----------------------------------------
Hello,...
well i found the problem i maybe can used my sugestion.
If you saw the attach file I'll be extended the class TableTag and ColumnTag.
After I review the code of displaytag I see there is somethings maybe canbe
updated like this: (just my sugestions).
In TableWritertemplate the method writeTable, has an only big try catch, maybe
its better if this byg try-catch can be separated in the necesary try-catch
over each method calle inside this method, using the corresponding log4j for
example. (that helps to found more quickly any exception).
my problem was like i was extended the TableTag, but with the new version 1.1,
in my code was missing some code aparently now necesary like id, footer, a more
necesary the caption.
if you see my code I set the Caption, but when get inside of
HtmlTableWriter.java i think
is necesary change to something like this:
protected void writeCaption(TableModel model)
{ if (captionTag != null){
this.write(captionTag.getOpenTag() + model.getCaption() +
aptionTag.getCloseTag());
}else{
this.write( model.getCaption());
}
}
that because like this case I'll be setting the Caption using something like
this:
this.setCaption("<caption>"+ tcDataSet2D.getDescription() +"</caption>");
and not using the object CaptionTag. Maybe I need to set in my code something
to set the CaptionTag and not modified the method writeCaption such above write
These are my sugestions, i hope you can review this, i'll be waiting your
commentaries. thanks

> Hi. I'be using this great Tool since long time ago.
> I'be using DisplayTag extended the class TableTag with colunmDecorator,
> without any TableDecorator it works very well until last realese 1.1, when I
> found there isn't still work my apliccation with the last realese.!
> At class TableTag calls to writeHTMLData(); method which calls
> new HtmlTableWriter( this.tableModel, this.properties, this.baseHref,
> this.export,
> out, getCaptionTag(), this.paginatedList, this.listHelper,
> this.pagesize,
> getAttributeMap(), this.uid).writeTable(this.tableModel,
> this.getUid());
> given a NullPointerException at "PageContext" which isn't null. Only I can
> presum the problem is with the "tableModel", in wich the table decorator and
> footer are null. (I'm not using a TableDecorator)
> Can anybody tell me which other characteristic maybe in "tableModel" u other
