Problem with parameter & ctrx_nfuse_connect function

Hi all,

I'm encountering a problem using a parameter with ctrx_nfuse_connection function.

I retrieve .ica url with a web_reg_save param, than I use this parameter to try to connect but the error is the following:

Action.c(138): Notify: Parameter Substitution: parameter "ICA_url" =  "https://<customer_URL>/2_19_2014/PMC_RUN_APP_ZTRSWKDHISIUCYKGPZZZP.ICA"
Action.c(138): Connecting via NFUSE portal "https://<customer_URL>/ICAFILES/2_19_2014/PMC_RUN_APP_ZTRSWKDHISIUCYKGPZZZP.ICA"
Action.c(138): Setting connection option "ICAFILE" to "F:\J\sigep\\nfuse_(null).ica"
19/02/2014 14:32:24 Action.c(138): Modifying ICA file with commands "ConnectionBar=0": done with status 2.

19/02/2014 14:32:24 Action.c(138): WaitForEvent: Initializing wait event, time=180000, end time=1366098780
Action.c(138): Error: Connect can not be established - Last Error=64, Last client error=0

The code is something like:

    web_reg_save_param("ICA_url",
    "LB=This object may be found <a HREF=\"", "RB=\">here<", LAST);
    
    web_url("Project List", 
        "URL=<customer_URL_To_retrieve_ica_URL>", 
        "TargetFrame=", 
        "Resource=0", 
        "RecContentType=text/html", 
        "Snapshot=t5.inf", 
        "Mode=HTML", 
        LAST);

    ctrx_nfuse_connect(lr_eval_string("{ICA_url}"),CTRX_LAST);

any hints about that?

cheers,

Jacopo
