Hy Volker,
the use of rendered will fail with tc:sheet variables, for (maybe
the same reason as the JSTL problem).
<tc:columns rendered= ...> runs perfectly with variables,
that have been defined as beans on inside faces-config.xml.
For any reason, the use of variable-declaration inside the tc:sheet
(here currentLine) fails barely.
The variable instance seems to exist, cause JSF can locate
somewhat by using the expression "currentLine.booleanBeanAttrib1",
but the result is strange. Iff you use the debugger and place a
breakpoint into the isBooleanBeanAttrib1 methode of your data-bean,
then you may find out, that the method is never been called.
Anyway the varibale #{currentLine.booleanBeanAttrib1} returns
a true, ughh where did it come from ??? that's weired!!!
In order to circumscribe the bug, i defined a listviewer boolean attribute
and received the expected result.
As a consequence of this, i assume that there is a bug in tobago,
with the internal sheet-tag handling of the var(iable).
Anyway any workaround is welcomed, cause this is a blocking-point
for my work.
Thank you all
Groovie
I opened a bug in Tobago for further discussing:
