Tree By Nesting Table Column issue

[Former Member]

Hi All,

I have used a tree by nesting Table Column UI Element in one of my Web Dynpro Applications which displays the list of all Investment Decalrations made by an Employee. Earlier this Application was working perfectly fine. Recently we have upgraded our System to EHP4 SP 24. Nopw we are facing a strange issue with Warning Message "Attribute Must not be Changed." whenever we are trying to expand the node. Because of this we are not able to expand the node.

Does anyone have faced similar issue. If yes, how can we resolve the above problem ?

Your help will be fullly appreciated.

Akhil Rai.

Hi Akhil,

Could you post your solution please,

Presumably your TreeByNestingTableColumn component is mapped to a context element for the "expanded" property. One source of this error message is when the context element is flagged as read only.

Hi John,

Your answer was relevant to me(2nd statement). I was getting the same warning message 'Attributes must not be changed' because i had set attribute as read only and in program changed it's value.

Thanks.
