convert '() to list()

Veena,

This doesn't make sense. The hiCreateTabField (or indeed any other function in SKILL) doesn't expect anything in list() or '() format. They require list objects, but they don't care how the list was formed. A list is a particular type in SKILL, and the  list() function and '() function are just two of many functions that can construct lists. list() builds a list from the evaluated values in its arguments, and '() creates a literal list with no evaluation - that's the only difference. So converting between the two makes no sense as it's unnecessary and once the list is a created, nothing has any knowledge of how it was created.

Perhaps if you can describe your bigger problem or provide the code that has the issue, we might be able to give more specific advice?

Regards,

Andrew.

Andrew,

Thanks for responding.

The problem was that the ?fields argument was assigned nil. Hence hiCreateTabField failed. I had one more query. Hope I can ask it in the same post. 

I am unable to get the tab names used in the form by providing tab value ?

I tried the following; Created a sample form; See sample code below;

1. f=hiGetCurrentForm()

-- Returns form Id

2. get(f->tabFld  nthelem(f->tabFld->value f->tabFld->fieldList))

-- Returns page3 { as third tab was selected in the form) instead of tab name.  Is there anything I am missing here. How do I get the tab name from pagebasename# ?

Thanks,

Veena

Hi Andrew,

Could you let me know if it is possible to get the tab names by providing the tab value in a given form.  Am I missing something while creating the tabField ?

Thanks,

Veena

Hi Veena,

There are several ways to achieve this. One is to rely on a property
on the form that is named such that it suggests it should be treated as
private and liable to change:

pageName=nthelem(f->tabFld->value f->tabFld->_hi_altNames)

for example, this would give page_flow2.

Personally I don't like this. For a start, it depends on a private property
(the underscore at the beginning is the clue), plus it's encoded - so
spaces get collapsed to underscores, and so on.

So what I would do is store your tab names on each page. After the
hiCreateTabField line in your code, I'd add:

foreach((page tab) tabFld->fieldList tabs_to_be_displayedL
  get(tabFld page)->myTabName=tab
)

Now when you want to retrieve the tab name:

tabName=get(f->tabFld nthelem(f->tabFld->value f->tabFld->fieldList))->myTabName

so this would return "Setup", "flow1" etc.

Andrew.

Hi Andrew,

This is awesome. This logic never stuck me. Thank you very much.
