Visual LANSA Forum

Good morning everyone,

I am reporting some issues/changes appear with the SP1 upgrade:

1) #SYS_WEB.Close no longer supported, what is the new way to do it?

2) #FieldName.ShowError no longer supported.

3) #PRIM_LIST.Column no longer supported. Now, how is it possible to build a collection of columns as before? 4) What about the cache management? Before the SP1, after a new release of a RP the old one was still visualized (whithout an explicit cache clean-up in the browser).



Then, some questions not directly concerning the SP1

5) How can we show the description in a column related to a picklist item? In windows (if I am not wrog) is possible setting the usepicklist(true) option.
In the example below, the first column has to show the value shown in the focused field. 6) How can we set the error message on other fields than the inputbox (eg. picklist, number fields,...), as shown in the example below? Thank you,

Andrea

Hi Andrea

In order

1 - Sys_web.close, which was little more than a wrapper around the JavaScript equivalent, had very limited capabilities and didn't work at all in some browsers. Rather than leave the feature in the product that could only work in a very limited way, it was removed.

Closing a browser window is really the responsibility of the user.

Please let us know how you'd used #sys_web.Close so that we can offer alternatives.

2 - The ShowError property should never have been available for the web runtime and would cause a runtime failure if used.

3 - The ability to define a keyed collection of an abstract class using the default Style(Factory) was a bug in v14. The syntax implies that the moment the code refers to the collection instance, if it doesn't exist, it should be created.

Correct usage is to change the Style property to Collection (http://docs.lansa.com/14/EN/LANSA016/PR ... _Style.htm)
If the collection is simply a list with numeric access to the items, you can also use an Array Collection (http://docs.lansa.com/14/EN/LANSA016/PRIM_ACOL.htm)
4 - Cache behaviour depends on a number of features. For production systems, where the URL does NOT have Developer=Yes, a change to a reusable part requires that you compile the main page as well to ensure that a new cache manifest is created. These threads should help

5 - Embedded visualization are not supported in Prim_list. Instead, Prim_list allows reusable parts to be embedded as a cell. This is a little more work for simple cases, but is a far more flexible and powerful technique.

The xDemoWebDataEntry sample demonstrates the technique. xDemoWebDataEntryGrade is the embedded reusable part.

6 - Error state can only be attached to fields today. This is a work in progress targetted for SP2.

Hi Stewart,

Thanks for your very detailed answer.

I still have a couple of questions for you:

About the point 3) (now it works): I use it in order to export a list as a .csv file, but I still have the column-title issue reported some month ago. In particular, it returns only the title of the columns with the property ColumnCaptionType set to 'Caption' (using a multilingual variable).
Columns with this property set to 'Description' return a blank value.


point 4)
I read about your cache management, but in our specific case, also compiling the main page we still got the old RP.
Note that the RP was not a direct child of the main page but the n-th child of one of its RPs.

In any case I will try the same scenario with the SP1.

Thank you
Have a nice day,

Andrea

Hi Andrea,

am I correct in understanding that you see different behavior regarding caching but it is now actually CORRECT in SP1?

There are some fixes in SP1 that assure that a recompile of the WebPage should ALWAYS result in a refresh of all compiled RDMLX, with or without cache manifest. I hope that that's what you're seeing

Regards,
Danny

Hi Danny,

With SP1 I have not yet tried the specific case, but works what I rebuilt so far

Thank you

Andrea

Hi Danny,

the new caching management seems to work

What about the column title (point 3 of my last post)?

Andrea
