemProduct" name="changeItemProducts"/
<jsp:useBean id="changeItemProduct" type="com.hp.adm.changeIte
folCA = insFld(foldersTree, gFld("<bean:write name="changeItemProduct" property="productName" />", ""))
headCA = insDoc(folCA, gLnk("S", makeHeader("Title","#ccccc
headCA.iconSrc = ICONPATH + "ftv2blank.gif"
<logic:iterate id="changeItem" name="changeItems">
<logic:equal name="changeItem" property="productName" value="<%=changeItemProduc
insDoc(folCA, gLnk("S", "<bean:write name="changeItem" property="title" />", "/ADM/GetWorkOrders.do?cha
</logic:equal>
</logic:iterate>
</logic:iterate>
the trick is this line:
<jsp:useBean id="changeItemProduct" type="com.hp.adm.changeIte
Well, I got it to work...somewhat. I had to get rid of one of the <logic:iterate> tags (in kennethxu's code) because the first line:
<logic:iterate id="changeItemProduct" name="changeItemProducts"/
is already 'ended'. Unfortunately, now, I can't loop thru my array anymore. Only the first item is shown. Any remedies for this? =) (Take note that if I simply remove the backslash in the logic:iterate code above, I get an error already). Thanks.
This is how my code went:
<logic:iterate id="changeItemProduct" name="changeItemProducts"/
<jsp:useBean id="changeItemProduct" type="com.hp.adm.changeIte
folCA = insFld(foldersTree, gFld("<bean:write name="changeItemProduct" property="productName" />", ""))
headCA = insDoc(folCA, gLnk("S", makeHeader("Title","#ccccc
headCA.iconSrc = ICONPATH + "ftv2blank.gif"
<logic:iterate id="changeItem" name="changeItems">
<logic:equal name="changeItem" property="productName" value="<%=changeItemProduc
insDoc(folCA, gLnk("S", "<bean:write name="changeItem" property="title" />", "/ADM/GetWorkOrders.do?cha
</logic:equal>
</logic:iterate>
this time, I toke the code you initially posted and did following:
1. remove 2 include, because I don't have those jsp files.
2. removed jsp:useBean
3. change first iterate to:
<logic:iterate id="changeItemProduct" name="changeItemProducts" type="com.hp.adm.changeIte
4. change the equal to:
<logic:equal name="changeItem" property="productName" value="<%= changeItemProduct.getProdu
and it worked!
I'll also send you the file by email.

you cannot use one tag as another tag's property value, try this:
<logic:equal name="changeItem" property="productName" value="<%=changeItemProduc
