• jQuery jFlow plugin. How can I have more than one on a single page?

  - by Michael

  Hi, I'm using a very lovely and simple plugin called jFlow that gives me a basic content slider etc. However, I can see no documentation or help on how to get two (or more) on one page at the same time working seperately from one another. At the moment, if I set two up, they almost combine as one, despite having a different configuration from one another. Any help would be great, thanks. Michael.

• Automatically select option from select menu with link

  - by Ben

  Hello there, I am trying to use php (and if not php, javascript) to link to a page and include a "?type=foo" or "#foo" at the end of the link so that when the linked page loads it will automatically select a specific option, depending on the end of the link, from a dropdown menu in a form. I have tried to search for this but do not know what this action is actually called, but I've seen it done before. Does anyone know how to achieve this? Thanks very much.

• Is daisy chaining xslt an accepted practice?

  - by Stephen

  I have a situation where I think I need to daisy chain my xslt transformation (i.e. that output of one xslt transform being input into another). The first transform is rather complex with lots of xsl:choice and ancestor xpaths. My thought is to transform the xml into xml that can then be easily transformed to html. My question is 'Is this standard practice or am I missing something?' Thanks in advance. Stephen

• How can I show a "selection highlighting"-rectangle around a column of a Silverlight Grid?

  - by carlmon

  I have a feature matrix implemented with Silverlight's Grid where users need to select a product. How can I indicate selection with a rectangle around the whole selected column? It is easy to put a CheckBox at the bottom of each product's column, but that is too dull. I would have preffered to use SL Toolkit's DataGrid (with built-in row selection), but it cannot be orientated vertically for a feature matrix... Thanks, Carl

• Unit testing Jade

  - by Strawberry

  Hi, What techniques and design strategies have people used to aid in unit testing Jade applications? In particular, how do people typically go about testing Behaviours - which are tightly coupled to the Agent instance and the Jade environment? I'm aware of the JadeMX project, but this appears to be geared more towards system testing - in particular the message exchange between collaborating agents. Thanks.
