Sortable table with own column header
Hi there!
The following code should show the messages of a members inbox using
a sortable table.
<table class="mytable" jwcid="table@contrib:Table"
source="ognl:visit.member.messages"
columns="subject, from_username, to_username, msg_time, msg_text,
read_msg"
persistent="false"/>
My question are:
1. Would persistent=true cache the members inbox so that new messages are
not shown ?
2. How can I display different stuff as the column headers ? I would like to
get the text from a database where the table column are mapped to the
corresponding textx....
3. i tested the method that will retrieve messages and everything seems to
be fine...however this code only diplays 2 columns and not the
rest....really odd...all other columns are empty althouth the ArrayList with
message objects contains only message object with all values set...
Any ideas?
Cheers!

I would further suggest that to avoid OGNL madness, simply build the
entire String up dynamically in your page .java code. Expose that
String as a getter, like "public void getColumns()". Building the
string in Java code allows you to debug it more carefully and you can
see the actual value that
you will hand to the columns attribute easily.
Then bind using columns="ognl:columns".

Re: Sortable table with own column header
Posted by Mind Bridge <mi...@yahoo.com>.
Hi,
The 'ognl:' prefix determines that what follows is an OGNL expression,
rather than a static string. Have a look at the 'source' parameter of your
table, for example. Its value is 'ognl:visit.member.messages' and because of
ognl: prefix, visit.member.messages is evaluated as an OGNL expression -- it
translates to something like getVisit().getMembers().getMessages() as a
result.
What a proposed essentially is to have an ognl: prefix in your columns
binding and have OGNL evaluate the rest of it and return a string that
describes the columns. In other words, you need only one ognl: in front of
everything and the line becomes something like this:
columns="ognl: 'fromUsername:' + getMessage('_USERNAME') +
':fromUsername, subject:' + getMessage('_SUBJECT') + ':subject' "
Does this help?

Okay, I tried it now. It works for a single column, however i seem to have
problems with the notation for more than one column.
columns="ognl:'fromUsername:' + getMessage('_USERNAME') +
':fromUsername',ognl:'subject:' + getMessage('_SUBJECT') + ':subject'"
does not work yet.
What is it "ognl:'fromUsername:' instead of "'ognl:fromUsername: ...
anyway ?
And why do I need "ognl:" for the id column?

RE: Sortable table with own column header
Posted by Mind Bridge <mi...@yahoo.com>.
Hi,
Please try this:
<table class="mytable" jwcid="table@contrib:Table"
source="ognl:visit.member.messages"
columns="ognl:'subject:' + getMessage('_SUBJECT') + ':subject'"
persistent="false"/>
Basically, 'columns' needs to be a string, and that string can be composed
using OGNL.
In this case it will probably be better to define the column title in the
corresponding .properties file as:
subject = Subject
(or something like that) rather than use _SUBJECT, but of course that could
depend on the specifics of the program.
Hope this helps...

Re: Sortable table with own column header
Posted by sa...@women-at-work.org.
Hello again!
Well I found out that:
<table class="mytable" jwcid="table@contrib:Table"
source="ognl:visit.member.messages"
columns="subject:TheSubject:subject"
persistent="false"/>
Prints TheSubject a a heading.
However
<table class="mytable" jwcid="table@contrib:Table"
source="ognl:visit.member.messages"
columns="subject:ognl:getMessage('_SUBJECT'):subject"
persistent="false"/>
does not work. How can I bind the middle parameter ?
