Inline style condition on row value does not work Repeat Layouts



The Developer has written an in-line When rule for the purposes of changing the in-line style of a cell in a grid, dependent on an underlying property value.

For example: -

<pega:choose> <pega:when java='<%= (tools.getStepPage().getString(".MyProperty")=="0")%>'> background-color: red; </pega:when>     <pega:otherwise> background-color: green; </pega:otherwise></pega:choose>

However, when the grid was displayed at run-time all of the cells appeared with the same colour, regardless of the property value.

As portion of the HTML is embedded in between '<%'  and '>%' symbols this indicates that this is server-side code (Java). So a more viable comparision would be to replace the '==' with a call to the method equalsIgnoreCase.

Similarly, you may want to get a better understanding of the values that MyProperty may have.
So, for example, changing the above line with the code below will output the actually property value to the PegaRULES log

ClipboardPage myTempPage = tools.getStepPage(); 
if (myTempPage != null) { 
    oLog.infoForced("Full contents of page: " + myTempPage.getXML()); 
    String strIsLimitApprove = myTempPage.getString(".IsLimitApprove"); 
    oLog.infoForced(".IsLimitApprove = [" + strIsLimitApprove + "]"); 
    String strIsLimitApprove = myTempPage.getString(“IsLimitApprove"); 
    oLog.infoForced("IsLimitApprove = [" + strIsLimitApprove + "]"); 
} else { 
    oLog.infoForced("DEBUG :: step page not found"); 

<pega:choose> <pega:when java='<%= (tools.getStepPage().getString(".MyProperty")=="0")%>'> background-color: red;     </pega:when>     ​<pega:otherwise> background-color: green; </pega:otherwise></pega:choose>

TIP: To get instant feedback on the contents of the PegaRULES log file you may wish to use the command 'tail -f' to send the most recent contents directly to the stdout.

Syntax: -
prompt$ tail -f PegaRULES.log

Or, for systems running on a Windows OS you may wish to use BareTail
