This is probably JRun-specific so if you're not interested in JRun you don't
need to read any further.
I have a need to reference 2 beans within the same JSP.
With the 0.92 reference implementation I was able to code
<USEBEAN name = "queryAA" type =
"dreba.prj.servlet_utils.JBPresentAISApplication" lifespan = page>
</USEBEAN>
<USEBEAN name = "AISRB" type = "dreba.prj.servlet_utils.PresentAISRBAA"
lifespan = page>
</USEBEAN>
<! Untervening HTML skipped>
<TABLE BORDER="1">
<!Rows 15 to 18 contain dummy data so just loop over them>
<LOOP PROPERTY=AISRB:TABLE_APP_R15to18 PROPERTYELEMENT=ix>
<TR>
<TD WIDTH=156><B><FONT SIZE=2 FACE="Arial">
<DISPLAY PROPERTY=ix PLACEHOLDER="Desc rows 15-18">
</FONT></B></TD>
<TD WIDTH=57><CENTER><B><FONT SIZE=2 FACE="Arial">
<DISPLAY PROPERTY=queryAA:X PLACEHOLDER="X">
</FONT></B></CENTER></TD>
<TD WIDTH=50><CENTER><B><FONT SIZE=2 FACE="Arial">
<DISPLAY PROPERTY=queryAA:X PLACEHOLDER="X">
</FONT></B></CENTER></TD>
</TR>
</LOOP>
</TABLE>
where the AISRB bean property indexed as ix is a String array, and the X
property is a String (yes, I know it's a silly name but the information to
be placed here hasn't been decided yet - for the moment I always return the
string "X").
WIth the reference implementation this behaves as expected.
However, with JRun 2.3 I was unable to compile the page because of errors
like:
line 410: [] can only be applied to arrays. It can't be applied to
dreba.prj.servlet_utils.JBPresentAISApplication.
String res = JSP.beanVal(queryAA[jsp_array_idx0],"X", new
String(jsp_default0));
^
Looking into the generated source code, I see the lines
Object[] x = JSP.getIndexedProps(AISRB,"TABLE_APP_R15to18");
for (int jsp_array_idx0=0;jsp_array_idx0<x.length;jsp_array_idx0++) {
out.println("");
out.println("<TR>");
out.println(" <TD WIDTH=156><B><FONT SIZE=2 FACE=\"Arial\">");
out.print(" ");
{
byte[] jsp_default0 = {68,101,115,99,32,114,111,119,115,32,49,53,45,49,56};
String res = JSP.beanVal(x[jsp_array_idx0],"", new String(jsp_default0));
out.print(res);
}
out.println("");
out.println(" </FONT></B></TD>");
out.println(" <TD WIDTH=57><CENTER><B><FONT SIZE=2
FACE=\"Arial\">");
out.print(" ");
{
byte[] jsp_default0 = {87,97,115,32,88};
String res = JSP.beanVal(queryAA[jsp_array_idx0],"X", new
String(jsp_default0));
out.print(res);
}
What I do not understand is why JRun is treating the queryAA bean property
as an array - the loop refers to the AISRB bean not the queryAA bean.
Is there something I'm missing here? I assume it's legal to loop over a
property in one bean while referring to properties in other beans. If this
is correct, is there a problem in JRun?
Sorry for the excessive length of the message.
