Hi all,
we use for our application a mobile a psion teklogix 7535 with
Windows 2003 mobile .net version 4.20 that has capability
to render WebDynpro as IE 6.0 (so layout is full WebDynpro
compliant).
Unfortunately the performance is very poor so we want to
force rendering using sap-wd-client=PieClient. This is
work well, but using Exit Plug in Interface View cause a
wrong url.
This is a full examples:
We launch application1 with http:http://host:50000/WebDynpro/dispatcher/local/Prj1/App1?sap-wd-client=PieClient
The application1 has exit Plug and we call it using
String url = WDURLGenerator.getApplicationUrl("local/Prj2","App2");
// now url contains http://host:50000/WebDynpro/dispatcher/local/Prj2/App2
wdThis.wdGetMenuInterfaceViewController().wdFirePlugGotoUrl(url);
After this i'm expecting that url is
http://host:50000/WebDynpro/dispatcher/local/Prj2/App2
or
http://host:50000/WebDynpro/dispatcher/local/Prj2/App2?sap-wd-client=PieClient
but the url generated is
and was raise error saying
The Web Dynpro Application 'HuCreate' has expired. Please restart the application either with the refresh button or click the following link HuCreate.
Details: No details available
If I remove manually the two parameters from url
sap-wd-cltwndid=...
sap-wd-appwndid=...
the application start well.
The question is:
How can I force url to be generated correctly? or Where is my error?
Thanks in advance to all

I've fix with a workarround using external jsp page shown below. This page clear the extra wrong paramiter sap-* except for sap-wd-client. This wa works well but is not the final solution.

No... i'm sorry... this is not a good solution. url grows with too many parameters.... soo after some recursive call (A call B, B call A, A call B) the url becomes too big....

I Found a workarround that work very well.
I added the two param
sap-wd-cltwndid=...
sap-wd-appwndid=...
in url using
String url = WDURLGenerator.getApplicationUrl("local/Prj2","App2")+"sap-wd-cltwndid=&sap-wd-appwndid=";
// now url contains http://host:50000/WebDynpro/dispatcher/local/Prj2/App2
wdThis.wdGetMenuInterfaceViewController?sap-wd-cltwndid=&sap-wd-appwndid=().wdFirePlugGotoUrl(url);
and all works well!
