Re: Barracuda: setVisible

Hi Kirk,

a custom directive solves this. <table
class="Dir::Is_Visible.ModelName">
Make sure, the model "ModelName" overrides processDirective. Depending
if the table should be visible or not, processDirective returns true or
false.
Check out
src/org/enhydra/barracuda/examples/xmlc/TemplateTableScreen.java there
you'll find an example for this.

Regards,
Stefan
