My code is :

boolean b,cb1,cb2,cb3,cb4,cb5;

int x;

tablePC.addColumn(column2);

tablePC.addColumn(column3);

tablePC.addColumn(column4);

tablePC.addColumn(column5);

tablePC.addColumn(column6);

container.addChild(tablePC);

tablePC.setFooterVisible(false);

tablePC.setVisibleRowCount(3);

tablePC.setRowSelectable(false);

}

}

}

// //wdThis.wdGetEstimateappsController().Reset();

}

wdThis.wdGetEstimateappsController().wdGetContext().currentContextElement().setClickPopupCreateButton2(false);

How thsi error can be removed.

Hi Saurabh,

It seems that you have written a code in wdModifyview which is doing set or get operation.

if(wdContext.nodexxxx() !=null)

Please write your current code inside this if condition stating your node name instead of xxxx and you may not get this error.

Vivek

Hello Saurabh,

Please format it and also tell us what is the code available in line no.467!

Hi ,

It seems you are trying to access some value which is null (for example you dont set the value of boolean b - context value attribute so it is null , you can set the initial value of the value attribute to false). When you compare a null value with true or false runtime error will come.

suggest you to debug your code line by line and you will find out the error urself.

Use "code" tags to format your code and mark the line where the exception occurs.
