[0.3.1] Unable to set value for attributes on type-level about opcua-modeler HOT 10 OPEN

can you explain again ?

from opcua-modeler.

Try to set a value of, for instance node i=11579, where the type is set to "None", somehow the user should be able to select a type first, and enter a value then

from opcua-modeler.

you mean that you create a node variable but somehow manage to set its value to Null when creating it? How do you do that? This should only be possible when creating a extention object, and we create them yet anyway (we can edit them)

from opcua-modeler.

Maybe by copy-paste?

from opcua-modeler.

it is possible to change type of a variable node by first modyfing its datatype then its value, which will then use the new datatype...maybe we have a bug here we should always use the datatype and not the type of the variant.... @zerox1212

I ran into it by copy-pasting attributes from NS0, i think

Can you give me a step by step of what you did? I never used variable types before, and I generally didn't use copy paste.

I can tell you that when you create a new variable, it uses the data type from the selection to set the node data type and the code uses the same data type to create a variant of that type. Whatever is typed in the value box is assumed to match what the user selects, I don't think there is any protection here.

@oroulet , it seems like he is saying that copy and paste isn't saving the value/dtype properly. That is the only way dtype could end up as None (which is different than ua.Null). Perhaps we should check for this condition, and set the node datatype to ua.Null if we ever get a None dtype, then the code would create a Null variant as well.

You can get a "None" type when importing XML nodesets. Open Types->ObjectTypes->FileType->MimeType->Value. Now i see no possibility to set some other type than "None"

bump

This is fixed as far as I remember try master and close issue.
