must not modify the datatype of a mapped attribute

[Former Member]

MappedAttributeInfo(MailOutboundView.excel): must not modify the datatype of a mapped attribute.

IWDAttributeInfo attInfo=wdContext.getNodeInfo().getAttribute(IPrivateMailOutboundView.IContextElement.EXCEL);
IWDModifiableBinaryType binaryType=(IWDModifiableBinaryType)attInfo.getModifiableSimpleType();
binaryType.setFileName("MailOutboundReport");
binaryType.setMimeType(WDWebResourceType.XLS);

i opted for solution2 but i dont know how to start.

In the componentController

i defined a excelfile --binary after that i mapped to the view

In view i need to create another excelfile2-binary.

after that i copy excelfile to excelfile2 of type binary.

then i start modify excelfile2 ?

but in coding , i don't how to do ...

anyone pls help

solution 1

Actually, it doens't matter whether it is view or interface controller, the key point here is that you must modify only "origin" node attribute, not mapped one.

solution 2

So either modify "origin" in used component, or create separate attribute in owning controller, alter it, and then copy elements back and force.

If i created an excelfile in the component controller i am going to modify this

code which is from IPrivateMailOutboundView

my componentcontrollername is IPrivateSmsGatewayAppComp

IWDAttributeInfo attInfo=wdContext.getNodeInfo().getAttribute(IPrivateMailOutboundView.IContextElement.EXCEL_FILE);

IWDModifiableBinaryType binaryType=(IWDModifiableBinaryType)attInfo.getModifiableSimpleType();

binaryType.setFileName("MailOutboundReport");

binaryType.setMimeType(WDWebResourceType.XLS);

component controller name is not need...just u have to access using view name PrivateMailOutboundView its enough.

Hi ,

Just put this piece of code in wdDoInit of component controller... and delete the similare lines in view..

IWDAttributeInfo attInfo=wdContext.getNodeInfo().getAttribute(IPublicSmsGatewayAppComp.IContextElement.EXCEL_FILE);
IWDModifiableBinaryType binaryType=(IWDModifiableBinaryType)attInfo.getModifiableSimpleType();
//set other details using "binaryType"

This would suffice..
