PhaseIndicator UI element

[Former Member]

Hi, those anyone knows how to use FirstVisiblePhase property of PhaseIndicator UI element. I'm asking because when I try to set this property at runtime a NPE is thrown from framework.

According to the Javadoc, this property should contain the ID of the first visible phase element. Normally, this property will be bound against a context attribute of type String.

Probably, you did that, but the context attribute is initialized with NULL which might cause the NPE (which I consider a bug).

Can you post the stack trace and the version of Web Dynpro you are using?

OK, below is content of error page shown by WDP framework.

Yes, you are right, there is a property bound against a context attribute of type String.

I have phase with ID "SelectAction". In wdDoInit() I do

wdContext.currentContextElement().setFirstVisiblePhase("SelectAction") where FirstVisiblePhase

is name of context attribute of type String.

If I do not init FirstVisiblePhase context attribute everything is fine.

OK, you are right, FirstVisiblePhase property is bound against a context attribute of type string. In wdDoInit() I wdContext.currentContextElement().setFirstVisiblePhase("SelectAction") where FirstVisiblePhase is name of context attrib of type string and “SelectAction” is ID of dedicated phase. In this case error is thrown and I'll include conten of error page in next post. If I do not set context attrib value everything is fine.

Seems to be a bug in SP 9. It's fixed in newer versions.

10x, this saves me a lot of time. Did you know that WDP code generated from SP 10 is not compatible with WDP framework that comes with SP 9 or erlier? And if you know is there some solution? For example patch for SP 9 that doesn’t breaks what SP 10 breaks. 10x again

[Former Member]

What do you mean exactly with "not compatible"?

Generally, you should use the same runtime versions (service pack numbers) in the NWDS and on the WebAS. Service pack versions are compatible, but sometimes the application has to be rebuild in the NWDS such that the code is regenerated.

Yes on my development PC SP 10 was installed and everything was fine. But when I deployed WDP ear on machine with SP 9 installed a runtime exception was thrown (NoSuchMethodException). If you open WDP project build (code generated) on machine with SP 10 with NW on machine with SP 9 you will see that the problem, becomes from code generated that is nor compatible with WDP framework that comes with SP 9.
