IWDatacapture.getRootItems() issue

kannan_r

Hi

we have issues with authors copy-pasting wrong url's , so we wanted to make these fields as non editable ( can be selected from cgi-call outs only )

Formapi does this obviously . we need to make the element as read only so that the user has no option except to select from browse button.

I want a generic formapi which parses the entire data capture changing relevent portions alone .After going thru several posts related to this topic I was able to copy paste something similar to what i am expecting.

I have attached the code for reference.

The attached code just changes the first occurrence after that it fails .

Not clear why IWDatacapture.getRootItems() is not returning all root elements , or am i missing something in my code.

Current environment is

TS 6.1.0 Service Pack 2
Solaris 9

Sailesh

At any given point in time there will always be one root element, you should be using getChildren()

That's correct for XML Type DCRs only. For DCRs of IWOV Type you can have as many root elements as you want

A small update

the generic form api code actually parses thru the entire tree , its able to return all the elements( Name & type ) correctly.

I am trying to set all Item.getType() == 'browser' as read only using
IWDatacapture.getItem(get_chidren).setReadOnly(true);

even through Item.getType() == 'browser' matches a couple of times , setreadonly fails after the first attempt.

In other words I am able to parse thru the tree , get all relevant elements , the program exits after setting the first element to read only , if I dont set any element to readonly then it finishes thru the entire tree.

I'm just starting to look at your code - and already I see some very questionable stuff:

...
function processroot(Item) {
Items = Item.getChildren() ;
    if (Items != null)  {
        for (var i = 0 ; i < Items.length ; i++) {
Items = Item.getChildren() ;
            processChildren(Items[i]) ;
        }
    }
}
...

I'd strongly recommend changing the variable name highlighted in red - maybe call it 'children' - and I'm not sure which array your attempting to dereference in purple - the original Items or the internal Items - in fact, give all this - I think the red line should just be removed and purple then becomes blue (so to speak)

Looking at it a bit more - I think you're over-complicating things - I believe the following will do what you want with less code but reasonably cleanly and understandably:

// I prefer a top-down approach ...
function init() {
    navigate_structure("");
} 
function navigate_structure(item) {
    if (item == ""){
// Note: I take the 0th element only
        //Not sure if this changes for "iwov" style DCTs, only tested with "xml" style  
        item = IWDatacapture.getRootItems()[0];
    }
// recurse if we have a container or replicant
    if (item.getType().match(/(container|replicant)/)){
        var children = item.getChildren();
        for (var idx = 0; idx < children.length; idx++){
            navigate_structure(children[idx]);
        }
    }
    else {
// otherwise, process the item - test for what we want in another function
        process_item(item);
    }
}
function process_item(item){
// here's where you test and do what you want
    if (item.getType() == "browser"){
        item.setReadOnly(true);
    }
}

Hope that helps.
I recommend using distinct and descriptive names for functions and variables, and also indent your code (I took the liberty here - but the stuff you posted was very badly indented [if at all]).

thanks very much

I totally agree with you .. The code that was attached had no indenting & no formatting.

the original code which works was

"IWDatacapture.getItem("/page[1]/article[1]/articleImage").setReadOnly(true)"

from one liner ..it grew by copy pasting to the code which I had attached earlier.

today after a bit more searching I found

http://devnet.interwoven.com/forums_vb/showthread.php?t=5151&forumid=13

I am just adding the following line

if ( itemObj.getType() == 'browser'){IWDatacapture.getItem(itemObj.getName()).setReadOnly(true) }

its able to set the value as readonly for the firsttime and after that it fails.

Without having at least a sample DCR, preferably with its associated DCT - it's kind of difficult to figure out why the code I posted isn't working for you -- or are you just not using it? I tested it on a pre-existing DCR (of type "xml") that had a number of browser fields within it - and it seemed to work just fine.

Here comes the code

exactly same as in http://devnet.interwoven.com/forums_vb/showthread.php?t=5151&forumid=13

except for the condition to set type = browser to readonly.

As mentioned earlier the code sets only the first `browser` element to readonly .

where do i need to look for errors ??

I think the issue may be within this horribly formatted code:

function genIdentity(itemObj) {
var children = itemObj.getChildren();
if ( itemObj.getType() == 'browser'){
IWDatacapture.getItem(itemObj.getName()).setReadOnly(true) 
}

if (children) {
for (var j=0;j<children.length;j++) {
var replicantchildren = children.getChildren();
if (replicantchildren) {
for (var k=0;k<replicantchildren.length;k++) genIdentity(replicantchildren);
}
else genIdentity(children);
} }


}

I posted code that works (albeit for "xml" style DCRs) - you got it for free - try using it ... the only thing you might need to change is at the beginning of the process where you might need to loop through the root items as you do in your current code - other than that - everything should be able to stay the same.

Thanks for all your help

I am having a feeling that the whole issue has nothing to do with parsing code

now i am trying to set

IWDatacapture.getItem("/page[1]/article[1]/articleImage").setReadOnly(true)
IWDatacapture.getItem("/page[1]/article[1]/articleImage1").setReadOnly(true)

both these are type==browser .

No getRootItems , No recursive functions ...Just 2 lines of code

articleImage is set to read only
articleImage1 is NOT

could this be something to do with running older TS & Solaris versions .
