Hi,
I do not have a lot of experience in programming custom tags.
Now, having programmed a couple of tags, I think it is kind of strage that I
cannot narrow the scope of variables defined in the taghandler down to the body
of the custom tag.
It would for me clearly gain the purpose of code usability if so was the case.
I hope I have missed something and that there may is a way to configure the tld
file so that the scope of variables is restricted to the body. Here is the code
to clarify what i mean:
TAGHANDLER (shortened for readability):
Public void doTag() extends JpsExtension{
PageContext pc = (PageContext)getJspContext();
JspFragment body = getJspBody();
pc.SetAttribute("testvar", "myvalue");
body.invoke(null);
}
JSP (shortend for readability):
<html><head><title>test</title></head>
<my:testtag>${testvar}</my:testtag>
<!-- now, this should be out of the scope, but it isnt: -->
${testvar}
</html>
I do not want to specify or declare the variable first in the jsp.
I also think that using an attribute to hold the name of the variable used is a
bad idea.
I absolutely want to use EL.
Is there any hope, or do I have to live with it?
Would appreciate any tips and workarounds
Regards Trond
