FormAPI Problem

Sorry, It's basic but I want value of item xyz?

<item name="level1">
<label>Level 1</label>
<replicant max="1" min="0" default="1">
<container combination="or" hide-name="t" name="newPage">
<item name="item4">
<label>Item 4</label>
<replicant max="1" min="1" default="1">
<item name="xyz">
<label>State</label>
</item>
</replicant>
</item>
</container>
</replicant>
</item>

I am getting null -- var conItem1 = IWDatacapture.getItem("/level1[0]/newPage/item4[0]/xyz");

replicant/container items are 1 based arrays, not 0. So you need "/level1[1]/newPage/item4[1]/xyz".

This assumes that level1 is not null. If it is, your code will break, depending on where you're trying to access the value.

Current Environments:
(1,2) TS 6.5 on W2K3
(3) Vignette V7 Portal on Solaris 9

Nicholas

I tried with 1 also but it was also giving the null, well tried once again same getting null.

and Yes one replicant should be there always.

jbonifaci

You might also have to do NewPage[1], as that is a container as well.

Nicholas

No success. Strange, it is really that tuff?

LooseCannon

what version of teamsite

Nicholas

I am trying it on TS6.5 on WIN3K and also on Solaris 9.

Not working at both places?

1) as of 6.x the <replicant> tag was no longer supported. you should use iterating containers instead

2) you have to call getValue() on an item to retrieve it’s value

3) <item name="xyz"><label>State</label></item> is nothing more then a readonly field. What type of item is it select, text, radio, etc...

Nicholas

1) I want some solution with replicants only as its something related to upgrade and I sould not remove some of existing functionality.

2) When I am trying getValue, even then it is not doing anything.

3) I am accessing Text and Textarea.

Please let me know.

Thanks Nicholas

code changes are part of the upgrade

Nicholas

That is what I am trying to do ...leaving the existing part as it is and just using existing values to set with new fields. And I suppose this is the basic functionality, I don't think there is no way to do this. May be someone else able say something here?

The point I failed to make was, during an upgrade you need to make all necessary code updates (datacapture.cfg, iw.cfg, formAPI, PERL, whatever...).

You're looking to resolve a datacapture.cfg issue with formAPI, instead of fixing the datacapture.cfg.

You need to update the datacapture.cfg...

just my .02

Adam Stoller

In an effort to make Loose Cannon's comments a bit more clear... you need to change:<item name="level1">
<label>Level 1</label>
<replicant max="1" min="0" default="1">
<container combination="or" hide-name="t" name="newPage">
<item name="item4">
<label>Item 4</label>
<replicant max="1" min="1" default="1">
<item name="xyz">
<label>State</label>
</item>
</replicant>
</item>
</container>
</replicant>
</item>to:<container name="level1" max="1" min="0" default="1">
<label>Level 1</label>
<container combination="or" hide-name="t" name="newPage">
<container name="item4" max="1" min="1" default="1">
<label>Item 4</label>
<item name="xyz">
<label>State</label>
</item>
</container>
</container>
</container>
</item>(I might have gotten some of the translation wrong, but hopefully you now have the idea of what LC was talking about)

Thanks Adam, Well changing the DCT not looks good for me.

Thanks Nicholas

Adam Stoller

You seem not to be understanding - it's not an option, it's a requirement. If done correctly, the result will be - structurally - identical to what you already had - and thus no change will be needed for any pre-existing DCRs.

I suggest you experiment in a copy of the branch - with samples of pre-existing DCRs (all with their EAs intact)

He only really needs to change it if he wants to use the Datacapture6.0 DTD. According to Interwoven in the 6.1 release notes doc ts.610.rn.pdf page 18 Datacapture5.0 DTD is still valid (unless there's a more recent docuement stating differently but i looked through the 6.5 documentation and release notes) if he's still using Datacapture5.0 DTD then things should work fine. Also in all the documentation on FormAPI I've read (both 6.1 and 6.5) they still reference the <replicant> tag and I would hope Interwoven would've removed those references if it was truely unsupported. Obviously,there are benefits to do the changes to go to Datacapture6.0 DTD but if 5.0 is still valid as the release notes document says it is then that makes the change a much lower priority. And I will say I'm not having any problems with replicants in TeamSite 6.5 using the Datacapture5.0 DTD. So if Datacapture5.0 DTD truely is unsupported I'd like to know from Interwoven, and they should update their documentation to say so. As of right now though, I'm not seeing anything in the documentation that states otherwise. If I missed something please let me know.

Nicholas

Adam, I am understanding. But the thing, I don't wanted to spent lots of time to modify my all DCTs.
btw, Here is the solution. I am able to get the values now.

item = IWDatacapture.getItem("/level1[1]/newPage");
item_child = item.getChildren()[0];
item_value = item_child.getChildByName( "xyz" ).getValue();

Thanks Nicholas
