Hi,

In a webpage you can use the PRIM_WEB.Json for creating a JSON document.

for example

Define_Com Class(#prim_web.Json) Name(#uJson)
Define_Com Class(#prim_web.JsonObject) Name(#uJsonObj) Reference(*DYNAMIC)

#uJsonObj <= #uJson.CreateRootObject
#uJsonObj.InsertString Key("sample") String ...

Hi Art,

Try to set the value to *SQLNULL before you add the entry to the list.

But the errormessages show something else, they talk about 1.4 not being supported.
In the other screenshot the path says jdk20.
My adivce would be to do a brand new install of SDK1.8 and use the select option (that is show in the screenshot) to refer to that Java installation.

Maybe you could try to install version 1.8 of Java or OpenJDK V8 and then point Integrator Studio to that version.
I am not sure if this will solve your issue but, I have had some issues with Java 1.20 in combination with other products.

Hi,

I have a situation where it is mandatory to add the HTTP header variable Accept-Encoding: gzip to the request.
The API will now return the JSON compressed as expected but how do we now use the JSON?

Is there a utility in Visual LANSA to deflate the data?

Thanks,
Jurgen

Hi,

I can programmatically change the instancelist header name for an instancelist column, this is shown in example DF_T3003O.
But I noticed the column selection menu is not updated, am I able to access the captions in this menu?
In the screenshot I changed the column heading but in the menu the ...

In the layout you use the layout item that manages the header should have sizing(FitToWIdth).
This should now make sure the header takes the complete width.

You can also do this dynamically.

I added the complete code for the sample view I created.

Begin_Com Role(*EXTENDS #PRIM_VIEW) DisplayPosition(1) TabPosition(1) LayoutManager(#Layout1) Caption('View2')

Define_Com Class(#PRIM_TBLO) Name(#Layout1)
Define_Com Class(#PRIM_TBLO.Row) Name(#Layout1Row1 ...

Hi Klaus,

You can dynamically create the header panel.

If you look at the sample code below you can create a placeholder on your view, in this sample this is called #headerPanel.
Note that the reference parameter of this #prim_panl is set to *dynamic.

You can now dynamically instantiate the ...
