Hi Sushik,

     <page path-info="/myfirstxpl/"   view="view.xhtml">
     <action when="/occurences/action != ''" action="myfirstxpl.xpl">
   <result when ="number!=''" page="myviewChange"/>
   <result when ="number=''" page="not-here"/>
   </action>
   </page>

Run your code after deleting when condition from action...i hope that may be the problem.

THANKS & REGARDS

Re: facing problem with xslt transformation in xpl

In reply to this post by sushik billa

Hi,

Thanks for the reply..

i removed when condition from action tag..but still it didn't work out..

earlier i was running into version problems with exist, so i changed "oxf.xforms.state-handling" to client in properties.xml. I don't know whether this would contribute to the problem that i am facing..

please do let me know if there are any other solutions to get around this problem.

hi sushik,

i think the best is to start with debugging the in- and output. To see
what's going on, just add a debug attribute to the in- or output
elements that you want to monitor. For example, in myfirstxpl.xpl:

<p:param name="instance" type="input" debug="MYFIRSTXPL_IN" />
<p:param name="data" type="output" debug="MYFIRSTXPL_OUT" />

If there's more than one processor in the XPL, you could add the debug
attributes to the processor in- and outputs, too. With the debug
attributes set, the data content of the specific in- or output will be
written to the logs:

RE: Re: facing problem with xslt transformation in xpl

In reply to this post by sushik billa

Looking at your view xform, you have:-

> <xforms:trigger>
> <xforms:label>Number of occurences</xforms:label>
> </xforms:trigger>
> <xforms:action ev:event="DOMActivate">
> <xforms:setvalue ref="action">submit</xforms:setvalue>
> <xforms:send submission="main-submission"/>
> </xforms:action>

I think your xforms:action should be *within* the xforms:trigger - so that
the action is performed when the button is clicked, ie

> <xforms:trigger>
> <xforms:label>Number of occurences</xforms:label>
> <xforms:action ev:event="DOMActivate">
> <xforms:setvalue
ref="action">submit</xforms:setvalue>
> <xforms:send submission="main-submission"/>
> </xforms:action>
> </xforms:trigger>

I suspect your xforms submission is not including a value for the action
element because of this - and this means that the page flow won't be calling
your action pipeline (the test on your action element will be failing)

Thanks for all the support..

'dubug' to output was the key in figuring out solution to the problem, the 'when' conditions in result tag against the output was not right..i had to change those to get it working..
