Hi,
I have developed a Page Flow application that has more than one entrypoint into
a given set of pages that perform updates to a database. Depending onwhere the
user entered the pages from I want to return to that page once the personhas
completed making the updates. I have been toying with the return to pagebut
that only works to go to the previous page and no further. I was thinkingI could
set a variable in the globalApp class that would point to the initialentry page
but I would have to do that in the .jsp and I haven't quite figured outhow to
access globalApp from a .jsp. Is this the best approach or are therebetter ways
of doing what I am trying to do? Has anyone done this sort of thing andhave an
example?
Thanks,
John

Answer 1

Thanks suggestion from Eddie and Gregory! Actually Eddie's suggestion by putting
everything in a single line did work, however I encountered a even weirder problem:
I am using a plugin called Chime Pro from MDL, by putting everything in a single
line, the plugin is able to render picture on the test brower on server machine,
however, the picture still won't be rendered on the client browser (on another
PC with plugin installed), the weirdest thing is that when I start the TCPtrace
utility:http://www.pocketsoap.com/tcptrace/, the plugin start to work.
I initially think it may due to the port problem, I switched the server port to
the common 8080, it still won't work.
Does anyone in this group use Chime Pro plugin? Any suggestion is appreciated.
Thanks

Try putting everything on a single line; it looks like the \n's at the
end of the taglib definitions are putting returns in the output page.

Hi Eddie,
Thanks for the hint, by using <netui:content/> tag, I did get rid ofthe HTML
<span> ...</span> wrap. However, I still got several empty lines beforemy output
(please see the attached returned-format.txt and the format_wanted.txtand the
screen shot ), this causes my plugin refuse to render the picture.I think those
empty line is due to my code below, somehow the WLS output newlineif I have code
on that line "
<%@ page contentType="chemical/x-mdl-molfile"%>
<%@ taglib uri="netui-tags-databinding.tld" prefix="netui-data"%>
<%@ taglib uri="netui-tags-template.tld" prefix="netui-template"%>
<%@taglib prefix="netui" uri="netui-tags-html.tld"%>
<netui-data:callPageFlow method="GetMolbyscode" resultId="jpfMol">
<netui-data:methodParameter value="{url.Sample_code}"/>
</netui-data:callPageFlow>
<netui:content value="{pageContext.jpfMol}" >
</netui:content>
I think we are getting close to solve the problem, but this maybe adifficult
one due to workshop's own setting.
Thanks!

Try using the <netui:content/> tag; this simply writes the text to
the output stream and does not wrap it in an HTML <span>...</span>
as
the <netui:label/> tag does.
Let me know if that helps...

Hi,
Looks like my workshop debugger is behaving better this afternoon.My apology
for the previous message, the "call PageFlow" did return the stringI expected,
However, the format is little off from what I expected, please seethe attached
return format and the format I wanted.
I have the following jsp code:
<%@ page contentType="chemical/x-mdl-molfile"%>
<%@ taglib uri="netui-tags-databinding.tld" prefix="netui-data"%>
<%@ taglib uri="netui-tags-html.tld" prefix="netui"%>
<%@ taglib uri="netui-tags-template.tld" prefix="netui-template"%>
<%@taglib prefix="netui" uri="netui-tags-html.tld"%>
<netui-data:callPageFlow method="GetMolbyscode" resultId="jpfMol">
<netui-data:methodParameter value="{url.Sample_code}"/>
</netui-data:callPageFlow>
<netui:label value="{pageContext.jpfMol}" >
</netui:label>
Is there any way inside workshop that I maybe able to tweak code alittle to make
the format suit my need, this is critical for my plugin to recognizethe format
to reder some picture.
Thanks!

Hi Eddie,
Thanks a lot for the info.! the "{url.Sample_code}" did solve my
dynamic
data
binding problem, however it looks like it did not return any thingwhen
I use
the following code:
<netui-data:callPageFlow method="GetMolbyscode" resultId="jpfMol">
<netui-data:methodParameter value="{url.Sample_code}"/>
</netui-data:callPageFlow>
<netui:label value="{pageContext.jpfMol}" >
</netui:label>
The method "GetMolbyscode" in the .jpf as following:
public String GetMolbyscode(String S_code)
try {
java.sql.Clob molfile = structuredb.getmolbyscode(S_code);
int len = (int)molfile.length();
String molfil = molfile.getSubString(1, len);
return molfil;
catch (SQLException e) {
System.err.print("Caught Exception : ") ;
e.printStackTrace() ;
return null;
I did use "toggle breakpoint" to step through the excution of "GetMolbyscode",
I got the expected "molfil". I need to particularly mention that
the
returned
string "molfil" contains several "\n" inside it, I am wondering this
may cause
the problem.
By the way, the "toggle breakpoint" debugging function sometimesdid
not work,
I am wondering why.
Thanks!

The NetUI tags use data binding expressions to access data. Oneof
the ways you could do this is to use the "url" binding context,
which
provides access to the first parameter that shows up on the URLfor
each
parameter key; this is equivalent to your getParameter(...) call.
Replace your methodParameter with this:
<netui-data:methodParameter value="{url.Sample_code}"/>
Hope that helps...

Hi All,
I am new to this newsgroup. I am using workshop 8.1 and try to
call
dynamically
the PageFolow method, but it won't work, is there alternatives?
I have the follwing codes:
<%
String S_code = request.getParameter("Sample_code");
%>
<netui-data:callPageFlow method="GetMolbyscode" resultId="jpfmol">
<netui-data:methodParameter value="<%=S_code%>"/>
</netui-data:callPageFlow>
However, it give me the error: this attribute does not supportrequest
time value.
Thanks!
