Couple of thoughts:
When you create a ComboBox with preset values, you enter two sets of things
- labels and values. For example, the Labels can be 'January','February' etc
while the values are 1,2,3. setValue() should always pass the value (1,2..).
Further, if the values are taken as numeric, it is possible that there are
issues with trying to setValue() with a CSpString.
I would like to mention that pageSessionObject is least meant for this kind
of situations. If putPageSessionObject() and the getPageSessionObject() are
within the same web event processinng - within a single http
request-response - the most efficient and appropriate way to pass the values
from some other method to cbCreType_onBeforeDisplayEvent() would be to use
simple instance variables. UserSessionObjects would be another inefficient
but less harmful option. Liberal use of pageSessionbjects results in large
SPIDERSESSION values, which can lead to truncated SPIDERSESSION and all
kinds of problems.
